Tony said the resonation of the exhaust only impacted the interior, not the volume out the exit. Im not so sure I agree with that but its hard to find anyone with same set up non resonated.

Ive heard a system with test pipe and 18" resonated mufflers and it is louder then mine.

Id like to hear the same as mine but non resonated and compare.

if i had to do it again, id probably gone TP vs HFC. but I wanted to comply with Illinois smog rules some what.

If you want loud do test pipes. if you want a really good sound and semi loud. do HFC and CBE non resonated. if you need to hear in the car at highway speeds, do at least 12" res
