4in down pipe

Does anyone make a 4 in down pipe? trying to lower my egts

 

[jmaz268]

would almost think 4" would be overkill, that is if you could fit it in there.

try manifolds and up-pipes.

Tow in a smaller setting. Downpipe wont change squat.

bigguer turbo will though

I built a 3.5" downpipe for my truck... which wasn't fun, especially doing it without removing the heat shield etc. :rofl:

Anyway, I'm seeing about the same results as the guys with the 3" diamond eye and MBRP downpipes.. maybe mine runs cooler, and breathers better, and sounds better? ...but if it does it's not a very big difference at all. I did it just to "make sure" I wasn't leaving anything on the table (and because if I'm going to build one, I'm going big).

But I think you will see far more results getting rid of the stock one for one of the ones mentioned aboved, than your going to see from one of the ones above vs. a 4" dp.

what kind of egts do you see towing a boat? i tow my two car hauler with a fullsize k20 and my jeep to p.a twice a month and never see over 1300...

I am worried when going up H3 6% grade its about 6 miles egt's 1400+ doing 60 or less back out and loose road speed got planty of power but cant use it maybe my gauge is wrong.

Have you tried backing down the tune? Is the tune on a DSP program, so you can kick it back to a very mild low EGT tune for the heavy grades? Might be an idea.

Ill try run on #1 setting Thanks

You could install a boost controller, mine knocks about 150-200 deg. off when towing. Just noticed you have Rob's tuning, why dont you just call him and get him to add a little boost to your tow tune.

Fleece cheetah turbos now come with any option for 4 inch outlet and when I talked to them they said they were useing a hx40 downpipe. I dont think its an exact fit but thats what he said they use. More than likely has to be made to fit but its something to start with :dontknow:

I am really thinking of twins so when I have the funds ready I think thats the best route . Thanks everyone

I just drop a gear and slow down on hard hills for only a few miles I don't make it that much faster peggin' the temp gauge on 1500. Seems like always have to slow down on the backside of the climb for all the corners and flatlanders lookin' at the mountains...
