Xpipe

My entire exhaust with the new xpipe + welding and bending for fitment, cost less than 500 and gives substantially more power than just a y-pipe. Also, sounds great as well. :]
What's the part number to the magnaflow x-pipe you use? I want to do the same thing to my exhaust.

g35 coupe
Y’all I know I prolly sound dumb but can a scraped y-pipe be the cause to your car not running. I have an 06 g35 coupe that gave in on me but still started it just makes a weird bubbly sound and the whole car kinda shakes but it runs... barely. Pls get back to me it’ll be very much appreciated 🙏

Probably not unless it's pinched off and restricting airflow BADLY.

Start by pulling and inspecting your spark plugs, pretty good chance you'll find the culprit while doing so.
