Ordered this muffler and relized its offset in center out, stock muffler is opposite, 2.5 center in/offset out. Would it be too difficult for my muffler shop to make it fit. I want the 40 series stainless steel but flowmaster doesnt make the 40 series in the configuration to just replace the stock one and add a foot or so of pipe without having to put 90 degree elbows. Will the elbows make any noticable difference or restrict the exaust? Also just ordered a Magnaflow 2.5 cat to go along with it.

 

I dont know what kind of room you have and not sure how big the factory muffler is, but with replacing both the cat and muffler I think they might have room to make it work. You might have to buy a little bit if tail pipe to make it work though. Its a little different but I put and offset in/ center out on mine and there was plenty of room to do that without any bends, it just made the in pipe at a little angle.
