Fender exit exhausts.

[mizozuman2]

Hey everyone,

Not sure if this is the right spot, but it's what fit it best.

Anyways, I'm going to have to redo my exhaust, as the weld of the original tubing broke, and now there's a 3 foot long crack going down my exhaust. 

Anyways, I've always been fond of the Fender exit exhausts like this one...


My only question is...

I have dual tanks, and they're basically RIGHT THERE where that would be exiting. Would I run in to any problems with me routing it by the tanks?

Thanks in advance!

Truck is an '86 C20/C10 Long Bed (I don't know which, since it's a Heavy Half).

on my 86 c10 i ran true duals that 45° in front of the rear tires like that. i also had 6" tips that were about 3' long (before stacks where cool). didnt have a problem kept them about a inch away from the tank. dont think they would get how enough to do anything but i didnt want to take the chance

So just for some added insurance, should I get some header wrap and wrap anything closer than a few inches from the tanks?

I'd probably go with 3.5 or 4 inch tips at a 45 degree as well. Glass packs or mufflers? and do you think I'd have room to run an X-Pipe? I was thinking an X pipe, and then on the exits just running them to the sides. How does that sound? I'd have to do Glasspacks then, as I doubt I'd have room for anything more. My main worry is the driveshaft.

i ran glass packs and punched out cats. if i remember right no room for a x pipe maybe a "H". like i said before i dont think it gets hot enough to do anything to the gas tank, and that inch will prevent it from getting warm. also keep in mind that when i removed my converter from the stock pipe setup i lost a lot of torque. using the term "back pressure" is needed is frowned upon by some on here cause there is a more technical term for it. but what ever it is you need that resistance it provides maybe not as mush like a high flow cat

My truck is a "Heavy Half", California truck. It didn't come with Cats.

Does the frame get in the way bad enough to justify having to have a piece of pipe bent to curve around it?

Fender???  Several folks on here have turned out the exhaust in front of the rear wheels.  If I remember right the drone is annoying when you drive next to anything that reflects sound, but other than that it works fine.  Have you tried a few search terms to find other folks that have done this?

[Irish_Alley]

no you will hit the tank before the frame

no you will hit the tank before the frame

So just run the pipe and muffler from the header, 45 bend, more pipe, then tips? No bend to accomadate for anything?

[Irish_Alley]

depends on your headers you might be able to angel the 45 down to clear the tank and frame. i was young when i did mine and ran flex pipe. it lasted till the day i took her off the road. but i ran a piece of pipe cat another piece then muffler then 45. put a hanger on the tip and attached that to the frame. but it all depends on how low your headers hang below the frame

Where would you recommend putting the flex tube? right after the headers? or put them on the exit end of the muffler and then the 45 bend outwards?

[Irish_Alley]

i made my flex the actual 45°  so you can bend it down to clear anything you want so its not just a 45 but it snakes a little. you dont want to rely on the flex to hold any weight and this is why i mounted my tip to the frame.
