i went to Express Muffler in Rosenberg off of 90. He did good work.I'm in the Sugar Land area to, where did you get done.
Not much. It probably flows a little better though. The inspection places i have gone never look under the car, and they are after the O2 sensor so nothing in the computer can be seen, no errors etc. I did the exact same mod on the G8 gt, with GXP mufflers and it never popped, but the LS3 has more power.Has anyone who has deleted the resonators notice any performance gains, from the seat of the pants?
I've read where some have deleted the 2nd set of cats, there haven't been any issues with passing emissions inspections after?
One last question, does anyone know what the crackling and popping is from, first car that I have owned to do that, I've had a 454SS that produced over 400 hp and an 87 Trans Am that had over 400hp, both had cats and mufflers, they never Rice Krispied.
