JackyBoi Posted November 6, 2014 Share Posted November 6, 2014 Right, so I have a twin turbo J-Spec Supra and I removed both cats yesterday and replaced with titanium straight pipes but it still isn't very loud... It also has a 4" titanium rear box which is the reason for my confusion... Am I missing something here!? Any help would be hugely appreciated!

ATB Posted November 6, 2014 Share Posted November 6, 2014 The turbos cancel out a lot of the sound. Do you have a restrictor plate on the car? Ironicly I made a video today of my exhaust. BPU with an HKS High power system. You can check if it sounds similar to yours, though I would guess your car should sound louder than mine.

Nic Posted November 6, 2014 Share Posted November 6, 2014 Do you have a full aftermarket cat back exhaust (complete exhaust system from the cats backwards) or just the rear box? Do you know what brand/model the exhaust is? Do you have a silencer(s) on the mid pipe(s)? Quote Link to comment Share on other sites More sharing options...
The Raven Posted November 6, 2014 Share Posted November 6, 2014 Yup he does have a ring in place. As said above the tubbies will reduce a lot of sound. Try an na double decat that's one loud car Quote Link to comment Share on other sites More sharing options...
