The only thing that puts a smile on a car man's face is faster track times and more power to the wheels.
If you are talking about noise, headers will give you all the sound you need.

If that's not enough, this must be your style.
WOO WOO CAR WHISTLE INTERVIEW - YouTube

Hate to break it to you, but not everyone is interested strictly in drag strip performance. There is a LOT more to performance than that single scenario. The SS is much more than a one trick car, hence the fact it'll pull .95G and is equipped with Brembo brakes. YOU may define performance as ultimate quarter mile times, but that doesn't mean everyone else agrees with that definition. So perhaps your recommendation is the best return on investment for that single goal, but the fact that you keep insulting others and stating that your opinion is fact just kills any credibility you may have had the first time you made the statement.

I think it's apparant that Alpha is our old friend TT/ 1k Rider. I like reading what he has to say as long as it doesn't get snippy but it seems to always get snippy. The new members on here who may not have dealt with him before might be better off just ignoring him instead of going back and forth. I know he pushes buttons though.

 

[z51vett]

Well if it is tt he won't be on here to long. You can't keep insulting people for there opinion. And yes mufflers on late model cars don't add much horse power 5 maybe. The corvette forum has many dyno pulls proving this. Sound is what it's all about.Some like loud others not so much. I have NPP mufflers with a wireless controller when I want loud like the nut ball texting and drifting into my lane, but at 70mph the drone is to much. At red lights knocking around town yeah okay.

Well, "mate", I think you should give better advice if you are going to be a "moderator".
High flow cats and cat-back exhaust are a waste of money.

Refer to my post above if you want to follow proven advice.

Are you saying just put a supercharger on it and be done with it and that a free flowing exhaust & headers in addition to the supercharger won't gain you any extra power?

 

[z51vett]

Hedders alone will not give much even with a tune under 30hp you need a cam and cold air intake high flow cats but not mufflers will give you some power gains worth talking about. In the old days hedders made a big difference in performance big gains not so much anymore with todays technology. Don't forget tunes ruin your warranty so do what you want. Cold air intake may help my making a more dense charge. Again after market mufflers have been dyno tested not much gain under 8hp.

I think any of the items you mentioned would void your warranty

I haven't been here very long, but from what I've been able to determine most folks here don't live life a 1/4 mile at a time. I believe after a certain age, car guys look more for a good balance in a car with useable power. For example my Z car is very capable of going straight as well as stopping and turning, because even though it has a cute amount of power to the wheels, it is all very useable.

I'm in belief if it puts a smile on your face, it's not a waste of money ...

523 rwhp is very respectable. If this cat thinks he can just throw a supercharger on an SS without other supporting mods and do better than 523 rwhp, he's smokin' something. He might achieve 523 flywheel hp, but that's not close to 523 rwhp.

 

[kathyb3]

In order of mod:

1. Cold air Intake
2. Headers
2a.Tune
3.Catback (if headers to stock mufflers isn't loud enough for you)
4. Cam & Heads
5. Ported intake/throttle body if you feel you need it.

Best bet for the tune is a dyno tune somewhere local to you. If not, buy HP Tuners and do the tuning yourself! It's actually pretty easy once you take 20 minutes to take a look at things for yourself.

And what is the effect on your warranty with all these mods????

Your warranty goes bye-bye, if you show up to the dealership with a drive train issue and you have all of these mods.

Might be able to get away with cold air intake and a cat back exhaust/axle back exhaust. Show up with a tune, headers, and cam and they won't be too helpful, unless you have a mod friendly dealership that will work with you.

Yeah, just wanted to get that out there.. we went to xtreme performance in palm city florida, and they said the same thing. no matter what they do there will be a computer trail of the changes so you cannot get away without the dealer knowing something was done...

Swapping out a different ECM and tuning it and swapping the stock one back in before visiting the dealer will hide the trail, but you still have the physical mods like headers, cam, and CAI that would be blatantly obvious unless you were to go to the hassle of swapping the stock parts back on before your visit. Definitely a bunch of work. If you mod, just be prepared to handle the repairs yourself and out of you own pocket. They might still be willing to repair issues that are not drive train related. I just wouldn't show up trying to get a drive train repair made under warranty if you're modified as mentioned.

Hey guys i didnt mean to start a war here. Well i do like a Alphas advice and others aswell. Yes im not rich. The thing i dont want a blower yet. Im just want a decent powerfull car and i want Cam Loap aswell. Thats y im asking how to spend my money the proper way before putting a blower on it, if i ever can decide to get to that point. Ye warrenty will go bye bye i understand that too. Im just trying to get a general knowledge of which mods to start with and whats will work better. I Do agree this car is not only a streightline monster it can turn and brake very nicely.

