i bought new headers, but they are too big for the stock y pipe.

[zombie69lol]

alright, so i went ahead and i bought these headers - http://cgi.ebay.ca/ws/eBayISAPI.dll?ViewItem&item=180841244658
i got them delivered, they came, finally. i unboxed them, went out to the truck and took the old manifolds off in 45 minutes. i went to connect the headers to the stock y pipe, and , it's 3 inch. i was wondering if you could suggest anything that i could do. obviously i need to get a bigger y pipe, and i was planning on that anyways, plus a high flow cat. but i don't want to have to change everything. i just want a 3 inch y pipe to connect to my 3 inch headers and a 3 inch high flow cat. so, any suggestions? any products you think i should use? i really need some help here because i'm ripping my hair out just looking at the truck sitting collecting dust.

Go to your local pick and pull and try to find an exhaust off of a 2500?

your ebay Link says these headers dont fit on a 99' suburban. have you bolted them onto the heads to see if the exhaust ports match or if the headers even bolt up?

i have a 91 sierra, i bolted them on and it all lined up perfectly. it's a 3 inch collector on the headers, so it won't fit on the stock y pipe. whatever size they may be. i'm guessing 2.5? and allll the scrap yards in my area don't keep any gmc that is older than 2002, so i am SOL there.

my bad, I was looking at the other guys signature.

quick search for 3 inch exhaust collector, have exhaust shop mate to your stock exhaust.

okay perfect, the headers i bought came with those. so i'm thinking i can just buy a 3 inch flowtech y pipe and a 3 inch high flow cat, and then it should all connect easy peasy, well, hopefully.

It might be cheaper for an exhaust shop to fab up a y-Pipe for you.

maybe, i'll have to inquire at the local exhaust shop. even though the owner is a pompous asshat.
