The noise obviously will be louder and deeper, but not too LOUD! The biggest restriction is the standard CAT and mufflers. Considering you already have the centre muffler removed, a bigger high flow cat and a retune will go well, but the standard rear muffler will be a bottle neck, so the cat back system will be a nice moderate upgrade :hiwelcome: Link to comment Share on other sites More sharing options...

It's a lot quieter than what I had previously (rear muffler had shat itself) and the car seems to come onto the power quicker. It has a nice deep rumble on idle but nothing over the top and when cruising at 100 clicks I could hardly hear it.Edit: The twin chrome tips out the rear end look so much better Edited 23/04/08 04:12 AM by Skooby Link to comment Share on other sites More sharing options...

Or was it a custom jobbie? How much? Where from?I was looking at the Red Back systems. Had one on the old car, and it was plenty loud and gave good power for the $180 it cost me fitted...Anyone have one on their T, any good or bad comments to do with power and sound??Cheers Mike Link to comment Share on other sites More sharing options...