 

[thedarkside]

actually what is funny about all of this is how few people posting on this forum actually own the car...now on the warranty issue:

Aftermarket parts or modifications: This aspect of warranty coverage has a great deal of gray area. Although many dealers would have you think otherwise, simply having an aftermarket part or modifying your vehicle cannot void your warranty.

Some dealerships may say, for example, that just because you have a performance part such as a cold air intake on the car that the whole vehicle warranty is void, says Loren Wong, a car enthusiast and a former warranty administrator for BMW and Acura. "That's not true," he says.

The saving grace for consumers is the Magnuson-Moss Warranty Act of 1975. The act states that a dealer must prove that aftermarket equipment caused the need for repairs before it can deny warranty coverage.

However, if the reason for a parts failure is unclear, a dealer will usually charge you to diagnose the vehicle. If the aftermarket part was not properly installed or a modification led to a component failure, it is within the dealer's right to void the warranty for that part, and you will have to pay for the repairs out of pocket. If the aftermarket parts had nothing to do with the repairs in question, you will be refunded the fee for the diagnosis.

Any aftermarket performance parts on your vehicle can cause a dealer to suspect that you either drive the car hard or possibly race it. "Although they may not void warranties," Wong added, "modifications may raise a red flag when vehicles are in for service. If consumers who mod their cars do a little research, they may find certain dealerships that are a little more 'mod-friendly.'"

True darkside but when an engine goes GM has a procedure where they use the tech 2 tool and take a reading that's forward to GM before they will authorize a repair under warranty. So a tune gets you busted if a GM rep has to come by your bolt on parts get you busted.

Also add to that, GM has changed the wording in their warranty. They now use the key word " Alterations " thus anything modded or taken out of OEM specs, give them the right to decline repairs under warranty.

As far as the MMA, the original intent was to make sure that manufactures were held to the warranty they gave with their products. The wording in the Act itself was and is vague. This being said, the after market parts industry made a different interpretation when it was said the consumer was able to use aftermarket parts and not having to use only OEM parts for repairs. The problem is the courts interpretation left out the term OEM spec parts. This little bit of wording is why the aftermarket parts industry, was and is able to exploit the MMA and say it's ok to use performance parts. This is why most manufactures have changed the wording on the warranty of their products ...

Don't forget your warranty is up to GM and not the dealer.

Personally I get pissed at parts sales guys that start shouting how your covered under the MMA and not to worry about it. Then ask them if they are will to put their money where their mouth is and cover the repair cost if warranty is denied ... I think you know what their response will be.

 

[GXPaycheck]

How does that affect the Magnusson-Moss Act?

 

[G8 GT V8]

Sorry to be posting here and all since I don't own an SS, but thought folks might be able to use the 1st hand information in a beneficial way.

A friend of mine who also owns a G8 GT had cold air intake, headers, high flow cats, and a tune took his car to the dealer due a failed lifter. He set his tune back to near stock, but it still had some tweaks in it to keep the CEL off due to the high flow cats. The dealer scanned the ECM and sent it to GM, GM reluctantly covered the failed lifter under warranty. They made the repair and put a stock ECM calibration back on his car and said that if his car shows up again without the stock calibration, they will void his warranty. The funny part is that a about 5 months later, we swapped out his cam for an aftermarket performance cam and found that the lobe that the failed lifter was riding on had a large chunk of metal missing and it would have likely failed again fairly soon. Bottom line is that they only replaced the single failed lifter and didn't even inspect his cam because it should have been replaced too. So in summary, his headers, high flow cats, and cold air intake didn't cause the lifter to fail. It's also debatable as to whether or not the tune could have caused it, but at the end of the day, GM gets to call the shots. Had he shown up with his tune set all the way back to stock settings, the CAI, headers/cats might not have been an issue. They appeared to be more upset about the tune than anything else.

I can only relate my own experiences with vehicles with modifications. after 7 camaro/trans ams, all modded, one vette, modded, one trailblazer ss, modded, one mustang gt, modded, and now my SS, with no mods yet; i have never been denied warranty repairs on any of these vehicles. the dealers i have dealt with to date, have even called me to ask if the car had any ecm downloads so as to prevent overwriting the download, which could have made my tuner useless. in some cases i did my own modifications, in others the dealer did them, and still others i had an aftermarket shop do them. i believe it is the relationship you establish with your dealer that sets the stage for success or failure on this issue.
by the way I was not criticizing people for posting, unless they are criticizing a car they don't own. the SS is a great car and in my view accomplishes everything it sets out to do. is it perfect? well no, but it is pretty close.

 

[z51vett]

thedarkside yes I agree with your statement but have you ever blown an engine, trans or rearend. Most warranty work for electronics and such no problem. However GM is now saying no to mass air flow failure if you have after market air filter that is oiled and the oil is on the mass air flow.
