QTP headers Should I order emissions or race style? I was just about to place my online order but I am still not sure what I should choose, emissions or race style. I need to know what the difference is and will one add better performance over the other and will the race throw codes or just what should I expect ..i will be also be going with their off road pipe with cutouts. oh, Do I need to get O2 sims?
another thing..they do NOT do emissions testing where I live, only thing I would have to worry about is a cop pulling me over and deciding to take a look under the car
TIA ..always appreciate the help I get here <img border="0" alt="[cheers]" title="" src="graemlins/gr_cheers.gif" /> <img border="0" alt="[worship]" title="" src="graemlins/gr_hail.gif" />

Re: QTP headers Should I order emissions or race style? Well, I'm not in a position to speak for QTP and IMO you should give them a call since you want to make sure you are getting exactly what you want. With that said, however, the following should be true:
1) "race" type headers will not have EGR or AIR provisions, which you have on a 98. Its up to you whether you keep these provisions or not. If you do then you will retain OBDII compliance for sure. If you don't you will clean up your engine bay a little, but you will have to remove the codes or you'll get an SES light. To my knowledge there is no performance gain either way. If you want a direct "bolt-in" then you probably want the street version.
2) If you go with an ORP you will need O2 sims to avoid codes. The O2 sims will trick the PCM into believing that the catalytists are still there.
3) If you can, see about getting the optional merge collectors too - that should get you a little extra performance.
Hope that helps. <img border="0" alt="[cheers]" title="" src="graemlins/gr_cheers.gif" />

Re: QTP headers Should I order emissions or race style? thanks, very understandable and well put! and yes I do plan on going with the new merge collectors, by going with the race version I would save about 100 bucks but will it take longer to install? therefore costing me more?

Re: QTP headers Should I order emissions or race style? oh ..another thing about the codes that will need to be removed... LS1 edit can do that can't it? once I get the headers, cam and MAF installed I will be getting dyno tuned using edit so can I take care of that then?
Re: QTP headers Should I order emissions or race style? Yes, with LS1Edit you can remove the codes and since you don't have emissions testing you will be fine. The installation won't be any harder without the AIR and EGR, you'll just have to get some blockoff plates.
