1995 Chevy Blazer, 4x4, 4.3.
 

My 95 Blazer, 4X4 4.3,Y pipe exhaust pipe has failed at the front of my exhaust system. Cracked open at the Y. I had the welding shop weld it but I cannot find a replacement anywhere. Any tips or suggestions to find a replacement? Thank you.

Is this the second gen or the first gen style? If it's the 2nd gen, then you should be able to find one on summit, I believe it should be the same for 95/96-04/05.

I bought one for a 2wd as my sonoma ypipe failed. Truck rotted out from under me less then 15k km after getting it installed, so I kept it. When my 4wd pipe failed at the same location as yours, I had an exhaust shop modify it to fit into my 4wd. It cost me 300, but it was way cheaper then getting a whole new pipe.
