If I get any gains from the TD's then that will just be a bonus. Weight?

Plus the entire cost of all the materials will easily be covered by the sale of my Borla. So there will be little out of pocket for materials. Plus it has been fun to do.

Update:
Well I cant have the dual cutouts in that cavity under the right rear seat. The tuck up in their tight but the drive shaft will hit the pipes when the car is on jack-stands and the rear end drops. That wont do.
I have relocated them closer to the front where the cats would go if I decide to install them. So the way it works now, I can have cats and no cutouts or test pipes with cutouts.
Holy **** this has been a lot of work. I have about 6 hours roughing the pipes in with another 6 hours fine tuning them to fit the desired way. I ran out of L bends so now I am dead in the water till Monday. All thats left is to fab the pipes from the muffler output to the tips. Then its off to TIG all the joints.
I also ended up not running the left side pipe under the panhard rod like the Bassani due to the mandrel pipe radius not being tight enough. I ended running it along side the right side pipe through the factory location above the panhard rod. Took hours to thread that needle but got er' done.
I have also managed to use the factory mounts for all mounting points. Check out the pic of the right side muffler mount.
I did fire it up to hear the sweet music. Man this thing sounds fuggin awesome with no rasp and pop at idle like what I had before. It has a very deep tone like what I was looking for.![Thumb](https://ls1tech.com/forums/images/smilies2/thumb.gif)

Looks like you stayed with the magnaflow exhaust parts. You will not be dissapointed.
Deep muscle car sound without the annoying pop and crackles of borla or the restriction of a flowmaster. Best of both worlds IMO.

Yours may actually sound deeper then mine because of that, which is sick since the bass note from my idle crawl is literally enough vibrations to set off car alarms in parking garages...no throttle needed! The exhaust thumps hit your stomach like 15" subs

I used to love glasspacks but now I am a huge fan of magnaflow.

Not counting the e-cutouts, around $500.00 for the stainless pipes, stainless accu-seal clamps, magnaflow muffler, magnaflow x-pipe, stainless dual oval tips and dynomax cutouts.
The sale of my Borla catback and my ORY's has easily covered the entire cost of the TD's again excluding the high price of the e-cutouts.

I only have 1/2" clearance above and below the pipes at the TA mount. I am going to have everything mounted so snug that those tight clearances should not be manageable. I also had to cut the middle leg off securing the DS loop to the Midwest TA mount so right now there is only one leg holding the loop on. I will find a way to get a new second leg welded up once the exhaust is done.
I will post new pics tomorrow of the whole thing completely fabbed up under the car.
