3" Exhaust Install

I finally found some time to install my new exhaust! I decided to remove the down pipe from the headers to weld on the 2.5" to 3" pipe enlarger. I kept the factory hanger that bolts to the transmission. I also welded the Flowmaster 70 and Magnaflow cat off the car. Kolak sent a hanger with the tail pipe but I modded it a bit. I wanted the u-bolt facing upward so the threads and nuts would not be visible. It didn't look very clean with them showing. I'm pleased to say that I have had zero clearance issues with the tail pipe. Its a tight fight but you can find that sweet spot! Overall I'm really happy with the sound. The muffler is still breaking in and it's definitely getting louder...but in a good way.

You should definitely get it! The exhaust note is great. There's some minor drone under acceleration between 2,250 - 3,000 rpm, but nothing obnoxious. It's amazing how well these motors pull through the rpm range. At interstate speeds I don't hear it at all. It runs very quiet while cruising around town. If you remove the downpipe from the headers to weld the pipe enlarger on be sure to give the nuts/bolts a thorough soaking in PB Blaster or similar. There's a weird flange nut that is a huge PITA to get off if you accidentally bend the flange! Take my word for it

Re: 3" Exhaust Install

My WJ spent most of its life in FL/GA so it is very clean underneath.

Re: 3" Exhaust Install

So, I am a noob and after some looking around I found that many people recommend Kolak... Where can I view this vendors products and prices?

Thanks!
