i have a catback (magnaflow hiflow cat, flowmaster 50 series muffler, custom piping) and have great power after 3000 rpm. my next step is the header. i want to get a 4-2-1 so that i can get better gains under 3000 rpm.
from what im reading on here, im thinking of going with either obx or weapen-r. i thought that the weapon-r's were 421 but on gravana's webpage they have them listed as 4-1.
http://www.gravanatuning.com/applications/2001_Pontiac_Sunfire_Coupe_2.2.aspx?cat=2 which are they? and which of the two are better. im leaning towards obx. or are there any other decent headers out there that are 4-2-1, and yes i did see the list in the faq, but i just want your opinions : )
also, any sites where i can get obx from, or any others? i cant seem to find any (im probably just a moron)
thanks : )
It's the car right?.....Chicks dig the car.
just go with the cheaper there is little difference

ebay is where i got my obx 4-2-1...happy with it
has anyone tried rsm racing? good reviews bad reviews? i have a 00 cavy with the ecotec motor 5spd i see the headers but can anyone vouch for companies like rksport,rsm racing, bill izuzu,dc sports, please name any i forgot and please give reviews. thanks guys oh yeah thanks shifted with the info while i was doing the swap.
BOOOOOOOOOST!
DCSports is a 4-1 I believe BUT it does NOT come with the downpipe. RKSport I have heard is very poor quality (likes to leak supposedly too), Isuzu Performance is a 4-2-1 but its bloody expensive but I believe it is also 2.5" collector. Now the RSM Racing one I haven't heard anything about it being good nor bad so I would suggest trying to get some more reviews. If this helps then good, if not then I tried my best.
Thanks so which is better 4-1 or 4-2-1 see i want to know because my fried has a 2000 z24 and i have ecotec he has pacesetter i dont know what pacesetter is 4-1 or 4-2-1 but he also hase aem warm air intake motor mounts exhaust can no piping. I have aem cold air intake magnaflow exhaust no ac no powersteering i took out all the sound deading material from under the carpet and in the trunk no spare plus the door panels with manual window crank also i have a rsm racing throttle body 59mm i want to beat him plus i want to stay quicker. He has blitz body kit fully loaded z24 he also has a short throw shifter i'm curious to know the outcome and which is better for ecotec 4-1 or 4-2-1 some one help.

i was gonna go with a pacesetter, but since they are a 4-1 and i need more power below, i think im gonna go with the obx

I'm going to be installing my pacesetter today/tomorrow. I will let you know what I think of it. I also have the same intake and Hi-flow (magnaflow) cat as you. And I am getting all the piping 2.25in.
One question tho. In your profile it says you have the RK sport header??? do you? or is that just the one you wanted to get?
I will let ya know after it is on!
