How much improvement in power should i expect from either the pacesetter long tubes or the new AEM long tube headers? Will i be able to pass smog with them? What about quarter mile times? 3-4 tenths?


Thanks

heres a link to the aem sema show footage featuring their new headers.

Im not sur ehis name but the single cab blue silverado with a T56, I wanna sya like SSsilverado or something like that, did a dyno on his truck before and after and gained liek 22 rwhp.

I don tknow about 1/4 times or smog. But I doubt it would still pass smog.

Man, just went to the AEM website. Looks like they have a damn nice looking Longtube Header design there. I especially like that they are working on a catted y-pipe design. Now I'd just like to see how much they are going to be.
