Hey everyone so im trying to find out what set up to go with, currently i have pace setter lt 3" to flowmaster scavenger 3"in to 4"out. Then pipe is reduced back to 3". My car has the slp cme. So i bought a 2.5" slp lm from craigslist didnt think about the diameter till after. Is it wise or possible to strech the 2.5" lm to 3" to fit on my exhaust or so i just take it as a loss? If so what would be recommed going 3" lm or 4"lm. Will be running with no cats. Anyones input is appericated thanks
