Default Guys that have made there own true duals

Well I can't really find an exhuast that I want so I'm thinking of making up my own true duals with a box of mandral bends. I'm just wondering how many bends you guys have used to do this. I'm only going to about the front side of the rear axle but it won't be dumped. Anybody out there made up there own exhuast?

Are you going to do a H pipe or x?

i used the summit univ Xpipe setup. then a little extra pipe to connect the driverside collector up. on most ls1 headers the driver side angles out towards the left of the car. so i had to get a minor bend there. i also had to run a minor bend down directly off that collector. the flowtech headers tuck up really well. you can't run straight back off the collector due to frame interferance.
so i had to angle down for the first few inches, then bend in to meet up with the leg of the Xpipe.

here is the down bend


and the whole setup, you can see the front bend a little

Don't need to weld that great. Just tack the peices were you want and then take them off and weld or have them welded.

Here is pic of my home made TDs.. My main goal was to make it tuck up really nice. This was before I welded on some turndowns onto the mufflers...



I made mine from the 2.5" Flowmaster U fab it exhaust bend kit and a couple Sweet thunder mufflers using an H pipe setup. Sounds great, its silly loud at WOT lol, and I have plenty of clearance as well. Here is the lowest part of the exhaust.

sixvi6, you wouldn't happen to have a sound clip would you? I was thinking of running sweet thunders.
