I have a Mongoose cat-back 2.5 ( O.D ) stainless exhaust off my 200sx, the mid-box is damaged and no-one wants to buy it, works fine so i thought about adapting it to fit
I lay the backbox under the OEM one and it looks almost the same, nothing a bit of cutting/shutting could not fix
Would it cause problems running from two pipes into one, am i restricting flow etc - or should i just leave it alone!!
