Pretty easy little mod. Not loud at all...can hear the turbo a little more and best of all, lower EGT's.

Will see if I can get some audio and post it to youtube on Sunday.

Nice RollingRock, I put a turbo back exhaust kit on about a month ago and I noticed the truck breathes so much better with out a muffler or cat on the truck.

OK, so the resident / site engineer has to ask: Any difference in performance?

Well, I only have 3 miles on it thus far, but from what I can tell you others say, removing the cat will allow more flow but you will also here a tad more turbo, that openness will allow the turbo to spool quicker and I did notice the turbo did have less back pressure...mainly for me it will be about moving temps...lowering EGT's by 50 to 100 degrees is a good thing. I should also see a mild bump in mpgs'

Gonna go drive it in a few to hear it more.

RR, you should yank the muffler off just for grins and go for a drive. I can almost bet you it wont go back on when you get home.

Grey, I would love to however, my goal was to remove some restrictions yet keeping the noise down. I love the sound of the turbo back but if momma ain't happy, you know the drill.

I got to do this mod under the radar.

I know all to well what you are talking about but my wife actually likes the sound of it until it gets over 2500 RPM and starts sounding pretty snappy like a glass pack. I may put a muffler on it to get rid of the snap and drone if it gets to annoying but so far it tolerable and only really drones when I have the 5er on the truck.

Lets see if this works, pretty short and it was done on a total cold start.

Sweet!

OK, I've got to ask. How do you get in the right (passenger) side of the truck and do that?

Tom...what do you mean? All I did was stand on the KR "Nerf" bar and turn the key.
