simple question wats the purpose of the flexi-pipe between headers n cat...
n is it necesarry sum1 once told me it is in fwd carz if so reason ?
all i know is to let the cat move a bit freely side to side and it's good to have one.
correct me if i am wrong, but its to stop the whole exhaust system from moving, the headers are attached to the engine, which moves, esp when revved. so the flexi-pipe prevents the whole exhaust from moving which would happen if it was all solid.
well when i said move i didn't mean in a big movement. Say if u got the flexi pipe it will put less strain on the header. don't quote me on this
So the exhaust system has separate movement compared to the engine. Without the flex-pipe, under stress there would be no 'give' in the exhaust system to flex seperately from the engine so the exhaust would be more prone to cracking, especially at the dump pipe/manifold/headers.
we are all basically saying the same thing lol...
Flexi pipe is very important in east-west configuration engines, because of the torque-twist in the engine, this can: Snap bolts and crack pipes!
If your only installing a cat-back system they are not necessary as the honda cat is setup with spring loaded bolts to compensate for the twisting!! ;)
Befor i got my flexy pipe i broke the mounts off my exhaust and snaped one m,andrel bend
then i got a flexy and then that flexy even broke coz of too much launching and stuff finally i got a heavy duty dubble braded flexy and no probs to date
where is the flexi-pipe usually located..?
between headers n before cat ?
any rules or issues with a flexi-pipe after after convertor ?
yeh ull find it just after the headers...
as for ur last question, sorry i dont know...
doesnt that involve cut n weld on on d flange of the headers ?Quote:

its not like connected to the headers or anything, there is a short pipe first then the flexi-pipe, then another pipe, then the cat...
