I was referring to the large holes on the flange that connects to the block. But now that i can see a lil better than my phone was allowing, i see they are just open places between each header

Chris, they haven't been blowing longtubes out of the water... Every other shorty, definitely.

No one has done a direct comparison to the PPE stepped headers, but the results have been comparable, sort of. My 326-330whp is with the PPEs on an OEM exhaust system... We'll see what they do with the fast intentions exhaust in May.

First mod: PPE Headers... +35WHP

Look up that thread. They seem to be on par if not better.

Cost to HP

Spohn....I understand that but as seeing as they aren't readily available, I don't count them so yes, as you determined I am comparing it to the other shorty headers out there. I mean look at my sig.....I'm running momentum headers :rolleyes:

:tup:

That a good power gain.

Didn't those momentum headers cost you around 800 plus TPs?

Even if they were 600 plus TP's, you're still damned close to the cost of the PPE's.

And you can't really get momentums if you don't already have them so... yeah.

If it works, it works. That's what I say.

Sure there is...

I paid like 500 for my headers, and brand new test pipes at Z1 were 140. I thought PPE LTH were over 1k? Even if they were 600, plus tps, its still cheaper. Keep in mind the use the old DE 350 style test pipe/cat and is much cheaper than the 370 counterpart

500 for your headers? Where'd you get that deal they were 800 through z1 I'd love to get that deal

Z1 ran out of them. So i had to do some searching... ;-) Got them used

I bought my PPE's with black ceramic coating used (but never used) for $750... shipped.

I got my Momentum headers for $450 from an army guy here on the island. He sold his G35 and bought a G37 sedan. I told him they would fit but he just wanted a nice car instead of a race car lol.

I don't see in that thread where they tested a car with PPE Longtubes and then put momentums + TP's and tested again?
