locking will only change how it turns.....
15/41 = 2.73 ( hwy only no drag race)
13/41= 3.15, not much better.....
you need 4.11 with stock engine or 4.56 with real race.

thanks for the reply
4.11 and 4.56 they will give great acceleration but what about top speed?

You could bolt the mufflers right to the collectors but don't plan on listening to your radio or your passengers while driving. And putting the exhaust pipes down you're going to blow up a lot of dust/dirt that will find it's way into your car. Moving the mufflers farther back will make the interior a liitle more "accoustically pleasing" as well as having the exhaust exit out the tail end of the car, where having them turned down shouldn't cause any issues. Some people have them exit just behind the doors but I've never had them like that so I can't tell you the pros/cons.

I like the first one. But if you're going with the 4.11 you'll need something that will pull into the 6000 range. I'm not sure what you have but 3.73's would be good with it.
