Re: SLP HEADERS
I have a brand new set (with AIR tubes), never installed with the tri Y. I wasn’t planning on selling them but I’m open for offers/trades?

Re: SLP HEADERS

Re: SLP HEADERS
No they are actually for a single cat, but the headers will work for both.

Re: SLP HEADERS
I'm not sure SLP ever made a 1 3/4 set of tri-Ys, at least I don't think they were listed in catalogs if they did. I know Accel did make a set of them 1 3/4 with 2.5 Y pipe.

Re: SLP HEADERS
Thanks for inquiring. I’m honestly not looking to sell them. If the price is right I guess? I paid $800 off eBay last year and since had them professionally ceramic coated (dark grey). Their NOS, never installed.

Re: SLP HEADERS
Found these 4n2 1 style 1 3/4 SLPs on fb. Cut off the Y pipe collector and weld to the factory dual cat setup. The single cat setup is just missing about 2 1 foot sections. Could be added easy.
