sandwood Posted December 30, 2005 Share Posted December 30, 2005 I'm wondering if anyone on the boards has them or had them on a previous car, or has ever been in a car with one. you get the idea. nasioc has some info but not a lot. thanks! getting out of the legacy game Link to comment Share on other sites More sharing options...
BOXRPWR Posted December 30, 2005 Share Posted December 30, 2005 sorry to sound stupid...but what exactly do you mean by "exhaust cutout"? I had the QTP header on my LGT for about two months. No problems related to the QTP hardware. Took it off and resold it only because it wasn't working well in harmony with my bigger 20G turbo.

sandwood Posted December 30, 2005 Author Share Posted December 30, 2005 cutouts are outlets for the exhaust that can be welded into a DP or pretty much anywhere in the exhaust plumbing. they can be opened or closed using an electrical switch or in some cases using pressure to open a valve, i believe. see: http://www.quicktimeperformance.com/QTEC/ the advantage is you can run a stock-like exhaust system and then when you want added performance or sound, you can open, or partially open, the cutout and vent exhaust gases prior to either the mufflers or even prior to any cats in the exhaust. needless to say, they are very loud. getting out of the legacy game Link to comment Share on other sites More sharing options...
PGT Posted December 30, 2005 Share Posted December 30, 2005 The VW R32 comes with one from the factory. Rather, an electronic flapper that allows it to be selected for loud/quiet. I like the idea of using one....maybe put one in before the 'y' and split to a turn down? Link to comment Share on other sites More sharing options...
sandwood Posted December 30, 2005 Author Share Posted December 30, 2005 I like the idea of using one....maybe put one in before the 'y' and split to a turn down? exactly. some people do it in the DP, but I'd like to move the noise further back a bit, and just before the junction of the Y makes natural sense. putting it after a cat won't maximize power, but at least you wouldn't have to worry about flames jetting out under the car either getting out of the legacy game Link to comment Share on other sites More sharing options...

MDTURBO Posted December 30, 2005 Share Posted December 30, 2005 Hi Alex, I got your e-mail and will respond to it as well. I'm a firm believer in open exhaust The cutout will definately free up some more horse power, expecially the closer you get it to the down pipe. GM guys like myself and other ls1 boys on this site know the cutout is a sweet way to free up some horse power in n/a applications... but for turbo guys, the gains are two fold. QTP makes one of the most popular electric cutout systems. http://www.quicktimeperformance.com/QTEC/qtecphotos.php Definately the cheapest way to get full performance out of the exhaust without spending a fortune on a cat-back. flip of the switch go from stock to open pipe. :evil: -Rob 2012 Forester XT.

LivNLegacy Posted December 30, 2005 Share Posted December 30, 2005 liquidIQ has one....not sure if it's QTP tho....maybe he'll chime in... If you can read this, you're following too close. Click Me Link to comment Share on other sites More sharing options...
Guest Shaggy7 Posted December 30, 2005 Share Posted December 30, 2005 liquids was qtp i believe... and i think on nasioc he has a sound clip under txic. search for his screenname and posts. sounds good. Link to comment Share on other sites More sharing options...
liquidiq Posted December 30, 2005 Share Posted December 30, 2005 Nope, it was a DMH Performance. Got it with a Flowtech cutout. http://www.dmhperformance.com/ With the Cobb downpipe, and stock catback, they had to remove the resonator to install the unit. In the car, you can't tell a difference. Outside it a little more "tinny" but it all goes away when you open the cutout :) Link to comment Share on other sites More sharing options...

sandwood Posted December 30, 2005 Author Share Posted December 30, 2005 teamjordan - where in the exhaust did you have it installed? I guess liquidiq put it in the middle of the midpipe.... anyone familiar with the ones that slide a gate open, instead of using the rotating plate that dmh and qtp use (or do you call that a butterfly valve?)? getting out of the legacy game Link to comment Share on other sites More sharing options...
MDTURBO Posted December 30, 2005 Share Posted December 30, 2005 butterfly valve is the correct term, haven't heard of a sliding gate type. I have heard of a vacuum referenced cutout that opens under boost. 2012 Forester XT. Stage 2+ Retired from Racing. I used to build FMIC and more.

boostsr20 Posted December 30, 2005 Share Posted December 30, 2005 butterfly valve is the correct term, haven't heard of a sliding gate type. I have heard of a vacuum referenced cutout that opens under boost. Too slow and it would wear at fast. Especially if it will ever see snow/ salty roads. The VW R32 has a flap INSIDE the exhaust, not a cut out. A cut out would optimally be open before any cats in the exhaust stream. Link to comment Share on other sites More sharing options...
liquidiq Posted December 30, 2005 Share Posted December 30, 2005 Ive heard numerous stories of the QTP breaking, I would go with the DMH. If you look at QTP's website, I found no warranty for the cutout. DMH has a 4 year warranty. Link to comment Share on other sites More sharing options...
boomshnka Posted December 30, 2005 Share Posted December 30, 2005 Would EM be a bit tricky with this kind of setup? For everyday driving you'd want a stock map I would assume (or whatever matches your particular setup). I don't believe that you would be able to change maps as quickly as you could flip a switch though to take full advantage of having no exhaust. Is this even really a concern?

sandwood Posted December 30, 2005 Author Share Posted December 30, 2005 I don't think you need to worry about changing maps when you open it up. you would not maximize your gains without a custom tune, but you'd still see some benefits. getting out of the legacy game Link to comment Share on other sites More sharing options...
Xenonk Posted December 30, 2005 Share Posted December 30, 2005 QTP is pretty reliable, so is DMH.. I have seen both and they work just fine.. just dont go submerging your car in a large puddle of water.. I will be going with this route as well and probably bolt it up to either with the non-catted STi-type downpipe and do a 02 non-fouler on the cat, or just replace the stock resonator on the midpipe...

STi2LGT Posted December 30, 2005 Share Posted December 30, 2005 Anyone know anything about this cutout that opens up under boost: http://www.atpturbo.com/root/releases/release091004.htm Only problem is that mine would be open all the time....j/k:) Link to comment Share on other sites More sharing options...
liquidiq Posted December 30, 2005 Share Posted December 30, 2005 Map changes won't really be a concern. I expect that my tq curve just to expand a little to the left (tq on earlier). HP would be the same scenario. Link to comment Share on other sites More sharing options...
