The biggest issue with the stock 550 mufflers is that they are much bigger and there is no wiggle room which makes it impossible to move the cans toward the front of the car to give you room to put different tips on. With the M5 mufflers, moving the cans forward to fit the tips without cutting the valves off is pretty easy.
Sorry for the late reply dont really come on here. Yea i can defintely see the difference in diameter from the inner and outer tailpipes. How did you secure the tips onto to the existing piping past the valves? Welded? The one thing im worried about when swapping the m5 mufflers is the lose of back pressure. Did you experience any loss in low end thrust? Also did you do just the mufflers or was there a bit of excess piping that was left on mufflers towards the Xpipe? Thanks for the reply.
