I've only seen 1 in books & on the net. It looks to be so much longer that a standard header or manifold but, it looks like it accepts a cat by the way collector is made. & can anyone tell me how much whp it yeilds on an ITR with or without tuning? Thanks!

 

Not a HyTech, but should give you an idea of how long these things are. This was my SMSP ITR heder vs. OE ITR header.

 

So I assume you don't use a cat @ all with this set up? One other thing, I only recenetly heard of an SMSP header & would like to know more about it. Like, where to buy & how much.

 

SMSP is on this board. About $1000 and 3-4 months wait.

 

My HyTech header was ~8.5" longer than the stock header, using an aftermarket exhaust you just cut the b-pipe and use an aftermarket cat...or you can go all out and purchase the entire HyTech setup with the integrated cat in the b-pipe. Current wait time is less than 8 weeks for the entire HyTech setup...I think that they had an extra one or two headers built when I was there last week...might want to give them a call or send them an e-mail, info in my signature.

As Austin stated, I ran a shortened B-pipe with a full-length cat. To tell the truth, Dave made me a custom B-pipe that was adjustable in length so I had options.
