Hi guys, For those with higher horsepower and stock manifolds, I now have some test pipes with no Kats in them for a direct installation with no cutting, or modifications. They are stainless and will bolt right up to the stock locations.

We have the no cat off road race versions for $350 for the set


They are a drop in kit, just pull out your stock section and put this section in.

Boost drops about 1-2 lbs, and you wont have to worry about melting your stock cats during your hard runs. Also going back to stock is easy, as you just bolt them back in when you need to. No cutting is required, they are a perfect fit.

They work with catbacks as well as they bolt right into the stock cat section. So no worries on compatibility.


For those that want them, call or email me and i will get them to you asap!

No, these only bolt up to factory manifolds.

If you want to cut out those on your kooks, just buy 2 feet of 3 inch tubing and 4 3inch exhaust band clamps and cut yours out.

yes you will, you will need to modify the tune to not freak out with them in place. If you have a custom tune, it should work just fine.

I want! Calling now.

For the offroad version w/o cats, you will need to have the rear O2 sensors turned off in your tune or you will get a CEL.
