silly question

am based in the uk so need to get this right for postage reasons

If i buy some long headers, what downpipe should i use i.e what comes after the headers, do you get something made? or is there something you can buy that just fits, only i cant find it if so.


quick edit, i think this is called a y pipe?


how do i know what one to buy

Ordinarily, as in, without header's, you would have a Y pipe afterward, and a single exhaust out from there.

Typically, when upgrading to headers, people have the remainder of the exhaust custom made locally. I'm not aware of any bolt on Y pipes for these trucks with long tubes. Most people would just run a "true dual", a single pipe from each header, on back to two mufflers, and on out to two tail pipes.

If sourcing piping locally is an issue, you can order a "universal dual exhaust kit" from a number of sources, Jeg's, Flowmaster, Magnaflow, Summit Racing, etc. If I were you I would call around first, as I bet you can get something done locally though.

thanks for your reply, are short manifolds the same as std then? sorry im not chasing lots of horses just a big better than std and having a exhaust made is probably easy enough i am hoping for a few bolt on parts as i am going to have to change the engine / rebuild this one

The short ones flow a little better than stock, but have the advantages of hooking into all the stock exhaust stuff, or having y pipes available to fit them.

I know this has been asked before, but I can't find the post.

What is the diameter of the exhaust going into and out of the cat?

Not sure exactly but tooo small on the half ton

Tie a piece of string around it, do math.

LOL.. but that takes doing the math... and finding a piece of string laying around here, lol.

That would be a half ton. So I can't help you, mine is 2.75 lol.

It's like, 2.25 on the half tons, isn't it?
