its not terrible inside. i get more noise on the inside of the cab from wind noise then the exhaust.

 

got a free flow cat from napa for 190, and then 140 for a 4wd.com cat back system wit mufler and 2.5 inch pipes. it sounds nice for a jeep and around 2800 rpm it sounds badass.

 

Anyone ever used a dynomax bullet muffler? I have 2 of them on my other inline 6's and they sound sweeeet! But they are on manual trannys.

 

oh yeah, my $25 muffler was a thrush turbo.

 

DynoMax cat-back from quadratec for about 180 bucks. Not much louder than stock but has a deeper tone. EZ install

 

I've run a Dynomax bullet muffler on 3 different vehicles, Its also whats going on my jeep, Personally my favorite sounding muffler. As far as exhaust its all about finding a good shop, I learned the hard way, my first truck I got cat back split to duals and tips with no muffler and paid like $360. I found another shop locally and they did my Camaro header back custom made from pictures I brought in of SLP loudmouth on a newer camaro, All 3 inch mandel bent for $175, So thats where I go now. My Yota I made my exhaust myself cause no one could bend it tight enough so I bought mandrel J bends and made it myself

 

I got the 4WD Hardware 2.5" catback exhaust on sale for $110. My original cat had begun to rattle quite a bit, so I got a Magnaflow cat from Summit for about $70. I later opted to replace the cheapo 4WD turbo style muffler with a Dynomax UltraFlo muffler that set me back $90. Total of like $270 into it spread out over a year or two, kinda alot to spend on the Jeep but it sounds perfect now. Low and throaty, with a nice Buurrrrrraahhhh!!! exhaust note on full throttle.
