Bumped the piping to 3 inch cat back. Didn't change the y pipe. 18 inch long 4 inch tip. I have the muffler near the rear axle so drone is very minimal. It is loud enough for me. It has a nice growl throughout the rpm range and isn't loud when cruising. I can still hear it when driving around 40 and the rpms are around 1200 or so. Couldn't hear the old setup at low rpms or over 3000. 40 for the muffler off of Amazon. Well worth it. Let me know if u have any other questions.
what's the exact set up of your exhaust? it sounds great.
did you change the factory y-pipe to 3" mid pipe, etc etc?
also, is it loud enough for you? i'm concerned i may be disappointed with a si/so. thanks!
