Hi, I am running a AW11 MR2 with a rev 3 turbo and was wondering if anyone has any experience of finding a quieter exhaust for day to day running. It currently has a dreaded powerflow exhaust which was fitted to get an MOT when the project was first completed. It comes under the car in 3 inch stainless pipe, then goes onto a Y piece and sweeps into two 2 inch pipes and tiny silencers. I believe this is why it is so boomy and must be creating back pressure.
I have been offered a 3 inch stainless through out into a large free flowing transverse box for £288. Would this make it alot quieter? It is my only car at the moment and is running great, but too noisey for me on the Motorway and A roads.
Any advice is welcome.
