OBD II cat is $165

2-1/2" Stainless tubing and all hardware $420

You'd pick one of the following
2-1/2" x 14" long aluminized resonator $60
2-1/2" x 18" long aluminized resonator $65
2-1/2" x 22" long aluminized resonator $70
2-1/2" x 14" long stainless resonator $85

and then one of these
2-1/2" x 4" x 9" aluminized muffler $70
2-1/2" x 4" x 9" stainless muffler $98

I could do the system tubing in mild steel to save $$$ but it would
rust quickly.
When a cat is purchased with an exhaust or header there is a $25
discount.

I won't install a cat or header on a OBD II car, if the car has the
header and cat already installed then I will do the cat back install. The
above system is in about 9-10 pieces and requires a lot of tig welding
and therefore labor for the install will run about $350. This puts the
cat back total in a range of $900-$953 plus tax on materials. This is
right in Line with the Mugen system however this system will flow
better. If you bought the cat also it would be $140 due to the discount.

If you want to post this you can.

Thanks for the interest. I don't currently take cc so it would have to
be cash or certified check.
