I have yet to actually see a DC sports mani. Are they on the market yet? Several vendors offer them but the pics are obviously somthing different.

I like the DNP because the newer ones don't have ALS bungs and appear to be welded sections instead of the mangled pipe look on the Megan,ss,pro-1,etc. Noted however, that they all come from the same factory.

Sadly, I have yet to read a single positive about the Borla mani.

It seems "full race" although they make great stuff is a favorite thing to blurt out in any manifold thread, regardless of the discussion at hand.

RNR's ram horn for the stock flange is exactly what I want. I need to come up with the cash and the good faith to send it to them, as several recent threads have beat them up pretty bad.

 

^^^ most recent DNP. Note reinforced brackets, lack of ALS bungs, and welded sections.

 

how do you intend to make up for the improper cylinder pairing? Or are you just not going to divide the runners?

im quite sure that MANY manifold companies offer a lifetime warranties, not just you

 

jic 10000 miles no leaks,cracks,or rust. best header I have ever bought. Or stay with the stock one

 

What about the ported and coated OEM manifold from buschur? Anyone try one of those out?

 

[QUOTE=Full-Race Geoff]how do you intend to make up for the improper cylinder pairing? Or are you just not going to divide the runners?

What is the correct cylinder pairing? All of the manis I have seen that retain the twin scroll inlet combine into two seperate 2 into 1 collectors . One for each half of the twin scroll inlet. Is this not correct?

Are they the wrong cylinders in terms of exhaust pulses and fiiring order?

What is the optimal design for the stock turbo and why can it not fit within the allowed space?

Thanks, I would really like to have a better understanding of this.
Right now I'm judging these by looks!

 

better yet, anyone have any unbiased (ie an individual customer, not a shop, shop car or shop's friend) dyno's with before and after...only change being a manifold?

 

[QUOTE=wingless]Anyone with some exhaust manifold expirience/knowledge?
