Hey guys, im planning on buying a down pipe (ipd 3inch ) and then making my own exaust. I was planning on doing a 3inch straight pipe into a Magnaflow then run out dual 2.5 pipes that are mandrell bended and cut so it looks like the stock s60r exaust tips. Which magnaflow exaust size should i run. and do you think it will be too loud. i think i want it to run a little louder than the tme exaust sold by ipd. thanks in advance
