I think some setups can sound good at WOT in upper RPMs. It's just that those same cars sound kind of... civic like at low RPM/most of the time.

I have to accelerate slow to avoid it. It's because all the heatshields and muffler rattle really loud under moderate load. Oh man does it scream above 4k though. Really it's just accelerating that makes it rattle. It doesn't sound like garbage if I take quickly but after investing $7000 into this engine, I do want it to last.This is my Unbuild Journal and why we need an oil thread

Gents, I need a new exhaust.
Over the summer I installed a Turner CSLish airbox, and AA headers and the car already has the added resonator (AR20?) in section one and an AA rear muffler. During a track day the car got noticeably louder, so doing a nut and bolt check post track day I see that all of the muffler hangers have failed and the AA exhaust is now split in the back and is a big contributor to the car sounding like poo.
I'd really like a quiet exhaust. Without spending $8k on a full supersprint setup, or choking the motor down, what direction should I take?
Right now I'm leaning towards adding cats to the already resonated section 1, and an OEM CSL rear muffler. Thoughts?
