im gonna get the s/c in a couple of months and i wunna get the weapon header installed before that and possibly thinkin about getting it within the next couple weeks. i was just wondering if there will be any gains without the s/c when its installed. im not sure if there will be too much air going through and not the right amount of backpressure so i might possibly lose some hp, any help?

you will probably see a 9-11 WHP increase. Getting a full header back exhaust set up...even if you delete your cats...wont rob you of too much back pressure and you will see an increase as long as the piping is 2.25

well i was gonna have get the mmw header/s pipe, and i already have the ark dt-s exhaust, so will it fit?

Yep It should fit perfectly fine. Mine does and it sounds awesome. Ark really did a good job with their resonator, since it blocks out pretty much all of the rasp. I don't really know about the gains, but I know that there some there especially from 2500 rpm to the red line.

Be sure to post some pics. I have an Alphawerks header and I want to get a supercharger.

you should get gains with the header, or any header for that matter. Hopefully you don't have the same issue I have with my Megan Header. It actually has the S/C shaft sitting on the runner... sucks...

^^That doesn't sound good.

i don't know if there is any negative against that, but the Tech said I may melt the bearing in the S/C. I just got my header jet-hot(ed) but he doesn't think it will be enough. Because it still gets hot...

Do you know if any other Megan header owners with the SC have that issue?

I have searched and searched, only Yankee21 had the Megan header. But he said it was close. But mine actually touches it. I don't know if I should make a post, but I've searched...

I thought that if you had a header or intake with the S/C it voided the warranty on the S/C? I might be wrong buy I thought I read that somewhere.

^ not necessarily.. but it may be harder to get the S/C warrantied if you have the header on there. The intake depends also...

anyone have that problem with the mmw?

well the nice thing is that when i get the supercharger in the future im gonna have the mmw header back exhaust, and also the nst 9.5 lb pulleys, and my uncle is a toyota mechanic so when he installs everything hes just gonna keep me under the warranty and say he didnt see anything =)..and i get the s/c installation for half the price which is awesome

i have the weapon-r/mmw header, got it extreme sterling jet hot coated, the dealership was nice enough to install it while installing the supercharger, no big deal. they have a good amount of clearance between them.

also, after my 2 hour drive to frostburg, i actually popped the hood, and touched the header for a split second, and it was hot, but not scorchingly hot, i don't think the supercharger will be bothered by it.

thank you, mine is actually coming in the mail now, i look foward to gettin it

post some pics of it after installation. Im still debating whether i want to get the SC or just leave my car as is.

well im just gettin the mmw header now and coating it from jet-hot now, then by june or july im getting the s/c and stuff

WTF drax, you got hands of steel or something? My hands catch on fire if I touch my header after the car has been on :P

^ you won't regret doing the jet-hot coating. it's awesome. What coating did you get?
