"A friend let me use a lift .the old system took longer to take off then the new one took to put on. the old system was one piece and had to be cut in order to remove.The Heartthrob system came in three pieces an only took about 5 min. to instal. This is not a loud system my neibor said it sounds good. I think so to." —Timothy P from Mansfield, CT bought a Heartthrob Cat-Back Exhaust System for a 2004 Jeep Wrangler.
"Installation took under 2 hours by myself, no issues, easier when you cut off the old exhaust, use some WD40 to ease off the rubber exhaust hangers. I had to take off the scrape plate holding the transmission up. Looks great and sounds good. Hoping not to sound too loud, but not bad. Gives a little bit of extra power, haven't had a chance to check mileage. Looking at installing a cold air intake to compliment." —Franklin S from Velarde , NM bought a Banks Monster Exhaust System for a 2004 Jeep Wrangler, Non-Unlimited, 4.0L 6-cyl. engine.
"If you are looking for a nice tone that isn't over the top, this Banks cat back is perfect. I have noticed a small increase in throttle response and power. Not a huge difference, but it is there. I'm also getting 1-2 mpg better gas mileage so far. I'm sure this will all improve as I replace stock components up to the headers and the intake down the road.
Worst part was getting the old one out. If your truck is a few years old don't waste your time trying to get it out in one piece, do yourself a favor and grab a sawzall. After the old one was out, installation was very easy." —Chad K from West Mifflin, PA bought a Banks Monster Exhaust System for a 2004 Jeep Wrangler, Non-Unlimited, 4.0L 6-cyl. engine.
"Looks great, makes my jeep sound really throaty, everyone asks me what I put on it to make it sound that good, and it was a pretty easy install, it was harder to take the stock muffler out than it was to put this one in" —Drake M from Andalusia, AL bought a Banks Monster Exhaust System for a 2004 Jeep Wrangler, Unlimited, 4.0L 6-cyl. engine.
"I PURCHASED, WITH FREE SHIPPING, A BORLA EXHAUST FOR MY 04 JEEP WRANGLER. I DIDNT EXPECT TOO MUCH OF A DIFFERENCE IN THE PERFORMANCE OF MY JEEP BUT, WOW, WAS I WRONG!!!
I LOVE THE LOW RUMBLE WHEN I START HER UP AND I'M GETTING BETTER FUEL MILEAGE AND PERFORMANCE.
I WOULD SAY THIS WAS A VERY SMART PURCHASE. BORLA EVEN PROVIDED A TURN DOWN CHROME TIP BECAUSE I HAVE A TRAILER HITCH.
NICE GOING AUTOANYTHING FOR CARRYING A GREAT EXHAUST SYSTEM LIKE BORLA!" —Jeanne R from Middletown, VA bought a Borla Exhaust Systems for a 2004 Jeep Wrangler.
