Cool, thanks guys,
and thanks for the pics too.

Those Lanes systems look good but I got to custom fab. mine due to the SPOHN torque arm.

i think after all my looking im going to stick a bullet or a xr1 borla shaped bullet on the end of the y pipe and call it quits for now.. the catback rattles, the cutout rattles... nothing i do seems to work tho ive got 3/4 inch clearance b/t all pipes and anything else lol..

I have the Mac's now and actually I've decided that, for my application, it's easier to just get true longtubes. Don't get me wrong, I love the Mac's but it's not nearly as difficult to get TD's for Pacesetter/Hooker headers. I'm actually buying a 2.5" x-pipe off of another member that is made for LT's and if I ever decide to change to Mufflex or anything similar, it'll be easier in that respect as well.

My Mac headers with hedman true dual X pipe are in my sig. I have switched from the bullets to Borla XR-1s in the last month and don't have any new pics with the borla's on but the sound alot better with a more "tuned sound" such as a mustang type sound.

Here's one way to do duals with a Spohn TA:



Kinda crazy looking, but it worked well... We've also done them running parallel together on the passenger side of the DS - which looks better, but may even be tougher to do. Not an easy fab either way..

I would recommend using a Dr. Gas X. I picked up 24 rwhp - and even more torque in the mid-range over a custom 3" Y with my Macs. Macs make excellent power with a good set of duals.

Good luck with your system and it will be worth it!
