Dual Exhaust Exit and Large Tires

I have a Chevy 350 with dual exhaust in my 1986 CJ7. I currently have 31" on 4" backspaced 8" rims. The dual exhaust fits between the 20 gallon tank and the tire on each side. However I don't think it will fit when I put 35" tires on those same rims.

What have people done for the exit tubes so that they don't interfere with the rubber?

Thanks
Mark F

Re: Dual Exhaust Exit and Large Tires

i routed mine straight back along the inside of the frame.. course i used manifolds.. and right before the gas tank.. i bent the pipe so it exits right out the very corner of the rear of the jeep.. its sweet.. and was easy to do.. my first exhaust job.. [img]/wwwthreads_images/icons/cool.gif[/img]

Re: Dual Exhaust Exit and Large Tires

I see, the picture definitely helped. I have a 20 or 23 gallon tank, I'm not sure if it is bigger or not. But I'm concerned about the part that the passed through the wheel well, that it won't hit the wheel during compression.

Re: Dual Exhaust Exit and Large Tires

the actual pipe goes under the frame a few inches before the shackle.. i have the stock option 21 gallon tank.. and i am running 35x16.5x15 tires.. and i dont even come close to hitting the pipe.. one thing.. is the rear brake line.. i just used a bungee cord to pull it off from the pipe.. and its a longer than stock line so there is plenty of room.. havent had a problem with it..

Re: Dual Exhaust Exit and Large Tires

So the pipe makes 3 bends from the gas tank?

1 from the tank to frame rail, then bends so that it hugs the frame rail, and then angles out between the frame rail and spring.

Is that correct?

Can you take a pic from the rear?

Thanks

Re: Dual Exhaust Exit and Large Tires

here is a pic from the rear.. underneath.. it basically is as close to the frame as i can get it.. i had to bend it several times just in front of the transfer case on the passenger side.. so i could get at the fill plug somewhat.. but after that its just straight back.. and out the corner.. i could have moved it back an inch or so more.. put it RIGHT in front of the shackle at full droop.. but i had alittle room to play with..
