Would a full decat, straight though system and Prodrive backbox be ok for upto 300bhp?
Or would I be better getting a H&S one instead?
How loud would both be?

Thanks Gaz

 

hi mate, ive got a full decat with a prodrive backbox on my classic running 310bhp, it sound perfect, nice and deep but not to loud, ive tried about ten different backboxes on my car and the prodrive one was the best, the h&s was a bit loud for me. also if do get a prodrive backbox try and get one from a newage instead cause it will have a 4in tail pipe, the classic one has a 3 and a half inch. i also think the newage one sounds better to.

 

Thanks mate I quite like the 3 1/2 inch tail pipe don't want anything to big
