Fubar231 Posted January 19, 2011 Report Share Posted January 19, 2011 So im looking to purchase a 3" electric cutout here soon and don't really know whats better than what. I was going to just get a jegs electric one but then noticed how nice the QTP ones were. Anyone have any experience with them or any cutouts they would recommend in general? Heres the QTP one im looking at. http://shop.quicktimeperformance.com/cart.php?m=product_detail&p=36 Thanks Quote Link to comment Share on other sites More sharing options...

They sound neat if you have headers, but I think they are pretty ricer if they are not useful. Quote Link to comment Share on other sites More sharing options...
Fubar231 Posted January 19, 2011 Author Report Share Posted January 19, 2011 Well im running the stock exhaust , longtubes and ORY. Just going to put the cutout there for when i need it cause the stock exhaust is going to bottleneck the shit out of it. I also remember seeing a dyno chart of a bone stock ls getting around 12whp from a cutout being put on the stock exhaust. Quote Link to comment Share on other sites More sharing options...
KillJoy Posted January 19, 2011 Report Share Posted January 19, 2011 I had dual QTP 2.5" on the Marauder (supercharged). It went from Long Tubes to Cutouts, to the Stock Front Cats, Rear Cats removed, then to the stock H-Pipe (modified to fit) then into the stock Mufflers and tips. ~30 RWHP/TQ was gained from what I recall in this application between being opened and closed. :thumbup: KillJoy Quote Link to comment Share on other sites More sharing options...
pontiacfreak142 Posted January 19, 2011 Report Share Posted January 19, 2011 like wagner said, the hp you make, the better it will workand if you dont make enough, depending on how far forward you put it, it can hurt performance. Quote Link to comment Share on other sites More sharing options...
Fubar231 Posted January 19, 2011 Author Report Share Posted January 19, 2011 I was just going to put it on the Y after the longtubes and ory, because the stock exhaust will bottleneck it. Ill do what im gonna do, haters can hate. I was asking if people recommended any cutouts, not if they think i should put it on my car or not.

Nickey4271647545519 Posted January 19, 2011 Report Share Posted January 19, 2011 Lots of guys over on Team Chevelles dont like the QTPs due to them having plastic gears and you'll often find you have to replace those gears. Quote Link to comment Share on other sites More sharing options...
CRed05 Posted January 19, 2011 Report Share Posted January 19, 2011 I was just looking at getting a pair of cutouts too after seeing someone gaining 30awhp on a car with a similiar setup as mine. A lot of people seem to like QTP. also http://dmhperformance.com/ecutout.htm Quote Link to comment Share on other sites More sharing options...

Thats not good. Do you know what cutouts they switch to or run instead, or any that don't have plastic gears inside them? Quote Link to comment Share on other sites More sharing options...

CRed05 Posted January 19, 2011 Report Share Posted January 19, 2011 Doug's have ones that don't have a flapper valve, so it's less restrictive, plus its stainless. http://www.jegs.com/p/Dougs-Headers/Dougs-Electric-Exhaust-Cutouts/1282659/10002/-1 Quote Link to comment Share on other sites More sharing options...

Not saying if you should or should not, just trying to help you make an informed choice. Something that I wish people would have done for me in the past. You can call me a "hater" if you want, I could care less. You might see a drop in TQ from the loss in back pressure, but you should also see some HP. I know alot of f-body guys use the QTP stuff and seem to like it. If I were to put one on that would be what I would use. I would take a look over on LS1tech and Camaroz28.com for some good info.

I know exactly where your coming from and thats why i do so much reading online about parts before i buy them, i just get annoyed when i ask for information about a part or something then a bunch of people just chime in saying dont do it etc. Not saying you were but i was just getting that laid out in the beginning of the thread lol Quote Link to comment Share on other sites More sharing options...
Richard Cranium Posted January 19, 2011 Report Share Posted January 19, 2011 Any advantage to opening the cutout partially to increase flow, but no drop back pressure too far? You might be able to run it on a dyno and figure out a good compromise between flow and back pressure. Quote Link to comment Share on other sites More sharing options...
Linn1647545492 Posted January 19, 2011 Report Share Posted January 19, 2011 I have a QTP cut-out on my car and in the last 5 years QTP has rebuilt is twice for me. I picked up 40 rwhp NA over the stock axle back exhaust on my car (this is when my car made 441rwhp with the cut out open) Quote Link to comment Share on other sites More sharing options...

AJ Posted January 19, 2011 Report Share Posted January 19, 2011 why don't you spend the money on headers and a tune first. if your just wanting to ricer your camaro than go ahead with the cut out. Quote Link to comment Share on other sites More sharing options...

2 Sweet Posted January 19, 2011 Report Share Posted January 19, 2011 I have a QTP cutout on my bolt-on Camaro. I dare anyone to find me another f-body with the same mods that makes more power without a cutout. It has been proven that an LS1 f-body with longtubes will make more power with a cutout than any aftermarket exhaust. Mine has been on there for years, I open and close it all the time, and it still works perfectly. Quote Link to comment Share on other sites More sharing options...

CbusBusa Posted January 20, 2011 Report Share Posted January 20, 2011 I had a Race Ready cutout on my 98 TA and the screws for the motor kept falling out and the motor would fall out. My brother put a QTP on his 00 TA and I know he's had it rebuilt a couple times. We both ended up taking the plate off and just leaving the cutout open. Jacking up the car to fix that thing constantly gets old. Quote Link to comment Share on other sites More sharing options...

I've heard mixed reveiws on which ones will give you the least trouble. Quote Link to comment Share on other sites More sharing options...
Nitrousbird Posted January 20, 2011 Report Share Posted January 20, 2011 I had a DMH cutout, and after going through several (under warranty), I ended up with a QTP. It is a 3" (at least it fit my 3" cutout - I got it free for promoting QTP on a different message board), and was awesome. I stopped using it after I swapped to 3" true duals, as the car is too loud without bypassing the "mufflers." I'd have to dig it out of the basement, but I am sure I still have it, am willing to sell it. Not sure if I still have the switch or not, and it is just the unit, not the weld-in part of the cutout. PM me if interested. Quote Link to comment Share on other sites More sharing options...
