Now you can sell the Kooks over the axle section and ofset some of your costs.

That is a real nice setup. It's too bad you had to modify the Kook$ dual system to tame it down. I think half your problem is your motor though. That thing is a beast so most of the exhaust solutions for us may not necessarily apply to your combo.

Omg, you cut up a kooks TD system?!?! You did a great job but that's an expensive system to cut up. Where did you get that merge/Y ? Looks nice. Is it stainless?

It is a Vibrant and is very well made out of stainless....everything in this system I now have is stainless.

I didn't want to cut up the kooks TD but honestly the system sucked and I hated the car with it. The HP difference is not enough to make much difference that I can tell.

I own a professional business and almost every time I'd pull into the employee parking lot there are clients I drive past in the customer lot. Sometimes clients are coming to us in a time of great sadness. The way the car was with kooks TD it left a bad impression on non car people, so I wasn't driving it.

No doubt the beast motor is the main issue, I do think though any motor that truly need the Kooks TD is going to be putting out some serious power and it does very little to muffle the exhaust. There was even one guy saying that the TD didn't meet the sound requirements for his local drag strip.
