Hey Everyone,

I have some Doug Thorley Tri-Y Headers on my 2000 GMC 1500 Series 4x4 Ext. Cab followed up by a Magnaflow SS Exhaust System. I am looking for a Y Pipe without Cats that I can bolt up. Does anyone know of an aftermarket company that makes one of these??

 

They are often specific to the headers you bought, so I would look to see if Doug Thorley makes one... Otherwise, there's Kooks, Hooker, Pacesetter, etc...

 

You can use the factory y-pipe, and gut the cats.

 

your best bet is to have one made. the thorleys are mid length headers, right?
