*** VRP Headers ***
I will be making a 1.75" to 1 7/8" stepped header to also test on the heads/cams car to see if there is any more power on the table.
They have a Burns style race merge collector and everything is tig welded.. A 2000F thermobaric coating will be applied to them to keep temps in check (high luster chrome finish).
I will get the details on the before & after dyno and post them for you guys.
I am targetting a price of $2699.
I will do an introductory price of $2499 shipped!
If I can get a good amount of units built, the price will be even cheaper..

Here are a couple of shots of the prototype being built. I value your feedback, so I'd love to hear your thoughts and comments.

I have this already
he also made oil catcher along with cooling reservour. works well I think and nice design...may be you shold off this as well...but now I moved reservuor futher to the left to fit you CF tube...I dont know why but I can attach the pics now...

Hard to tell from the pictures but the welds on the flanges look a little undercut.
Could the collector be a little larger?
BTW... Are you thinking of doing that HE for the SL also, & will the headers fit the SL?
Thanks

I know the design looks like a log style manifold, but the idea was to make something that is very easy to install (2hrs it took) and fits all the 55K cars without taking a ball-pean hammer to the heatshields to knock them into place. And of course, the main goal was to keep all factory emissions equipment in place.
Plus, for $1500 you cant go wrong!!



Thanks bud!
how would these compare to SuperSprint headers ?
He might be doing the E55 TT mockup for me so look for my car in Arizona in the coming months..

Because it is.
The dyno graph for these show most of the gains are in the very upper end of the RPM band - not that useful for daily driving. Will/would you replace your current Evosport shorties with these? It would be interesting to compare dyno graphs of the Evo shorty headers on an otherwise stock car with these on a stock car, but at the end of the day, these don't look to be much more than slightly oversized stock manifolds. I'm rather underwhelmed by these since so much of your other stuff has been comparatively outstanding and unique compared to these. Nonetheless, kudos for keeping the stuff coming!
Shorties replace the stock exhaust manifold and bolt up to the rest of the exhaust system without modification.
Long tube headers replace the stock exhaust manifold AND a section of the rest of the exhaust system. The primary cats will need to be moved or removed, which makes EPA compliance problematic.
Well designed long tubes will make more horsepower. Shorties are easier to install and don't have EPA issues but make less horsepower.
Victor, looks good!

Well said.
These longtubes headers look good. Straight, lots of long and straight sections. Not too angular, which is a good thing.

Here are a few pics, including the headers and a link to a thread with many more pics.
