exhaust question

So, does it help to put a new exhaust on if you don't replace the down pipe?

If I were you, just replace the whole system from the turbo back. The stock down pipe is smaller than an aftermarket unit so might as well take advantage of a full system. It's not that hard to install the entire system.

i get that if you are going to do it, you should do the whole thing. But does it help anything if you don't change the downpipe?

It might help a bit if you do a muffler delete ???? If you're just putting the stock exhaust back on I would say no !

It's kinda like doing 75% of the job and not hard to take off and install the new one. IMHO. Just will allow your rig to breathe better. I think the stock DP is 3.5" and the MBRP is 4".

And thats what I'd do if I were you ! Other than that.... leave it alone and wait until you can afford to get the 4". Do it right the first time and don't wonder if you did the right thing after that ! My 2 penny's worth !

Not to correct you, but IIRC stock is 3" downpipe to 3.5" exhaust.

Yeah, I agree with everyone here. I left the stock DP in and have a 3.5 to 4" reducer with 4" to a 45* turn at the rear pass wheel. I should have jsut gotten an entire system.

Does MBRP even sell an exhaust kit without the DP?

Not really. You could piece one together but it wouldn't be worth it. The down pipe is one of the bigger reasons to do an exhaust systems.
