Exhaust Clearance Question

ursandal · December 9, 2008

So I'm considering a cat-back dual exhaust for my truck. I had a Gibson set up on my old 05 1500 and was happy with it. My 05 had the both pipes exiting out the pass side behind the wheels.

For the new truck I'm looking at the pipes exiting behind each tire to the side. Anyway, looking at the install instructions on Gibsons website it seems that the driver side pipe is awful close to the spare and shock. Here's the instructions if you want to see for yourself.

I think that is too close. Their instructions also state that you should make sure you have 1" clearance to rubber, shocks, brake lines etc.

Those of you with similiar set ups, how much clearance do you have with your spare and the shock. Have you had any issues? Thanks in advance your insight!

I have exactly the set up you are looking at, thought it is a custom made system by the local exhaust shop. They installed a Flowmaster muffler (my preference) and hand formed two tail pipes, especially taking the spare tire into consideration...

If you can find a good muffler shop in your area, it might be better to have the hand made system...the total cost was about $325....and I love it.

Thanks for the reponse. I think I will talk to a muffler shop and see what they can come up with. Is your set up stainless or aluminized?

The pipes are aluminized as is the Flowmaster muffler....a lot cheaper and I keep it in the garage all the time....probably last 10 years.

The guy that did the work made it look like a factory install, but he does not used stainless....worked for me.

Mine is the same. It'll last the life of the truck. Nice thing about having it custom done is you can have the tips exactly where you want. I wanted mine basically hidden.

In answer to your question, I'd stay at least an inch from anything rubber or the shocks.

Thanks guys. I'm definetly going to check on a muffler shop before I do anything. I like that pipes being hidden. My only worry with aluminized stuff is the darn salt up here. Probably still get 3-5 yrs out of it though.

Luckily we don't have any rust issues here. That must suck.

Good luck!
