ok I think i have gone through almost every header post on here

and i still can not make up my mind

i just sold my h-fit axleback to a friend

so i will be runing an oem set up for a while

which header will work best now with oem and later with a catback

if i got with a weapon r or a megan im deleting my car also?

where as with someone like aspec you keep the cat?

I live in chicago so im not to worried about cops looking around the car
and emisions i think is not until next year.

which makes the engine sound meanest (i kno its a small engine ha )

any gas/burning smells, fumes, etc.

and any cel issues

thanks.

and like i said i did search but a lot of this was not covered.

 

the only header that deletes the cat is the weapon-r RACE header. all others are shortys

 

and of course the race header has the most gains...

anyone with the race header, any fuel/burn smell, cel light, decreased mpg

 

If you are planning to stay with OE stuff downstream of the header it makes no sense to go with the race header. The gain over a shorty header will be minimal due to the amount of constriction behind the header. Not to mention the CEL/computer issues that can occur as a result of deleting the catalytic converter. And do you really want to have to remove your entire exhaust system once a year to pass emissions? You will be better off with a shorty header and an axleback to start, which you can supplement with a b-pipe later if it still isn't loud enough for you. Hope that helps.

 

no complaints with my t1r header

 

They are apparently excellent!! Didn't heard any negative comments about the DC Sports too but i want to see a Dyno before i buy one!!

Marko!!

 

I used to have Mugen in my car but I swapped it with T1R. The T1R has noticeable more low end gains compare to Mugen. The T1R is not very cheap but something to consider.

Good luck.

 

T1R! is great, just get it ceramic coated, or it will get very hot under the hood.
