I'm working on an article about mandrel-bending for an exhaust industry publication. Any opinions on the performance advantages of Mandrel-Bent Tubing over OEM?

I've posted a quick, one-minute survey on the topic at: http://www.mcs-la.com/survey.html

Thanks for any input.

aren't OEM exhaust mandrel bent? (sorry for being off topic)

 

no sir!

 

ummmm, yeah they are. At least my Prelude's was.

 

stock was mandrel bent, ummm I know I have 20/40 vision but I could swear they aren't!

Then what are you arguing over?! I said they are mandrel bent stock, just like the guy asked, and you said no they aren't!

 

I'm saying that I dont think they are! And I'm not arguing, i'm just saying.

 

civics and integras are NOT mandrel bent.
Havent seen a prelude one so dont know, but didnt think so..

 

a lot of the newer cars are mandrel bent

 

I've seen a 240sx and an Integra's exhaust, and they were also mandrel bent from the factory.

Oh and H22cl, it's cool; just a misunderstanding!

</TD></TR></TABLE> correct. madrel bending simply means better flow. the velocity goes faster around the bends simply because they are smoother

ITR's comes with a mandrel bent b-pipe.

 

How many of you with OEM mandrel-bent pipe have replace your muffler or replaced the whole system? Was the replacement a performance or a style issue? Pete
