So I go talk to a guy at 2 diff muffler shops. I tell both of em the same thing, not exactly sure what I want but I know the sound I want. Tell em I want that deep aggressive sound, but not too loud and not too quiet. One of them tells me to go with the Flowmaster Super 44. And eventually I need to get both of my cat's replaced (making it sound even better). The other guy says to go with a brand called Twister (never heard of it) says it has a more aggressive sound than the Flowmaster. The first guy also recomended a 10" Cherry Bomb or something like that. Now I'm sure these guys know what there talkin about, but I also know that they want to upsell as much as possible. Alright guys... I'd listen to yall before them... whats up with it???

Heres the sound I want............

that sounds like it has the stock system in it for that year.

 

Sounds pretty quiet to me

 

Flowmaster Super 44 would be an excellent choice. Chambered mufflers sound best on 6cyls. If your willing to put more bucks into it look into a Magnaflow hi-flow cat also.

Well you dont want to louden up a 6cyl too much
