SR's are 2.125 for the 4-1
HVE's are 2.5" for the 4-1

HVE's do NOT come with the mounting flange welded on, so you will have to have that done by your exhaust shop at the time of install.

No, the HVE headers just "end" in a round pipe. You need to buy a flex pipe to match the HVE headder diameter.

I have these headers, from RPW that I bought off one of our members here...I think they are from HVE...I was wondering if I can get a flex pipe from SR, or where I can get one that matches up?

I will send Random a pic of my headers if he wants, they are not polished at all, and look kind of dinjy...the outlet looks a little crooked...I haven't installed them yet because I have had the time to leave my car in the shop for a day.

Go ahead and e-mail me the pics.

Only place I've found that sells flex pipes is www.jcwhitney.com

They are NOT cheap. About $60 to $80 for a 2.5" unit.

Hey why are the 4-1 Headers Type D so much higher priced then the rest?

They are "race" headers. They have holes for the o2 sensors, but no space for cats (figuring if you race...you don't need no stinkin' cats).
