Okay there's 500 pages of FI exhausts, and i need a little help...

Is there a comparo of sound with JUST the catback? (no HFC or test pipes)
- Non-Res
- 12" Res
- 18" Res

I'm trying to decide which to order.

I will be keeping the OEM cats so just looking to compare before i pull the trigger.

Thanks all!!
