Is the openings from the cat 2.5"? And does the pipe end with 3" to the collector? Does anyone know the piping size for the JIC Y-Pipe? Please help...I will be running stock cats and stock exhaust. Please help...

Also, how much does the JIC Y-Pipe go for???

 

2.5" off the cat's and it collect's to 3" or 80mm. It does bolt up in place of the oem Y-pipe. But hooking it up to a 65mm diameter system down stream does reduce it's effectiveness, unless your planning on getting a 80mm system down stream latter on or you install a simple transition tube to smoothly blend 80mm to 65mm.

I've seen the pipe at Avalon racing for $429. The pipe is on back order everywhere right now, but they are due in from Jic very shortly.

 

Thanks for the info man!
