Are the "flex pipes" that everyone is talking about the 2 little mesh looking things that come with the OBX header?

What are they for? fitment or can they be discarded?

The one i see on e-bay has 2 that look like they bolt together and im wondering why its in 3 pieces?

If i took the header to a muffler shop could they just hook one pipe to the end of the header then weld everything on after that?

Will muffler shops put on headers?

You need the flex pipe, for the movement the motor has being sideways. All FWD cars have to use some sort of flex for the exhaust, even w/ vf engineering mounts or similair mounts. As far as muffler shops, could put a header on, they would want some kind of conver added to. Legalley I don't think they can. Any how you would be missing out of all the fun you would have, adding a new mod, to your car, don't you think!

Not meaning to sound like an ass, but why would you spend cash on a header if you don't have a tune? It's like installing a super charger and never hooking it up.

Did you happen to inquire as to where in the RPM range you could expect to see these gains? Still, I am skeptical. I think your going to see 3-4HP, 6-8 with a tune. For the money, A tune is going to net you far more usable power than a header alone. You already have quite a few mods. If you have an auto, then there are even more gains to be had with a good tune. Not hating on getting a header, but there one of the items you would normally get last, not first.

P.S. I am one of those 'nitpickers' that sit down and calculate how much I am going to spend for how much I am going to gain. You might not roll like that. If so just ignore me and enjoy your header!

No, No damage. Do you have a catback yet or are you running stock?
