I'm thinking about going with the QTP dual cutout package.
Question is...where would the best place be to install them? Right after the header collectors? Right before the x-pipe? Right after the x-pipe?
What do you guys think?
Current setup...MAC headers, Dr Gas x-pipe system, Dynomax bullets, turndowns before the axle.

theres no point in having cutouts if your not gonna have cats or mufflers. BTW i just got and xpipe put on and it sounds bad ***! i had headers, cutout, orp prior and it was just annoying loud, this setup is sweet loud. i had mine custom made to fit perfectly and assymetrically with 2 bullets and 2 turndowns. and with the hammer cam it sounds sweet <img border="0" title="" alt="[Big Grin]" src="gr_grin.gif" />
but if you really want cutouts anyway, id say right after the xpipe would be best looking at mine

What do you mean there's no point, it will be louder, give some more horsepower, and just another cool thing to have. I'm going to do this to somewhere on my FLPs, maybe they can install a cutout in each of the offroad pipes on that system. For you, I'd probably do them a little after the header collector instead of right after them because some people say air could come in and make the O2 sensor readings inaccurate if too close, so just move them back a tiny bit from the collectors, if you did them after the x-pipe, I couldn't see what the point would be.

If I go with a true dual I'm going to have dual cutouts RIGHT after the headers > X pipe > cats > mufflers
Don't bother if you don't have cats or mufflers though.

Yeah, I was thinking somewhere in the middle (after collectors, before x-pipe junction).
But also, I was thinking right after the x-pipe. With them positioned there, I could still get the faster scavenging effect from the x-pipe, and then wooosh right into the cutout.

Well... This is what I am running right now. 3" duals off the Grott LT headers, through the X pipe, to cutouts (on each side), to a pair of 3.5" thick muflers, that sound like a 30 series Flowmaster, actually quieter.
If you think you are going to put dual cutouts right after the headers, you are in for a surprise. You will loose alot of ground clearance. I'd be surprised if you made it longer than a week without ripping something off. I have it right in front of the mufflers, which ends up being right in the cubby hole on the passengers side, and on the drivers, the cutout would shoot right onto the fuel filter.
Needless to say, I have not uncapped the cutouts yet, because I need to fab up a cover to cover the fuel filter. Dont need to cause any fires.
When I get that done, I will test at the track.. After I get a rear end first..

00 sunshine: do you have pics? E-mail me INSSANE99SS@aol.com
As far as the cutouts go, I haven't done exact calculations, but i may tilt them to the side so that I have clearence.

No, I do not have pics, yet.. I will post them when I do. But tilting them anyway you can think of, is not going to give you the clearance that you need to mount them right after the header.
The problem is the drivers side pan & the way that it is formed. This is the lowest part of the car, and thus, any cutout there, would be forced to be lower. I thought of everything that I could, because I wanted to do it like that. But after having it up on the lift & looking & measuring, I ended up putting it after the X & before the muflers. I'm happy where it is at now. I just hope it works out when I get some heat wrap put over the fuel filter..

If you had a manual, that would be an option. Mine is an auto, & not enought room, imo. I felt better about having more clearance. But I also have my car lowered, so I try to gain as much clearance as I can.

He said not to buy a cutout off the internet and have it welded in because it could cause the v-flanges not to seal completley anymore. I'm looking for a shop that will do this, I think I might stop by Minekie tomorrow and see if they will. I'm going to show them the picture of the jethot coated cut-out on www.tbyrne.com 's site and see if they can do it.

In that situation, it would probably fit. You may have to put the drivers side cat on the second bend in the Y pipe. That might show from the side of the car though. Just something to consider.
Things are going to be more visable from the side.
