Cool Where to get 4" cutout?

Looking to finish up my exhaust. Going to cut the TSP off road y merge at the point that it is 4" in diameter. Weld a 4" intermediate pipe with a cutout and reduce down to 3" and go over the axle into a hooker Max flow. Just need to find a good source for the cutout.

I got my electric motor from a member on here, and got the actual pipe from Summit. The motor is a QTP and hasn't given me any issues.

I also got my QTP 4in cutout pipe from summit.

My Cutout is a DMH but they took over a month to get it to me, their website is deceiving as it shows all the cutouts with a cutout pipe yet they 4in costs more to include the pipe.

I used to have a QTP 2.5in and it worked flawlessly for 3+ years

DMH also makes high quality 4 inch electric cutouts.

Yea the only problem is you have to wait forever to get them. I have friends that have had issues getting them fixed under warranty as well. I wish I knew this before buying one.

But it does look nicely built lol

I just didn't see the 4" cut out pipe listed on either summit or jeg's, just up to 3.5". I will give one of them a shout and order what I need. Not looking for the electric portion right now, will probably do so in the future. I think getting the merge and intermediate matched up will make a big difference right now, since the merge outlet is only 2.5" right now. 3" would have been OK, but having it at 4" with the 4" cut out at the track will be kick ***. Once I get the exhaust finished, I am gonna try and setup an appointment to have a dyno tune done by Frost. I think that is gonna make the biggest difference in my ride. It was running rich before the header swap and now it is rich as hell.

I am not a dyno guy, but it will be nice to know what it makes and give a good guage on how it should perform at the track. Not to mention Frost is supposed to be the man, so I am hoping to find a few ponies in the tune.

Got the pipe, cutout and reducer ordered. Picked up a poly trans mount while I was at it.lol

Should be here mid-week. Hope to finish up by the weekend. Can't wait to here it, hope it doesn't sound too ghetto.

If you ever get an electric cutout have a turndown made for it...it will help. It'll be loud if you leave the manual cutout open lol
