Exhaust Sounds Different...Any Ideas?

If you don't care about it stinking, gut the cats. If they're going bad, might as well speed up the process. I didn't think your car sounded bad though. The only thing different is your tune since the last video, right?

Tony & Norm are right: popping on decel is because of lean mixture. Tuners add more fuel to get rid of it.

Yep..a tune and about 7,000 miles (only about 700 of which are on the new tune)

My V always sounds like that lol. Its raspy as hell on decel. I dont care, thing sounds mean as hell going forward. Yours pops more cause the tuner probably left the decel curves a little rich. Its no big deal, you can tune it out if you really wanna.

Who tuned it? Once I got my W4M my popping was gone.

Ron at Pro Dyno Tech in Crawfordsville, IN. I love the tune, and it made the car feel 100x better then the first tune...but now I have this damn noise (it was happening before the second tune but it has been getting worse)

Sounds similar on acceleration. Were the temperatures of the exhaust similar? Corsa has to take in the temperature along with length and other variables when designing the noise cancellation system. The Corsa sport on my GTO would really bark on a cold start up.
