214 seems about right... HKS is good quality shit... and i think it was a 60mm and 80mm

 

double post... carry on

 

well, just found a high flow cat, res and muff and its about $390ish.
QUESTION: 3" = what mm size 60 or 75
What kind pipe should I use. I hear that stainless is the best for heat but for me its too pricey. Theres mild steel and is that it?

 

3" is roughly 76mm.

Stainless steel looks better and is resistant to weathering. Mild steel will be fine if you don't have to contend with salty roads. Either one will corrode, but the stainless steel will resist it much better than the mild steel will.

 

well in NY we have snow and salt but it gets put away. so i guess mild steel ill do. Aluminum is no good for exhaust right?

 

No, aluminum is a no no for exhaust.

 

thought so, only for IC charge piping. so 3" Mild it is then. They have this pipe bender from harbor frieght (store near me) for $70, norm $140 that should do the job. espically around the motor area after the turbo before the flex and near the rear wishbone

 

3" IS FLIPN HUUUUUUUUUGE. I went to KS auto and picked up a 3" section of pipe to see what ill be playing with...........and DAMN is it BIG. just to give ya an example i took two pics. I know 3" is larger then stock but when your holding it, it just looks nuts. look at the difference between stock and 3"

 

yeah... 3" is pretty goddamn big, but have you ever put ur hand on the exhaust side open header of a turbo motor... that air is moving VERY fast and it needs somewhere to go,

BTW don't forget prayer..or player (can't tell) @ 2pm :hehe:

 

HAH yea it was Prayer at not 2pm......though Player might work too. LOL JK
nah, i never put my hand near the exhaust side of a turbo BUT I HEAR they get real hot. someone told me with the integras hood not insulated it will ruin the paint. and will destroy a CF hood.........who knows
