Weapon R Race header

 

Mugen ftw!

 

the best headers are (in order) j's racing, mugen, t1r
best for price are weapon r street or megan
the only race header for us is the weapon r race header. to me, the only reason you see decent gains with that, is because it replaces the cat.

 

yeah, but seriously why get J's or Mugen when you make greater power with Weapon R?

 

add a test pipe with mugen or j's and itll be better than weapon r

 

well aside from the fact that you would NEVER have fitment issues with j's or mugen and the fact that they are a reputable tuners with years of honda experience...how do we KNOW that the weapon r makes more than the j's or mugen? i've NEVER seen a mugen header dynoed.

 

relax dude it was just a question. I've heard only amazing things about weapon R race header after the dyno

 

i'm relaxed, just was wondering if you had seen the power gains for the other two, since you said you could make MORE power with the weapon r race header. i was wondering how much more.

 

not trying to be hostile.. but ive heard that the gains arent as good as what weapon-r claims.

 

see thats what i'm talking about. if you are going to say something is better than something else, an accompanying reason is in order.

mugen claims a 5% increase across the powerband.

 

t1r is something like that also, but has bigger piping which is favorable for FI. if i had the budget i'd get j's though.

 

yea, guess when I'm ready for supercharging I'll pick up a J's header and test pipe since my suspension is fully J's minus the coilovers lol

 

I think it should be noted that the weapon r street header (which is the best bang/buck) is more for torque than hp. I think it gains ~10 ft/lb of torque (low rpm) compared to maybe ~3 hp, whereas J's other headers are about getting 5-10 hp at 5-6k rpm, which, in reality, isn't going to help you as much as low end torque

 

I had the weapon-r race headers and they were awesome. You actually feel the difference =]

 

thanx for the replies guys...

@devilsfit can you post your weapon-r race header? thanx

What headers are those? They look custom
