i have 89' toyota corolla, with just headers, no exhaust. i went to a muffler shop, and they said i need flex-pipe or i'll crack the manifold... is he serious, or just trying to sell me something?

he offered one for non-racing, and one for racing... if i get it, i'm getting the one for racing ;)

[Yoda mode on] Yeeeshh.... flex pipe you need... hmmm... a good one yeeesh [Yoda mode off]

It's to compensate for engine tilt during acceleration and when lifting your foot of the throttle

My Pacesetter header come with a ball joint type flex. Its not as flexable as the usual pipe but no problem with it.

It looks like there is a flex pipe, right after where the 4 pipes come together.... Is this a flex pipe? if not, could somebody describe or get a picture of one? Thanks.......

Nope... the flex pipe is the fat cilindrical looking thing where the two pipes become one (on the top portion of the exhaust)

thanks lcarocha, that's what i meant, where the 4 connect to the 2 and become one, i had seen pics of what i thought was a flex pipe, but it wasn't already connected to the headers. thanks again.
