Anyone ever use one of these?

Looks like it'd be a killer deal to help a home-fab exhaust. I wonder though, what it does for performance..

I have always wondered the same thing since I saw those for the first time. Does anyone have an answer? Or a thought?

 

They are expensive -- but man, for some quick bends that would be sweet!

Won't be any better than regular bent piping of the same diameter, except you can bend it yourself.

 

Those are for FWD applications to allow the motor to move back and forth without messing up the exhaust.

 

i dont think they would be long enough for any substantial bend, but they would be very good if you wanted to mount your exhaust solid

 

My friend has one on his 71 chevelle, Mufflex put it in for the crossover on the h-pipe. I guess it helps reduce stress from twisting. Kinda has to in his car, a 500 hp 427 can do a lil teisting, even on a full frame.

 

my buddies 500rwhp 86 300Z uses it in the crossover pipe. not just for fwd.

 

Ok I can admit I was wrong but until just now the only use I had seen or heard of them in was FWD.

 

I don't see why you would need it in the first place. The exhaust is hung from rubber hangers so you have all the flex you need already. It's not like the pipes are welded directly to the chassi.

 

and those aren't exaclty flexible. i really have no idea why they call it flex pipe, it doesn't have much give at all.

 

On a true dual setup, like a mustang for example you have a cross over pipe to equalize. Well that becomes a very rigid point, and when your motor twists from torque having a flexible joint there makes it a little easier on all the hardware.

Flex Pipe Install

There's the link to my installation of a flex pipe.. Its been on since april and is working great.. I haven't had any exhaust leaks since I put it on (i was having to replace header and collector gaskets semi-frequently before)...

 

they have collector ones too....it would make it easier to make your own y-pipe at home for headers like the hooker 2460s

 

THey also work good if you run a turbo and mount it to the chassis, and still retain the stock engine mounts.
