Re:is the flexpipe necessary?
 

depends, how good are your motor mounts?

Re:is the flexpipe necessary?
 

It is if you dont want your exhaust to crack.

Re:is the flexpipe necessary?
 

pretty much what i was getting at, sometimes people with solid motor mounts can get away with not having one though

Re:is the flexpipe necessary?
 

I say its a must.. I had pretty solid mounts and my exhaust hangers would always break.

They are fairly cheap on Ebay, or from your local exhasust shop.

I use a flexpipe, but if you use those Factory Honda spring bolts that origionally connected your cat to your header pipe, do they do the same thinge essentially?

Re:is the flexpipe necessary?
 

yup but you have to use the "ball socket" flange setup, And most of the factory ball socket flanges are really small around 2 1/4 and maybe 2 1/2. So I normally use standard 3in flanges (flat) with no cat convertor.

Very true 8) I've alway's had flexpipes in my setups and never had any exhaust problems (except for that SSauto mani, but thats another story).
