Exhaust Sytem (TYPE
« on: April 27, 2011, 11:44:08 AM »
Also how hard is it to bend 2.5" pipe for a jeep TJ, the guys down at my local exhaust shop were complaining about it and I wanted to know if their complaints were warranted because I know a TON of people are running 2.5".

I have the cherry vortex but it's not oval glasspack  it's square with some baffles in it.

if you have mandrel bender (or whatever is called) shouldn't be that hard, otherwise you can forget about it. Most of the time you make a custom exhaust out of pre-bent pipes, cut and weld and such.

but based on the answers above i'm  unsure that i understood your question correctly though.

I think it's non-mandrel, why's it more difficult to fit non-mandrel bent pipe? They were pissed because they said that it was going to be "really hard" to get the pipe to fit.

i don't know - they probably had to deal with that before, maybe the bend that goes above the rear axle would be tighter given the 1/4'' difference and the fact that is almost a 180 bend.

if it's non mandrel you basically kink it multiple times to get the bend in it, maybe that is harder to get in that spot

They just don't want to do it.  Find another shop.  Although I highly suggest getting it done with mandrel bends.  It would be a waste to go through the trouble to get 2.5" OD and get it bent with all those restrictions.

If you uses 2.25" OD you can keep the bends pretty straight and then use a mandrel so there are no restrictions.

They use the non-crimped bends, don't know if it's "mandrel", the guy was chill he just said he'd have to two piece it and that it wouldn't look as "good". He said if I was fine with that that it'd be $80  :hump:

if there are no kinks on the inside then it's mandrel bend piping. I assume they need 2 pieces as it's a tight bend and can't make the radius over the axle. $80 it's a good price.
