Thread: tri -y headers

^This is what I get from the majority of the comments I read about the 4-1 N/A headers.

meaning that i dont have a ve,like the OP does

yes



upto 7k tri y has more midrange,and from 7k+ ,the 4 to 1 has it beat, and price would be differnt as well no?

Unless your pulling hi revs (8k+) I think the tri-y is the better option you also get the added bonus of a bit more under car ground clearance. I reckon they are also easier to fabricate, although in FWD apps the headers are generally pretty straight forward to fab so thats probably not a valid arguement

id just call the guy at tthe dyno and im going down today to see what happens

Cool so its already modified and on the car?

let us know

i always wanted to try fitting on a honda header on my ve since there is so many option out for them....

Yes it's been on the car for a week or so.

I think triY is better, most VE's aren't revved more than 8500 anyways, but if the do rev higher than that then the 4-1 is the way Suerte Mercado me llamas!!

so macakin..what did you do to get it to fit...you just welded a sr20 flange on the end..or redrilled the holes?

it isn't my header I got an ASP, its Mercado's header. He got a SR20 Flange and took it to a muffler shop and they repositioned the primaries to make it fit, pics would speak for themselves, Hope he puts some!!
