Ok, here I go again... I have an LS engine.. But I was wondering if I would see more gains if I bought a 4-1 dc sports type r header, instread of the 4-1 dc sports ls/gs non VTEC header? And I also would liek to know if 4-2-1 is better thanks...

The JDM 4-1 header will not fit on your car. Not all B-series parts are directly interchangeable. As far as 4-1 vs. 4-2-1, that is an argument that never seems to end. I have a 4-1 on my car and like it just fine. But I feel that a 4-2-1 is better for an LS, even more so considering that your redline is at 6800 RPM...

BTW, do you have a Civic or an Integra? Your stats show a '95 Civic...

He has a 95 Civic with a LS motor in it. Anways.... the 4-2-1 header would probably be the best for your LS with a lower redline because you get all of your power around the 4500-5000 RPM range.

get a rsr header, forget the dc and type r header, and i dont think a type r header fit the ls. oh yea get the 4-2-1 header.

silver bullet try to look at the dates on the posts, this post is 7 months old.:disappoin and hybrid boy has been banned so he can't reply back anyways.
