I'd just be scared it would be hanging down like crazy cuz there's very little space to work with in terms of swiveling the motor itself down there

Leaking is a good possibility, but there are things you can do to prevent and help them seal better.

1) If you live in a winter state, don't run it in the winter, the salt will kill them.
2) Remove the cut out from time to time and clean off the carbon deposits, that is often what can cause the leak.


Here is a vid of my wagon on the dyno with the cut out open. The video doesn't do the cut out justice though because the mic isn't that great.

Just a question for all who may know. I'm thinking of rockin' a electric on my new setup. Strictly for dyno and track purpose only LOL of course.

Just me thinking... with the cut out in place and OPEN, while the regular route fo the exhaust bypassed, how much flow is still flowing through the regular route? Would it be more benifital for the cut out to be open, and then the regular route to be CLOSED?

I guess like a dual channel cut out that would close the regular route and open the cut out. I danno if there's anything out there like that?

Or does the exhaust flow natrually flow more to the closest exit?

Exhaust will flow towards the path of least resistance. Some of the gases will still flow out of the tailpipe, but I'd say a solid 90% will flow out the cutout. The dual channel cutout setup is a novel idea, but in the end it may be more work than its worth, and might even flow worse than just the single channel. If you want an optimal setup, seeing you have an '02, ditch the rear O2 sensor and mount the cutout as close to the turbo as you can.

Yeah I plan on running it at the bottom of the DP, running right beside the EWG dump tube. Exiting behind the front passengers tire through the side skirt.

Im interested in putting my cutout there but just wondering if anyone can think of any reasons not to put it there??? I currently have a cobb catted downpipe if that makes a difference. Seems like it would be hidden enough to make sure it doesn't scrape over anything such as speed bumps and at the same time open straight down and therefore shoot flames to the ground...Any input on this setup would greatly be appreciated...thanks

I love my cutout there. No clearance issues like others have when under the car, closer to the turbo, I don't get any soot build up under the car there either.

I don't have a single negative thought of putting it there.

Geez I had my hands on a used QTP cutout but since the midpipe it came on didnt fit my car I sold it back.... I just should of cut the cutout out of the pipe and gotten it welded into my d/p where Xcelr8to1320 has his. I bought it for really cheap also.

I understand that it does however make more of the noise come from the front side of the car and fumes are heavier in this location. For these reasons and the lack of knowledge on the performance of the cutout, people have been placing their cutouts in the midpipe area of the car.

This makes sense to move sound closer to the actual exhaust and have the gases exit towards the rear but it NEGATES THE PERFORMANCE out of this mod and turns the cutout to SIMPLY A NOISE CONTROLLER.

I would be very interested in seeing someone post up dyno sheets or any numerical information regarding their midpipe mounted cutouts. There has not been any substantial evidence regarding the benefits of this location as compared to placing it near the downpipe.
Update: with cutout mounted at midpipe, I gained 3 psi with it open.. Tomorrow I will be welding it directly after turbo and will post numbers after next tune! But it seems that even at the mid pipe it is affective.. I mean.. Less back pressure is less back pressure..

Default The Official Cutout Thread

With the cutout right behind the turbo, It seems to make very little difference.. Besides in cabin noise level (duh it's in the engine bay).. I think that since it's so close to the turbo, less exhaust is heading out the cutout because it's all getting forced out of the turbo.. Any thoughts? Maybe also it's because my ypipe is facing downward so all the exhaust seems to be getting forced down the back of the ypipe into the dp..

You're fine, so long as you dont mind the underside of your car covered in soot.

Back in action! Finally got around to ordering a new motor after the old one died.




The original motor "protection" was complete garbage and split from the heat. It was very poorly designed, but the new case is much more protective. Hoping this one will last longer.

Old motor vs. new motor:

Badass. Ive been thinking about upgrading my motor to these new ones they got. Let me know what you think. I completely agree with you on the protection of these new motors versus the old ones.

The internal parts themselves are all the same, just a new and more useful case. The case isn't sealed though at all so I just used some RTV to seal the case where the wire comes and and where it bolts to the cutout. I did have to file the case tabs though because the hardware from the old cutout was too short.

On the DMH website it asks for a size of the cable or wiring, and I'm not exactly sure what size to get. Any ideas?

Has anyone put a cut out on the axle back. I don't want to ruin my dp and midpipe because they are after market. But I hav a stock axle back that I custom welded to a 3" midpipe. I want to put a cut out on the axle back since its already screwed up.

What type of cut outs are u running from qtp? Slim or not?

If the axleback is welded to the midpipe, why not just put the cutout on the midpipe?

My dp I would like to leave alone. The midpipe/resonator is a perfectly fine 3" HKS part from my Carbon Ti HKS cat back. I would like to leave it unmolested and have only my axle back molested that has a welded 3" flange. Just incase I sell the HKS catback.

Im really debating about selling my aftermarket exhaust and funding this. how much would it be for a company to weld in the exhaust if I had the downpipe off the car aka run stock for a few days and let them weld it in my 3 inch exhaust. I really like the fact about stock noise and really annoying loud exhaust. I live on base and I know some people dont like how loud the 3" catback is.
