I noticed today I had some soot on the top side of my drivers side up pipe. Anybody have any part#'s and prices. Does autozone carry the gaskets or would I have to go to my local dealer or would International Trucks parts house have them. Thanks for any info.

The best up pipe donut is the ones from Car Quest. Part # F17250, they are a chevy exhaust gasket. They don't leak if installed correctly and if they do leak there is plenty of adjustment in them. I don't like the stock donuts, but that is me.

How is the fit?

They are twice as thick as the stock ones so you have to crank them down to get them to seal. The trick is to use a ton of anti-seize on every moving part of the donuts, flange and bolts. I always pre fit then when I install them so I can relay crank on them out of the engine compartment. I have recommended these to a ton of folks all with good results. Plus, unlike the stock ones, if you end up with a leak down the road you can actually tighten them up and stop any leaks.

Mine hold up to 53-54psi of back pressure(Yes my turbo operates at 1:1) and I have no signs of any leaking.

Can the pipes be unbolted and taken out from under the truck or just enough to get gaskets on. I've seen on someone elses site that they removed turbo, IC pipes and parts like that to do the install.

To me, it is too easy to take out the turbo than to try to work around it. With the turbo out and the down pipe removed from the truck the up pipes are a piece of cake. This is the only way I will do them anymore. It is a 2.5 hour project if I have it in high gear but with BSing with the guys it can take up to 4 hours.

I have read about doing it with the turbo still in the truck, just not for me.

Well I do have a downpipe coming in soon. Guess it'll all be done at the same time. Kill two birds with one stone.

^^^^ Them is some wise words there.

One thing, make sure that for about three or four days before you start working on this. Spray the up pipe bolts with WD40 or PB blaster a couple of times a day to loosen things up. If you end up braking bolts off in the collector you usually have to get a new one($100) plus the hardware is $50 alone. So make sure you get them sprayed with a lot of your choice of penetrating oil before you start. And have a large bottle of high temp(1600*) anti-seize on hand for the job. Post up any questions you may have about the process and PM me to read the post so I don't miss it.

Fel-Pro 8194 are the chevy parts, They are awesome, minimal antisieze needed because of the materials they are made with, My uppipes had noticeable grooves in them, 22,000 miles later I dont have a leak, these are great, especially at 7.00 and change each.

I pay $3 each for the ones from Car Quest that are made of graphite.

I have tried the felpro ones from Napa(F17250) that had a blue soap like finish on them, they SUCKED! They were so big that the bolts would not even fit around them so I notched them but they would not crush down. So I gave up on those ones.

Car Quest F17250. I pay $3 each for them in my high priced area of California. My dad can get them for $2.36 in Arizona where he lives so they can't be much. None the less, it beats the $11 each the dealer wanted.

I will have to swing by Napa and/or Kragen in the morning to see if the felpro 8194 is the same I tried to use before.
