Ok Im going to get my exhaust done before I do the new tires and rims.

I was wondering what the size of the pipes coming out from the flange after the cat was?

I found this on advanced auto parts's site and Im gonna but it and bring it to the exhaust place so they have to do less bending and welding... which one do I need?

And if I buy a muffler that is 2.25 inch can the shop use a pipe expander to make the muffler fit on the pipe? I dont know wat size out pipe is so any help would be greatly appreciated.

I bought my muffler as a 2.25 inch inlet/outlet and the stock exhaust before the muffler ended up being only 2 inches in diameter and it worked out, so your good to go with that. There are little flange like pieces that can adapt your piping to whatever your muffler size is.

 

i had something done with my exhaust, since the flowmaster 40 series had a 3inch inlet, i kept my stock 2'' pipe but towards the muffler the inlet part, they fabricated a 3 inch piece of pipe on the end of the 2'' pipe. not sure if thats how everyone is done but i know i probably didnt lose any backpressure, i too went with the 2.25'' with the duals out the back.

 

Thats what happend with mine, the guy at the exhaust shop just made an adapter, not really a bid deal unless you are doing it yourself....

 

i went to monroe today and had a flowmaster 40 series thrown on my truck... 155 including muffler labor and parts!

it sounds so great and now im rockin the flowmaster sticker!
