QTP Cutout Hey I have a stock 2002 WS6. If I get a magnaflow cat-back and QTP cutout, will that bolt up to my stock headers? Is this a good combination for a stock setup? Any advice or suggestions welcome!
I have dual cutouts in my Y, but the better place is in the I, where you described. Could be wrong, but I'm almost certain welding is required. So, if that's not for you, take it to an exhaust shop and SHOW them where you want it. Should be very cheap work, like 1 hour. If it's electric and you have an M6 (maybe A4 too), you can run the wires up through where the shifter is. I'd tell them you'll do that.

i have a QTP cut out straight pipes and flowmaster muffler.. i have a vid in my sig that will show you what it sounds like.. keep in mind this is a crappy set up but i've ben saving for headers and duals which im ordering next week. I have the cut out placed before the muffler and its pointing down.. most will do this but you have to tell the people where you want it.. im not sure how they did the wiring i didnt watch, but most people get there switches put inside there arm rest console. mine is placed kinda near my right knee.. its hard to explain id have to upload pics which i can do for you if you PM me..
Yes it will bolt up to the stock exhaust. If I remember correctly, the stock pipe is 2.75" and most people end up getting a 3" cutout which will weld up just fine. I have the same combination as far as catback and cutout. Actually if you end up getting a catback the I-pipe is 3" so it ends up being the same size as the cutout. Here is a picture for reference. Not my car but looks exactly like that

Yes, there is welding. Take another look at the picture I posted earlier and you can see that the cutout has to be welded to the I Pipe. It doesn't take long, the exhaust shop I took mine into charged me $35 to weld it up. As for sound, here is what the cutout will sound like when it is open

The cutout is going to sound deeper and louder, but I can tell you that it's not overly loud. I haven't closed my cutout since I had it installed, but if I were taking the car on long trips I would probably close it. Also, do a search on how to install the wiring for the e-cutout. It's not hard but you should at least get an idea of how others have done it. Good luck.

Has anyone tried using the Dynomax cutout or any other that has the ends stepped? It looks like the ends will slip over the ends of the exhaust pipe. If you were to use some stepped band clamps on both sides that seems like it would hold and keep you from having to weld. It looks like it would allow you to take it appart also a lot easier.

I understand what you're saying, but at the same time it would be kind of pointless to remove the cutout. If all you want to do is run the exhaust through the cat-back then you just close the cutout. The cut-out gives you the option of either. As for the clamps, it seems like if they came loose they could rattle a lot and you'd have to get under the car to tighten them. Probably not a big deal, but at the same time it creates another argument for welding rather than clamping.
Also I was looking at the ease of getting the exhaust out of the way to be able to work on other things under the car if need be. I have had some experience with these style of clamps on other vehicles and have not had an issue with them loosening. The area was just a little better supported with hangers which would have made it less prone to sagging (I would think).
The SS catback is stainless and flows well/quiet enough for me not to put on an aftermarket catback. I already have a DMH e-cutout waiting for the cutout to be installed.
