Attention Jeeple: if there is anyone interested in putting exhaust on a newer Jeep wrangler with the 3.6 or 2.0 let me know. I'd like to try and make a jett-pack style exhaust out of curiosity...It would look and possibly sound similar to the slowmaster outlaw series kit but I feel like i could do alot better on the pricing.. Also ive always wanted to try side pipes with an x pipe underneath on a newer jeep if that interests anyone... shop: 605 493 6465 cell/txt: 605 228 5001 ...thanks...
