Santa Kolak Announces: Kolak Exhaust 20% Off Sale!
It's December already so Christmas is coming up fast. This is my fifth year offering this special pricing, so it's a holiday tradition for Santa Kolak to put his Kolak Exhausts on special for 20% off regular pricing during the holidays.

I've been offering custom exhausts for the Jeep ZJ, WJ, XJ, and TJ for 15 years now as I'm sure many of you know. Thousands of Jeepers all over planet earth are using my exhausts on their Jeeps, and this will be a great opportunity to join the crowd and save a bundle.

For this sale I'm offering fully 20% off my regular prices. So you'll save upwards of $75.00! I've held the line on pricing all year long, so if you missed out on last year's sale you won't pay a penny more.

The most obvious benefit of a properly constructed free-flowing exhaust is more power and of course a healthy exhaust note. You'll also be pleased to know that fuel economy gains are also significant - I've received endless reports over the years of gains from 1 mpg to as much as 2.5mpg.

All of my exhausts follow a very important methodology:

1) The stock tubing size is increased to what is correct for the engine displacement. In the case of the 4.0 I6, the correct diameter is 2.5". For the 4.7, 5.2, and 5.9 V8 engines, 3" diameter is best for maximum power and efficiency.

2) The main catalytic converter is replaced with a high flow unit. The typical stock Jeep converter flows just 270 cfm. My recommended Magnaflow high flow converters flow 425-450 cfm depending on inlet/outlet diameter. These are the highest flowing ceramic converters on the market, the winners of the Hot Rod magazine converter shootout test. I also am now offering California legal converters as an extra cost option.

3) The muffler is replaced with a free-flowing unit. Here I recommend Flowmaster mufflers, specifically the 3-chamber design. These have no rpm sensitive drone or resonance.

4) Last up is the tailpipe. Here I have my custom Kolak Performance mandrel bent tailpipes. Mandrel bending allows tight radius bends with no restriction.

I have setups available for the WJ, ZJ, XJ, and TJ. Just send me a PM with your email address and vehicle information and I'll send you detailed information and pricing. :thumbsup:

And for those of you with either a 5.2 or 5.9 ZJ V8, I've had Doug Thorley produce a limited run of their tri-Y ceramic coated headers. Here's a photo to tempt you:

Just the Kolak Exhaust is on special, but I have great pricing on the Thorley headers while they last.

I have these headers and can attest to their quality. Definitely a good buy!

I need a tail pipe that I can connect to the Dynomax muffler that will clear the Hidden Hitch trailer hitch. The stock cleared the Hidden Hitch just fine; however, I had to have the trailer hitch removed to install the Dynomax CB exhaust. I took it to another mechanic for him reinstall the trailer hitch, and he ended up cutting the tail pipe and welding another piece of exhaust pipe to angle the pipe away from the hitch and now it is making contact with the tire when they are booth caked with mud. It broke the hanger weld and now its dangling. Will your tail pipe fit like the stock and clear the hitch? If so, can you pm me a price for just the tailpipe? Thank you! By the way, I had the performance cat installed that I bought from you, and it seems to have improved the performance and mileage.
