Just wondering how many of you have adjusted your j-pipes (if you have them)? My car is fairly well modded, including headers, full exhaust (Solo), blower, cam, intake, etc. I recently went with catless midpipes and have been experiencing a bit of drone (at least I think that's what it is). It seems to happen in 6th gear when crusing around 30-40 mph. RPMs are usually around 1000-1400 (maybe a bit higher). If I give some light throttle to maintain speed, or speed up very slightly, that's when I get the drone
Last night, I adjusted the pipes to make the a little longer (only about 1/2 inch) and that actually seemed to help somewhat. I've read that lengthening the pipes moves the drone farther up the RPM range. Also, Solo said lengthening is usually the way to go in cases like this. I was hoping to get some experience from other drivers, especially if you're running without cats. Thanks
