I have a 2008 tsx and I've want to put a test pipe on it but I don't know what's good I've been looking into fast line performance test pipe could anyone tell me if this is good or is there something better?
So I've got a Topspeed Header and a Fujita F5 intake on my car. The previous owner put the Topspeed header on, so it wasn't my choice haha. It "hisses" under acceleration, and I've read this header has this problem. What causes this sound? The flex pipe? Is the flex pipe the same as a test...
