Had Lous install a performance exhaust today in my Jeep Grand Wagoneer. They shoe-horned my after-market y-pipe onto my manifolds, were able to re-use a 2 1/2 cat already on the jeep, which flowed into a 2 1/2"single in, single out Magnaflow 5x8x18 stainless muffler.
Deep, throaty tone, very quiet at idle, but pick right up when i step on it. Makes my worn out 5.9 liter sound great, but more importantly the straight through design gives the old truck noticeably more grunt, from standing to passing.
They beat my closest estimate by $300 dollars! Friendly guys working there, Marc is a honest guy. I might never roll up my windows again! Love that sound!
