i was just wondering what everyone was running for exhaust on their 383's or 396's for exhaust? i have hooker long tubes, no cat, and flowmaster exhaust. i was wondering if it is too restictive or if i just shouldn't worry about it. It sounds good adn loud the way it is. thanks

 

Also what wieght of oil do you guys run in your motors. i'm currently running mobile 1 10W-30. should i try 5W-30 or is 10w-30 just fine? thanks

 

I would leave the Flowmaster on there and just get a cut-out. Good luck.

 

i heard cut-outs aren't worth it if you already are runnin no cats and long tubes? idk though

 

With a cut-out, you are not having to go through the muffler (or any of the catback, for that matter), which is the biggest restriction (especially with Flowmaster). Your 396 should see very good gains from a cut-out.

 

thanks for the advice. anyone have any suggestions about the oil?

 

ive always wondered about mufflers for big blocks.. so a muffie would restrict it pretty bad?
