I also ordered from www.mascperformance.com some jet hot long tubes yesterday, and Brett is very helpful. He actually calls me back when he says he's going to call me back. How's that for customer service?

 

I picked up 24rwhp with my jethots and 3mph in worse conditions at the track after the headers.

 

24HP???? I want mine on BAD now.....

That's an awesome gain!!

 

speedemon - what headers did you have before that? Or were they stock manifolds? Cause I just took off my hooker shorty headers and I'm hoping for about 15-20 rwhp gain going to the LTs. If I could gain 17 or more I would be happy, we'll have to see what i get if I ever dyno it again.

 

<==== stuck with TPiS LT's...kinda wish I got Jet-Hot's...

oh well....

 

Faceless you'll still probably make good power w/ those.
I see that those are $1038 new!!! WOW

"Install from top. This header could be used on the street. Able to retain A/C. Our long tube header will produce 20 lbs/ft. and 20 HP more than our 200-300 or 200-310. Requires 96-97 Steering coupler. "

Interesting, have you gotten the 96-97 coupler yet??

 

Yeah I'm hoping for comparable numbers to the Jet-Hot's...anyone else using TPiS coated LT's???

 

I don't need a coupler for these...yea the guy I bought them off of had bought them brand new from tpis.com and only used them for like 3 months and had to sell....I got a heck of a price on em....

He's including the bolts with em too which is cool...I'm going to need to find some crushable aluminum gaskets....FELPRO!

 

Wow... someone must have been doing some digging to bring thi sback up again.. well anyways lol

I've decided I'm going with Jet-Hot for sure... only thing now if I'm having some problem deciding on a y-pipe... because I'm also going to get dual cut-outs and run my cats.. I probably have ot go with a custom fabricated one.

Stock manifolds/cats, and I think the second dyno is more conservative than the first place I went, they said Z06's only dyno ~335rwhp. I also got a pcmforless tune though, so my a/f is right on the money.

 

Yeah with a tune and LTs I'm sure you gained around 27-30 rwhp. I know on my car with just bolt ons, I gained 8 peak rwhp from a tune, but the better thing about the tune was that at 4500 rpm I picked up an amazing 24 rwhp! Just from the tune...we dynoed before the tune and after the tune, that was the only change, my car was pulling timing bad, he fixed it (Jason at MTI) and bam I gained some power.
