304 stainless pipe, mig welded with stainless wire.

thats not too bad. the H pipe could be designed a lot better and definately time for stainless headers if your going with stainless pipe.

and no offense, but all that money in the M9 and other suspension components and you still have stock stamped steel LCA's?

"Bluefirebird" that's a damn nice set-up. Where you at? I could use a nice system, lol!

I have finally finished the true duals project for my 1995 Z28. The entire system is stainless steel and was made from Magnaflow mandrel bent pipes.

Here are the specs:
Flowmaster 3" to 2.5" reducers
Magnaflow stainless (5) J-bends, (4) L bends and (1) 45 degree bend
Woolf aircraft (2) 2.5" radius L bends
Magnaflow dual in/out (internal X) muffler
Magnaflow X-pipe
Magnaflow stainless dual oval tips
Dynomax stainless cutouts
QTP electric cutouts
Lots of stainless Accu-seal almps

I designed the cutout pipes to be easily removed and replaced with catalytic converters should the want or need ever arise. Takes about 30 minutes to do this. Also the whole thing can be easily removed rather easily just like a catback.

All pipes are stainless MIG welded and ground smooth for a seamless look. I polished the rear pipes exiting the muffler to a very shiny finish as well.

The exhaust sound is deep with absolutely no signs of rasp, popping or machine gun sounds in the 2K RPM range like what I had with the old Borla catback and ORY pipe. The sound volume at idle, as well as WOT, is similar to any other catback. Definitely not overly loud unless you open the cutouts. Maybe this is due to the Magnaflow X-pipe up front and the internal X-pipe in the muffler. The exhaust waves should certainly be balanced with this setup.

Ground clearance is outstanding with the lowest point being ~5" off the ground. This is on the pipes just before they go over the axle. I have yet to bang a pipe.

I also managed to reuse all the factory exhaust hanger points to secure the new system. I only had to custom make one new hanger, just in front of the axle as well as the pair at the tips. There are also stainless O2 bungs welded into each reducer for easy hookup to the wideband O2 at the dyno.

Thanks to everybody who offered help and advice with this project. I could not be happier with the final results.
