it seems like i have seen this somewhere before. I am looking for something that flows as well as 3" i want to gain as much clearance as possible with true duals. i had 2.5" td for a while but want to go a little bigger as i think it will benefit the car.

Thanks
Scott

 

Dr. Gas has it in 2.5, 3, 3.5, and 4. they also have mufflers transitions, bends with transitions, and just about anything else you will need. If you want stainless Burns Stainless has it.

 

I think oval exhuast tubing would be a great idea for TDs, but I don't think 2.5 TDs is hindering you.

 

Spintec makes steel oval tubing
