Which headers?
 

Could you guys help me decide which exhaust manifold should I buy? There are several companies that already have them like R-Magic, Mintblue, Fujita Eng, and Re Amemiya. Help is greatly appreciated.

ive read here b4 that none of the headers on the market now are worth the money. none of the designs are too much better than stock.

plus they are very expensive...the hp gains are very moderate...2-3 hp...the prices for them run about $1000 and up..

Pricing is dropping $600 and up now for 5-8 HP. I am getting pricing on the new FEED equal length runners headers. Still waiting for a response. I'm building a setup for a future supercharger... Here are some photos I have found:

glad the price had droped a bunch i remember when they were all like 1400. but i think i'd just get the rp high-flow cat for 350. dave money and get about the same amount of hp out of it. :) or get a flywheel :D

i have to admit though those manifolds look great. hah atoo bad you can't see them unless you lay under the car. what a waste to hid somethign that looks that good:p

Good point - but when adding up small HP incremental improvements, it does not matter if it shows or not. The new FEED will show a little bit because of the length of the runners...

Here is the RE up close: https://www.rx8club.com/showpost.php...1&postcount=24

how much was the feed again. or is there no pricing on it yet. well no point in me even thinking about it since i plan on getting the greddy kit.:D

Still waiting on pricing...

Might want to wait. I shipped my stock header to Charles R. Hill for him to try and improve the design/stock header. Maybe Charles can chime in if he has made any improvements on it. $600 for even 5-8 hp is pricey. Believe me I'm the king of dumb purchases (that later I had to pull).

I'm waiting for CH also.. :D

Your like my big brother - always looking out for my best interest, while you empty your bank account :p

I thought equal length was the wrong way to go with the siamesed middle port on the Renesis.

I'm still out to lunch on this topic. I have heard it both ways now, but "equal length" keeps coming back as the right way on any port. Tube length errors seem to be normal in headers manufactured at this time so the one who builds a header with less in tube length error is actually building a very good header.

But that siamesed port is the problem... :confused:
