    Default Considering switching up exhaust...again.

    Hey y'all!

    I'm thinking about changing the exhaust on my Silverado (regular cab, short wide bed, 4.8L V8) once again. It currently has straights on it and before that it had a Flowmaster 40 series. I love having straights on it, but they've developed a terrible rattle from all of the vibration that seems to be non-fixable. Does anyone have any suggestions of what system I should try next that will still be loud enough to rattle windows?

    Thanks!

    Here a post of my exhaust, pics at bottom

    Magnaflow 14inch oval DI/DO 2.25 inch pipe ( its nice when you pick up your muffler and can see straight through it! )

    Though i wasnt going for the loudness i got, i can tell you that it sets off a many of car alarms just idling through parking lots. You can defiantly feel the rumble in your seat, however it has a bit to much cab noise for me which i may fix by getting rid of the turn downs and extending it out the back.

    Thanks everyone for your replies, I'm not a huge fan of Magnaflows. I haven't changed anything yet, I'm still rocking the straights. I may just leave them on until I trade for my 6.2L...I love the sound of them too much and can't find anything that makes me happy enough to commit to them.
