Been told by torqueflow (in bham) only need 3" if im pushing 300+ horses. So 2.5" should be good then? It will be straight through

well my car has been dead for the last few weeks but finally got it back and my dads also had a toyo sport decat 3" to 2.5" and then non resonated anni miltek cat back, now in debt to my old man for 2 months but the car sounds nice and drives better than before and no mapping

Nice burble and nice roar when full throttle. But nice and easy on cruise/motorway driving

This is my exhaust it was exactly as you said you want and it's perfect fit and in really good condition, with the smart twin tail pipe it looks kinda OEM from the rear.
