    My w9 with 3406e got stock exhaust prev owner said he cut out the mufflers on inside but its still pretty quiet, trying to figure out if their is still enough restriction to justify putting straights on

    Go for the straights, 8 inch preferred. You won't regret it.

    Just put some hi flow mufflers on it, you will get the same milage and performance as straights and you won't get ticketed for not having mufflers and it will be alot cheaper to put on hte hi-flows than buy 8 inch straights.

    Walker Mega Flows are straight through.... The question you really need to ask is why do you want to lose your hearing ?

    Im 51 yrs old and the straights are music to my ears specailly when I have the windows down. I also have a high power sound system in my truck, woofers, components, tweeters, amps. Now that I think about it, when Im at home and my wife asks me something, I ask her why she's yelling at me :director:
