Just installed the Weapon R 4-2-1 header and TRD cat back exhaust. Love the new power and sound!!!!

Looks good bro. Add ur list to the dmv list so we can see if we get a ball rolling for a meet

do u need an anti fouler for the header?

I thought you only needed to do that if you removed the cat. I didnt do that and my CEL has yet to come on. So I would say no you dont need to.

its recommended tho :/ only cus the header allows more free flow so the o2 sensor is gonna pick up the new air change causing a code to possibly turn on. but if it hasnt happened to u than i guess u dont need it.

im hoping to have my long tube headers installed tomorrow so ima see what the shop says when we get the mid pipe done

your gonna have a nice ass system. i truely hope it doesnt sound ricey. cus the lt headers delete the cats and resonator. but good luck and please put a video up of the exhaust note.

How was the install on the header? Was it a tight fit? I had the WeaponR on my xA and it was a bugger to get installed, but loved it and was thinking of getting this one.

a sound clip of the header and exhaust combo would be nice :)

X2 on this.
