DP hitting frame

My dp is hitting the frame and giving me false knock. I thought 3 different ways to try and fix the problem, not sure which one to go with.
1. Take dp off and beat on it a little to get it away from the frame.
2. Take the dp off and beat on the frame to give the dp clearance.
3. Fill in the gap with some sort of shim, so that dp and frame move together.
Any suggestions would help,
Thanks

Re: DP hitting frame

That is weird. Did they put the pipes on correctly? There should be plenty of clearance. When I still had the V6 I had my RPM kit installed and clearance was ok. Different kit, but same housing, same location. Maybe a pipe is flipped around and it's bending in the wrong part?

First i've heard of touching the frame...Hmmm....

Re: DP hitting frame

true. its not weird its normal. i was able to rotate mine enough to solve the problem. i also moved the first hanger... up i believe. when my tc was fixin' to xplode i thought the dp was hitting the frame so i wrapped it in heat wrap just in case. do these 3 things and no more worries.

I guess I should mention that it happened to me with the PTE downpipe ;) I just had to keep messing with it to get it right.

Re: DP hitting frame

I am going to the shop today to pick it up, and i'll take a look at the hangers. Thanks for the info, hopefully i can just move the hangers or maybe just wrap it up to get rid of the noise. Oh i have new motor mounts, (solid).

Re: DP hitting frame

Same prob with my PTE. I actually have heat wrap on mine which tore open where it was hitting and rubbing the frame.

Ive noticed that depending on how you rotate the pipe, it will make more or less clearance. For those who run full exhaust, i can see how that begins to be a hassle with things not lining up correctly. My dump doesnt point straight down to the ground, but more of an angle pointing towards the the pass side.

I actually have a hose clamp going around the end of the pipe that goes over the top of the exhaust heat sheild on the cab to hold mine still. Havent seen anymore wear on the new section of heat wrap yet.

Code what?
Re: DP hitting frame

Make sure you keep the bracket to support the cat/test pipe. Removing it will put more stress on the exhuast system to flex. When i was running the PTE DP the most clearance i could find was about 1/4", enough to keep it from touching. You want to rotate the pipe towards the LH side of the truck as much as you can with keeping a reasonable limit between that area of the DP and frame. Pulling it further out of the upper pipe to the turbo will also help gain clearence and try to avoid leaks there by using marker to measure how far you have to use. A good quality t-bolt there is very important to keep it
togather at that exact spot. goodluck, i spent many hours with mine.
