[Kolak]

Christmas is fast approaching and Santa Kolak has been pondering what to put on special for the holidays. This year I thought I'd do something I have not done in many years, and that is to conduct a "power buy" of my Kolak Exhaust upgrades with special discount pricing.

I've been offering custom exhausts for the Jeep ZJ, WJ, XJ, and TJ for 13 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!

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.

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.

no LJ's???

I never have made tailpipes for the LJ - there's not much demand. If, however, we can get 5 or more people who want an exhaust, I can make a batch.

Many of you have been asking for stainless steel mandrel bent tailpipes. I've decided to make a small batch of 3" tailpipes for the WJ and ZJ V8. Those are the only applications I'm making for now because of the cost involved.

The stainless tailpipes will be available for a $75.00 upcharge.

Hey Nick,

I'm sure this is probably covered many times on the various forums, but what exactly do you get when you buy your exhaust system, and what all is involved with the install?

Do you get Cat, tailpipe, muffler and tip? Assuming you go with a stainless muffler, like Magnaflowr, would the stainless tailpipe make your system 100% stainless?

Is this something that can easily be installed without going to an exhaust shop?

Thanks.

[Kolak]

If you need all the information, PM me your email address and vehicle information and I'll send you the information specific to your Jeep.

If you got the stainless Magnaflow, you'd have a 100% stainless system.

Something I neglected to mention -

Layaways are available. If you don't have quite enough cash to purchase the system at the discounted price by the end of the year, I will be happy to arrange layaway/installment payments. That way you're locked in at the 20% discount.

Merry Christmas everyone! And thanks for all the orders! There's still 6 more days to jump in on the sale pricing. PM me if you'd like an exhaust for your Jeep.
