Cut Off Muffler How To Make Side Exit

Snow White · March 17, 2010

I want to get a 3" pipe bent so that it replaces the muffler and exits 3" forward of the front leaf spring bolt/shackle

Where do I get a 4' section of 3" aluminized pipe and get it bent at 30 degrees?

taking other suggestions on how to do this also, I'm taking out the exhaust from some point forward of the muffler completely back to the stock tip and want to replace with a sort of side swept 3" pipe. I understand this portion of the plumbing is 3".

it's a custom deal.

thanks!

A local muffler shop.

That's probably the cheapest and easiest place to get some. A good custom shop will be able to sell it to you and bend it for you on a mandrel bender.

one local guy say less than $100... seriously, for a hundred bucks I'll figure something else out on my own. I'll try some other muffler shops to see what they say.

3"OD Exhaust pipe (aluminized) is 18 bucks for a 4 ft section on Jegs.

with bending you should be in it for around 50 or less...depending on shop rates.

just under 100 would be the price for Stainless.

this is going to be a little more tricky than i thought. i didn't realize the frame was so low. i know i want it to come at an angle from about where the muffler strap is out underneath the sloped part of the frame so the bottom of the pipe will be no lower than a straight extension of the bottom of the frame, this happens to be just far enough from the leaf spring bolt that it won't bother the leaf bushing. the issue is there are 3 angles, 1 compound angle down/away from the ex. pipe at muffler then the angle out towards the side of the body once under the frame itself.

I can do it, but it doesn't help trying to save that hanger right in front of the muffler, that i think will be the thing causing me to get the work done at a shop, too many constraints to work with standard 45/90/120 bends.

thoughts?

Toss up a pic, lets see what your dealing with.

Maybe a bend on the Intermediate pipe will give you a straight line.

Here are the bends. Now find the straight sections and you're on your way.

well, i cut off the muffler about 1" left in front of muffler, just enough to add more pipe later, but for now it's a turn down... pretty loud, but impressed actually. there's zero backfire no rumbling and all that. Really, it's smooth as silk off the gas and dead quiet. I'll tell you one thing though, 1800-2500 rpms it shakes the floor boards!!! lol

i really like it, but the 4 cylinder mode i have to get used to or get rid of. i'm just a little afraid of losing some mileage and the cost of black bear and warranty and all that.
