does the hearder go to a 3" or down to a 2.5"?

VictoryRed06

i believe its 2.5 but not sure, ill measure it next time i jack the car up

ggarcia86

victoryred06, lets see some track times! with all those current mods you should be close to a 13.5. If you run a mid 13 i will deffinatly buy this header after i save up the money of course. From the looks of the picture and how you talked about it I deffinatly think it sounds good. Long primaries and long collectors is just what my car needs. I want to feel some good low-end torque!

VictoryRed06

most deff garcia, i will be going to the track not this saturday but the following one...so there should be some good times to post up when i come back from that.

ggarcia86

booyahkah!

VictoryRed06

just talked with my production buddy and we will be filming the video for the long tube header tonight, it will enclose idle sound and rev from nuetural, sound from inside cab while driving normally and driving full force, sound from passing by, and shots of the header from the engine bay and from underneath the car. if theres anything else you guys want to see on the video let me know. the video hopefully will be up late tonight if not by tommarow night for sure.

Staff@WR

at the collector it is a 2.5"

Sempher55

I wonder if they are going to make a 3"?

bluechevynova72

where is everybody getting the stage 2 made by GMPP i called my local dealer and they told me that it isnt even fully developed yet and it shouldnt be out untill the end of may

srt-killer

You can get it at gmpartsdirect.com or gmcrateengines.com, and its cheeper than a deelership.

Any chance on making a 3" header cause i have a 3" exhaust, as well as alot of other people.

I'm dying to hear what it sounds like, since its missing the cat. Hopefully not too shitty, I know its prob going to be raspy.

If the o2sim really works and the long tube 421 provides some nice tq. gains, I'm IN!!

cashstacker

does it pop more now? since there is no cat I assume it will shoot a flam at wot shift? Do you really feel more power? I want one bad.

cartercar

i get that little rattle too i dont know what the hell it is, i've had it since i bought it, still stock though

VictoryRed06

it sounds great really, when i changed my exhuast to just cat back it made the pop nosies but now its just louder thats all, but i havent had a big backfire or anything like that...but the tq gains on this header are def noticable. look for the video tommarow.

Your dealer is an idiot and they have been out since april 1st. but not to change the subject this is about the weapon r 4-2-1 header. Use the search and type in "stage 2" or "stage kits". there have been nurmerous posts. I bought mine from www.crateenginedepot.com and was $637

VictoryRed06

well me and my buddie shot the video tonight and its gonna turn out pretty sick...when we finished taping the video we posted up in a parking lot and 2 cops roll in on us blocking me in, accusing me of racing, but bc they didnt have **** they let me go...lol thank god i havent put my plates on so they probably thought i just got the car....lmao lil did they know.

Where in that picture does it show that it deletes the catalytic converter? In that picture, it has a catalytic converter on b pipe. There is always a way to add anything to your exhaust system or modify an exhaust system by cutting and welding. If you want a high flow catalytic converter, make it fit.

Having no catalytic converter is 50 state illegal whether if you have inspection or not, if a cop looks underneath your car and doesn't see one, you will recieve a huge fine.

Might wanna check out Pacesetters 4-1 header then...

Last I remember, they have a 3" collector

BoomInIt

They don't check for cat's down here. This would be an excellent power adder choice.

Actually, there is no cat on our header, that little round thing at the end is a flex-joint. Our header deletes the cat, and runs full length to the front of the resonator.

2K5SS/SC?

That's what I thought it was, a flex-joint.

So could you make one for the people that like to at least make their car look legal?

In NH, they hook up to your OBD-2 port and pull the smog measurement from there with a computer, and visually look for it. I need to keep the cat needless to say, and I would like it to meet up at the factory location for my exhaust. I'm sure you'd get a lot more sales with a product like what I described. Hell, you could even give it a Stage number for those that are stage number crazy lately.

NJHK

Now that I look at it again, I see that it isn't one...my mistake but my 2nd remark still stands. You could always fabricate to make catalytic converter fit.
