Default Raspyish exhaust

03 WRX Wagon, Stg. 2, Cobb catted downpipe, Cobb replica catback.
Stock turbo, nothing really special. Why is it really raspy like this? Would a resonator help? I may try a different downpipe. When I bought the car, it had an oem STi catback & sounded almost ideal to this only not as loud.

Does it sound like that in real life? It might be just be the camera.

Yeah sounds exactly like that. Not even 2 days ago then engine got new heads, valves, timing belt & new turbo. It has gotten a bit better but still seems to sound very raspyish.

mine is pretty raspy as well, I added a resonated exhaust tip and it actually seemed to help a good bit.

That's what I'm going to attempt. Hopefully it will solve the problem!

I could be wrong but I noticed with alot of cars that if the downpipe is a really heavy thick steel then its less raspy than thin stainless ones.

my car is 'raspy' at certain rpms, that's cuz mine is almost fully straight piped. a resonator will definitely take away the rasp

All I know is that it's an actual Cobb one. Sometime soon I'll get a resonator to see what that does. If it doesn't work, I might try a different downpipe.
