Anybody else running a kolak 3" exhaust?

Ordering my exhaust from him this week getting 3" with magnaflow large case. For those who are running a 3" on their 5.2, what was your overall satisfaction rating with his product? Does it preform well? How was fittment? Specifically for those with a magnaflow how does it sound, does it drone? Was there a dramatic drop in TQ off idle? Was the gain noticeable in daily driving or more when you "get on it"? Thanks!

I'm a little surprised that you opened this thread as you and I have had multiple, lengthy phone conversations where I've answered everything in great detail and with my customary detailed appraisal.

I assured you there's no loss of low end torque, discussed fitment, discussed diameter, discussed muffler choices and drone, power gains, you name it.

But anyway,if you search "Kolak exhaust" on Google or Youtube you'll find answers to most all of your questions.

Here's but one thread you can have a look at:

I ordered my system from Nick and got it installed this passed week, 3" Mandrel Bent Tailpipe, MF High Flow SS Cat, FM 70 Series and the MF 3" rolled tip. This system sound sooooo sweat!!! I also ordered all new control arms and when the UPS truck came to deliver them, I had to move the Jeep and the driver said, "That Jeep sounds really good, never heard one sound like that before."

Very, very pleased with this system and he was so easy to deal with. Thanks Nick!!!
