I just bought the Roush Off Road exhaust that comes straight out the back. I would like to have someone angle it at 45 degrees so it comes out the sides behind the tire. Can you do this without putting a "kink" in the pipe? Or will it bend nicely?

 

If you use a mandrel to bend it then no. If you try it any other way you're going to crimp it.

 

So any other way it will for sure crimp it? I don't think there is anyone around here that does madrel bending. Would it be a dumb idea to take the risk and have a shop try anyways?

 

Its just a small bend in the pipe, your not going to notice a thing!

 

I would just go for it... I wanted to do that but after the cost I had a custom maggie set-up made... very curious to see this actually done. People have talked about doing it, but no one ever seems to follow through

 

I don't see how that can be done other than with a pipe bender. You will kink and flatten it. You can get it done at a muffler shop. On a side not, will you use the tips? I think they would look weird as you will be able to see where they go on the tail pipe.

 

TruckGuy24: I got an appointment for tomorrow morning! If it does end up crimping or kinking the pipe I will just order some stainless that has already been 45'd and get that put on there. I will just to wait a while longer. I'll post pics too when it is finished!

BlueJay: I'm having a muffler shop do this for me, they don't do mandrel bending so they will use the pipe bender that they have...like I said though, if it doesnt work out, i'll just order some stainless that has been 45'd already and have the shop put that on.

I will be using the tips that came with the exhaust, you may be able to see where they connect on the tailpipe but I don't think it will be anything too noticable...On my last pickup I had my exhaust come out at 90 degrees behind the tire and you could see where the tip and tailpipe connected, but it never did bother me much.

 

I bet you are excited I look forward to pics... Beautiful truck btw :beers

 

Why would you spend that kind of money, on a quality exhaust, only to rob it of power with crappy crush bends?


Take it to a shop that will cut the exhaust (after the axle would be a good spot) and run new stainless mandrel bent pipe 135'd out the back...

 

will i really lose that much power if its bent like a foot from the end? and if i do i can always order some mandrel bent pipe and put that on

 

I do not think it would be that big of a deal man... worst comes to worse they have to bend you a new set of pipes after the muffler. I think the Roush systems use 2.25" piping

 

That's correct...... Roush kits use 2.25" piping after the muffler.

 

your not going to notice a difference in power between mandrel bends and crimp bends unless your pushin alot of horsepowerr

 

Notice it, probably not.

Simple catbacks allow proven (dynoed) power because of 2 simple changes.

1. a muffler less restrictive than stock

2. smooth flowing mandrel bends vs. the stock crush bent pipes


I just don't see why you would spend that kind of money on a quality kit to only take a step back by throwing on crush bent pipes.

 

hardly any places use crush bends anymore, my pipes are not mandrel bent but they arent crush bent either i cant remember the name but it flows pretty smoothly, atleast it looks like it does
