Wrangler SWB 4.0L engine; Borla Stainless Steel Cat-Back Exhaust System with single chrome tip and stamped Jeep logo.
Price: $656.88 Pros: Better flow Cons: Unacceptable "drone" noise at freeway speeds.
A "blaaaat" exhaust sound when engine rpm is stabbed/jumped on. Recommended? No
Comments: The Mopar product is made by Borla.
Increase in engine response wasn't that noticeable, exhaust note is terrible when the engine is jumped on. Had to add a resonator to get rid of unacceptable noise.
Price: $380.00 Pros: Shiny. Says Jeep on the Muffler. Sounded good, for a while. Cons: Poorly made. Inlet pipe separated from the muffler after only a year. Began blowing packing out after about 6 weeks. Recommended? No
Comments: Poorly made. Harder than average install. Muffler and inlet pipe separated. Blew the packing out.
Price: $190.00 Pros: Strait forward install. Good tone. VERY cheap compared to the other cat backs out there. Cons: Not as loud as other exhaust Recommended? Yes
Comments: Strait forward install. Good tone. VERY cheap compared to the other cat backs out there. It is not as loud as other cat backs but for only 190 there is nothing that will beat it for the price.
Price: $195.00 Pros: Cheap, noticeable sound but not annoying, stainless steel, lifetime warrenty. Cons: fitting to the existing mounts seems a little loose, like it might wobble a little over bumps, but that's it Recommended? Yes
Comments: Bought this for my LJ on ebay from a guy new in box with shipping for about $195. Great deal, I heard the actual muffler is made by Borla. Just be prepared to drop the skid plate as well as hack saws to cut off the existing exhaust (not to mention the rusted solid bolts holding it on).
