2012 Jeep Wrangler (JK) aftermarket muffler

Re: 2012 Jeep Wrangler (JK) aftermarket muffler
Just some information on my 2011 Wrangler 2 Dr.
I have the Gibson dual tip exhaust muffler. I installed it myself in about 20 minutes.
I had heard that it was noisy on the highway which they do have a constant drone at highway speeds and are loud going through the gears.
I had also heard that it was too wide open and did not create enough back pressure which hindered the motor.
With these two concerns, I fabbed baffles that sit just inside each of the tips. I drove and adjusted the baffle holes and angle attitude until I reached the [imo] best sound and performance. It took a few tries and a few kms for the computer to regulate and checking over a one month period but I have noticed increased fuel economy, acceleration and smooth running.
It now has a nice growl, no drone and a noticeable [again IMO] performance gain. I did install a CAI but have since taken it off as I noticed no difference to the stock filter. I will probably get a K&N filter eventually before replacing the stock just for economics more than performance. Although I do not think the extra air flow will hurt.

Re: 2012 Jeep Wrangler (JK) aftermarket muffler
Hi there I'm a complete newbie to the jeep world. I'm in love with my diesel cummins but I always wanted a jeep. I have a 2012 wrangler unlimited sport. What do you guys recommend for air intake and exhaust? Some guys where telling me just to go with a drop in air filter (K&N) since the stock air intake is water proof or something along those lines? Performance is what I'm going for now, maybe even L/100km.
