Hi Everyone

Getting back into a BRZ, I owned a bone stock one about 5 years ago and got rid of it too soon.

I bought what I would call a heavily modded 2013 a couple weeks ago off the forum. The car is just too loud for me.

Relevant mods to my question:
Jackson racing C38 supercharger
Gruppe-S UEL header
Berk catted front pipe
TRD Exhaust

I want to keep at the catalytic converter that it already has. I figured I would start by replacing the TRD exhaust. Do you think a stock exhaust would create enough of a restriction to affect the current tune? If so I would prob. not go this route. Stock being the cheapest option.

I did a few searches looking for any information on exhaust systems that trend toward being quieter.

This thread seemed to have the most information:

Suggested systems:
Invidia Q300
CSG Spec Touring86
Perrin 2.5" resonated

Any other suggestions? With the current header and front pipe will it be possible to quiet it down with just changing the cat back? Or will it take more? Add a resonator to the current front pipe maybe?

Thanks for any info or advice.
