    What exhaust problems have you seen/expereinced/heard of with the ORD doubler and no body lift?

    I'm under there looking and it doesn't look like it will work. Do i just chop it and leave it for the exhaust shop to fix?

    Any help apprecaited.

    I just used a stock y pipe that went down the drivers side and widened its throat to match a 3 inch tube. I put in a 3 inch hi flow cat and a magnaflow 3 inch muffler. I am very impressed with how well it breathes. I think it is better then my true dual 2.25 with cheap turbo mufflers. I hardly had to bend at all. I just had an exhaust shop bend me 1 "S" bend for behind the muffler so that I could run it up and out to exit directly below the frame between the gas tank and the stock exhaust hanger on the frame there. I removed the bump stops and the middle of the 'S' runs directly through where the middle of the the bump stop bracket used to be. I flanged both the muffler and cat with 3/8 inch thick 3 bolt collector flanges so I can remove both with just 6 bolts apiece. Could send you some pics in a couple of days if you want. Hope this helps.

    See Zakk, I told you. /forums/images/graemlins/rotfl.gif Don't listen to me though. The 3" single exhaust down the driver side like I told you is the ticket to your troubles. Now I know it is going to cost you but then again, what hasn't? Rita gave you the go ahead on the whole doubler deal and if it means new exhaust then so be it.

    but on top of that, I don't really want a 3". the way I go through transmissions is flat out scary. I don't want to be having my exhaust redone each time I blow a transmission.

    Well Zakk, if you think you need to drop the exhaust just to replace a tranny then you are having the wrong guy do your exhaust. I have a single 3" exhuast down the driver side and it does not interfere with removing my tranny or T-case. Besides, I also had the muffler shop put in a flange so I could remove a portion of exhaust if I ever needed too.

    I have a 3" single and it isn't even close to the tranny, the passenger side goes forward and wraps around (underneith) the shallow part of the oil pan where it connects with the drivers side and goes back.

    I suspect his problem is long headers where the collector is past the bell housing. With shorty headers it should be possible to clear the tranny with the Y pipe. I just want to find a way to run the exhaust down the outside of the frame, there is just too much crap inside...

    Pulling the tranny is not a problem, used stock exhaust manifolds and a stock y pipe. the exhaust does not interfere at all with the tranny or t/cases. 3 inch for a single exhaust is just fine, and on my truck is a very clean install. The whole setup cost me about $120. I could have done it for about $90 but I bought about 8 feet of 3 inch exhaust tubing that I don't need (did not use), so if you need it let me know.

    i was messing around with the cut pipe, and I think i can make it work with duals. i'm going to try to get the rig down to a exhaust shop tomorrow morning after I get the shift linkage problems figured out.
