So far, I really like them. Very similar to the Hookers from what I've seen.
Thats good news because Im also upgrading from MAC midlengths to LT's with 3in duals. What mufflers did you use, Im using Flowmaster single chambers. Im temped to throw a pair of cutouts right after the headers for track use.

I'm not sure Flowmasters would fit under there...

I personally would go with a better flowing muffler.

Get rid of the flowmaster and get a better quality muffler. You'll be glad you did!

This is the setup Im going with. The Flows fit under there. Like I said before, Ill probably throw a pair of cutouts on the collectors for the track.

I am running Flo-Pro Twisters. Got them from Lane. They sound awesome IMHO and not much quieter than a car with open cutouts... just better because they are deeper and without the rasp. The LT's/True duals set up is so free flowing that installing cutouts wouldn't be worth it. In fact, driving the car around on the street, I'm on the lookout for the Po-Po so I can lift off the throttle before getting near them (it's that loud).
