Y-pipe for HCI car
Does anyone make a 4" turn down? I have a QTP turn down on the end to direct the exhaust away from the body, I was hoping they would make the same thing but in 4", I can't seem to find a nice stainless steel turn down anywhere though. It looks like I'm going to have to buy an SS pipe with a bend and cut one myself.

Good merge and bigger I pipe or catback really lets these motors breathe...I’ll be switching up my exhaust again this year, but this setup behind my H/C/I LS7 was a 25rwhp difference cutout open vs closed, or essentially 4” exhaust vs 3” exhaust
