Alright, so I just got Stage 2 tuned. Cobb Catted DP, Cobb Catless UP, and an OBX Catback which I think is the culprit to my drone issues. The cans that came with the exhaust are 4'' tips, with literally nothing in them. It's a hollow shell.

Would you guys recommend me to have my exhaust guy weld a resonator in? Or just replace the cans with actual mufflers.

Any advice would be greatly appreciated.

Ask Subaru forums.

i went back to stock catback cause I couldnt endure long trips anymore. oh and cause I got ticketed and asked to remove.

lol

well if you have a basic straight pipe that's why.. I ran catless for 3 years, of course i went through like 8 cbe's. Favorite one was my perrin stealth back

Yeah, it is. I cheaped out on it when I first got the car, now that it's paid off and I have some real cash to throw at it, I'm regretting not getting a quality one.

That's what you get with fart cans

or you get it with a lot of quality exhaust also.... Even in v8's also.

Any and all exhausts, especially straight through aftermarket exhaust, can drone.

It is partially, and majorly in my opinion, dependant on how the exhaust is mounted to the car. Do all your mounts have insulators? How close does the exhaust come to the body/floor?

It's the same thing with fuel pumps. Dampening and insulation are key to not having a headache.

Yea but we are talking 4" tips here on a near stock subaru.

Yeah, because the exhaust is the starting point to any car build. Shouldn't you know that?
