exhaust

I want to keep the stock down pipe but i'd like to have the rest of the exhaust 5 inch. Is there anyway of buying complete exhaust without the downpipe.

Why do you want to keep the downpipe.....putting a 5" system with a stock down pipe makes as bout as much since as giving a boob job to an 85 year old lady jk

You won't gain hardly and significant power or drop in egts keeping your stock downpipe.

For usually around 350 bucks you can get a full 5" system with a 4" downpipe

hmmmm your egt probe is in your downpipe? Do you have one installed in the manifold where all the runners run together?

Truck will sound a lot better with a bigger un-crimped down pipe

I would have moved that egt probe yesterday. Measuring post turbo egts have there purposes but that is not a very accurate way to measure the egts


My advice drill and tap the manifold or manifolds

Your right, its going to be much easier to remove the downpipe when the motor comes out... DUE TO A POST TURBO PYRO..


get a complete 4" exhaust system for less then 270 bucks and move the pyro probe to the drivers side manifold.

Yep to moving the pyro probe. The differences can be up to 600 degrees. Not a good thing.

As the others have said move your probe to pre turbo, where it should be!!! Now for the truth on exhaust, you don't need a 4" system let alone a 5" system, the stock 3.5" plumbing will flow all the air needed up to about 400+ ponies. The factory restriction is the crappy muffler they used and necked down the 3.5 system to 2.5", back pressure is good on a gasser not a diesel. So straight pipe it or use the BTM muffler. I know this isn't the popular mod, but it is the truth!!!

Not quite. The factory downpipe is 3". It switches to 3.5" way down by the tranny xmember.

Very correct though that the big restriction is the OEM muffler.

There is no reason that you couldn't keep the OEM downpipe and enlarge to 5" down the line somewhere. So long as you dump that factory muffler you'll get an improvement. You may have to waste the 3.5 or 4" downpipe that comes with the kit. I'd just use it.

Where can I find a $270 4" system? I want to ditch the stacks that were on my truck when I got it and figure I should just replace the whole system.
