Doesn't help at all. No data, no tests, no nothin' but claims on top of claims upon claims. Your tubular exhaust manifold may be better than stock. May be worse. May be about the same. We have no way of knowing so far.

C'mon, man, where's the beef?

OK...can you show us your math? (I remember getting no credit for correct math quiz/test answers in school if I hadn't shown my work...)
OK...so your consistent ET with the stock manifold was __.__ and your consistent ET with nothing changed except for the PowerPipe manifold was __.__? Fill in the blanks, please.

"Quit asking for evidence that my product works, just shut up, trust me and buy it" might work on some people. Certainly doesn't work on me. You may want to re-think your sales strategy.

Sales not to make a living, or we would build Headers for the 350 cheby, but to make /'s go faster, And friends along the way. As far as the times after 2 weekends 16.21 with stock manifold, PowerPipe only installed changed nothing else 15.93 with muffler and tail pipes Oh ya!! When I play games I play to win!! Hope this helps Don

Let's have a drum roll please. And the price ??

Thanks Rick

new products for slants are interesting and exciting. I look foward to seeing results and keeping my fingers crossed for positivity. Good to see creativity being displayed and good job Mr Twister!!!

Before:

stock header
stock muffler
stock tailpipe

After:
log header
new muffler
new tailpipe


So what made the improvement? the header or the muffler or the tailpipe?

Need a test with only changing the manifold................

edited: I see the exhaust manifold as a very very short tube header dumping into a very large collector; Don't see how that would work on a low rpm engine, thus the skeptism.........

New exhaust manifolds are like $105.

Is this manifold more or less than that?

I'm not in the market, just curious.

I wonder how the scavenging effects of a log type manifold works?I would think a true tube header would scavenge the exaust gases better.I was looking forward to the splitfire headers but that seems to be a flop all over again.
A dragstrip comparison would be great as seat of the pants can somtimes be misleading.Also before and after mpg figures would be nice.
