New Cat Back Exhaust Option - all stainless steel.

[David Czarnecki]

Very Interested. I just want more sound, the Gren is too quiet. I'd order today if you had it available. Do you have a cold start video with your pipe on? Should sound better than stock on the cold start high idle. Thanks.

I am picking up the first batch of Cat Back systems tomorrow and they are for sale and shipping out. Check out the video from Friday. I can work with you on shipping. Feel free to email me as well. david@design-build-go.com

What’s the price point?

First 10 systems are shipping free in the Continental US. https://www.design-build-go.com/product-page/kooks-exhaust

$2,299. There is a lot of 304 Stainless Steel. No welding and labor most people could do it themselves.

This video has multiple driving conditions that you can hear the exhaust.

$2,400 plus tax because California as of September makes this attractive but aspirational add on.

It's $2,299, free shipping (first production only) and no tax because I am under the threshold required to charge for online sales. I hope that helps. https://www.design-build-go.com/category/kooks-exhaust

Fair enough, $2,299 and tax to California, 8.75% for me and another $100. to Baja keeps it on my "someday" list.

Thanks. Look forward to seeing your final product.

This is the final configuration. Has testing at multiple driving modes. The exhaust sounds best at spirited driving conditions and is quiet if moderate driving conditions which is ideal if you have clients or the family cruising around.

Thanks. I have an engine light on and now a clicking noise in the steering column.... dealer picking up my Gren tomorrow so we will see how these get resolved before I do anything else.

Hi there, I'm interested as well but not very technical minded on exhaust. Is this just for a better sound, or are there other real world benefits? Tougher off road, better gas mileage, more power, etc?
