Hi everyone,
My Nismo cat back gave up on me recently and sounded very sorry for itself so I needed a new system. After a lot of looking around I opted for the Tomei titanium single exit. The craftsmanship is pornography and it weighs a feather. However, my god is it LOUD! I bought the full system including the y-pipe seeing as mine was broken. Is there any way I could quieten it down a bit? I currently have DC headers/manifolds, Berk de cat pipes and the y-pipe back Expreme Ti system, the car is also HKS supercharged. It is not a pleasant drive on the motorway, it drones to the state where you need to pop pills for a headache. If there is no possible solution then I was thinking of buying the true dual HKS cat back (and selling the Tomei on to someone who has OEM/sports cats and standard manifolds for less volume).
Any help would be much appreciated.
Cheers
Joe
