I recently installed a "Kolak Exhaust" on my 2000 Jeep Grand Cherokee. This kit consisted of Magnaflow Hiflow catalytic converter, a Flowmaster 50 series muffler and a mandrel bent tailpipe. I had done a lot of research on this kit, as it seems to be fairly popular. The kit is advertised as a 3 inch exhaust, but the muffler I received only had 2.5 inch inlets and outlets, while the cat was 3 inches both ends. I had been told to tell the mechanic to cut the old exhaust off at the y pipe, but the muffler shop said it was illegal to do that. So my current setup runs from the y pipe through stock piping to the 3 inch cat. The shop welded on new holes to the muffler so after the cat the pipe remains at 3 inches. The sound is amazing, loud with my foot in it and tasteful at highway speeds. Drone is next to nothing on the road. I have been asked if I have a Hemi under the hood several times. I have a 2011 Challenger with the 5.7 with true duals and flowmaster 44s, and they do sound very similar to this 4.7. Overall I am pleased with my exhaust, I just wish I knew a little more before I bought this. I could have just bought the cat and the muffler and had the shop give me duals from the muffler back. Oh well.

Pros: Quality, price, service
Cons: None
Recommended? Yes

Comments: This is the best exhaust kit you can get for your WJ. Best parts available, from flowmaster and magnaflow, the tubing is perfect and fits just good in my WJ.
You will have a converter, muffler and tailpipe, all 3 inches.
Competition cat back kits are 2,5', and more expensive, without converter.

I didn't use the tip (yet), I like the sleeper look better than this shiny tip, anyway, I may change my mind someday, so I keep it.

The sound is great, not too noisy for highway and street use, but really nice when you rev up.

Performances seem a bit better, in a matter of acceleration more than horsepower, but I actually didn't check this seriously, so I'll leave it to the ones who did measurements to say what it gives.

Nick from Kolak is helpfull, quick and efficient, great service, worldwide (I'm European)

Anyway, I'm very happy with my exhaust

Price: $425.00
Pros: Was able to get the muffler installed and the 4" tip. Feels right to have mostly 3" instead of 2.5".
Cons: Muffler alone did not have a change to the MPG or HP that was noticeable, just a better sound and air flow. Need to do the Cat myself.
Recommended? Yes

Comments: Nice sound, actually sounds like a V8 now, not too loud but definate change to the normally quiet tone.
Working on getting the Cat installed.
Nice looking Tip on there too.
