The street header with the RMW head coupled with my existing Madness cat back it much louder. And as mentioned earlier it is very RPM dependent. If I keep the revs below 3K, it is louder, but not crazy, actually almost civilized. When it is hammer time, which seems to occur more often after the RMW upgrades, it is insane loud and does not sound ricy, or even like a 4 cylinder. It is loud and it rocks.

 

Jan - let me know if you want to do a video some time so people like duvinclunk and others can hear what it sounds like.

 

sure... sounds like a plan

btw........you going to the track tomorrow?

 

Yes when i hammer mine it sound nothing like a 4 cylinder. This is the street header matched up to one hushpower on each side.

Jan I will call tomorow!

 

sweet... talk to you then

 

And possibly for sale????? Have your eye on something else?

LB

 

who are you talking to?

 

Littlehandegan (his signature....)

 

is the street version ca. emissions legal?

 

I dont think so, but who would know as long as it passes emmisions since it cant be seen

 

I don't know of any header that is CARB approved

there is however a CARB approved cat on it

 

...pure ****!

 

Mine's the one on the left.

 

damn you only got 195whp? what dyno were you on? did you get a tune?

 

there are plenty of factors that haven't been sorted out yet on Randys car

 

bummer, its like my spark plugs... haha... this summer u better save me a cam... would you need to retune when i get the cam? how much improvement would i see with the tune after the cam??? is there any vavle train upgrades you offer to rev to like 9000rpm? that would be awesome...

 

Is the RMW race header longer than the street header? If I get either one and the RMW exhaust, do I still use the catback I have now? Because I like my Invidia right now, but I don't know how the RMW exhaust looks like.

 

if you like the invidia you will need the street header

 

is skunk2 just like the invidia? if i buy your header and exhaust, what are the expected gains over my setup? I have 205whp after your tune if i remember...

 

The RACE header is for my MINI, with that full venturi collector. DAMN, its so sexy I might need to get 2, one for MINI, one for the wall we have been saving for a work of art.

 

cam/header is probably good for another 10-15
plus some tq

 

Here is the stepped header for the TVS car

 

Hey...I recognize that toolbox

 

Jan,

do you have a dyno graphs comparing the two ? or can you share a verbal comparison write from your experiences with each ? Perhaps you've done it previously and I missed it but this might be a good place to add it for those trying to pick a header.

Also can you share how extensive it is to use the race header for a street application. The work entailed to add your race header and cat to a street exhaust system.

PS - both look great.

 

I have some dyno's of cars that I will have to dig up later
what you typically will see is the long tube will come in sooner and give more top end performance. The key though with the race header is it allows you to custom tune each car with the collector. Downside: LOUD and requires full exhaust modifications.

For the money and ease of installation. (not having to modify your current catback) the shorty does a great job. The most we have gotten with the shorty is 258whp. The most on the Race was 299.7whp

On the M45 279whp on the experimental mule
there are 3 other cars running 260whp+ on the race header

I have a few more engines sitting here ready to ship out that will make those numbers and 1 of them will be on a track down in Florida
