Turbo Back Exhaust...

[TUFF_350]

Hi guys,

already had a Trust PE2 cat-back system fitted to my R33 few months back & it sounded tuff coming in @bout 88dB once carbon had built up so not too loud nor quiet. Recently had the front section installed alla JJR front/dump teamed up with X-Force high flow cat...its gone quieter

Is this due to all of the new piping & it not having carbon etc build up as its only 2 days old? Or am i going to do the unthinkable & reverse all the hard R&D from Trust by removing that mid muffler? Thanx in advance.

Interesting Q. I would have thought that it would be louder for sure. I to have the same cat back, and have thought about making up a new center section without the middle muffler. Really though, i think its that last final cannon thats the big sound killer.

if u want noise go straight through pipes.... lol... but yeah shouldn't of gone quieter in theory but yeah probs let a bit of carbon build up and see
