If you MUST use glasspacks, get some preforated ones (little holes). The louvered GPs are absolute crap. The louvers stick into the exhaust stream, cutting down on flow, and thus any gains you wanted from the new exhaust system. Effective pipe diamater is usually cut down one pipe size using these POS's. Turning them backwards does nothing except make them louder, they do not flow any better, and in some cases, worse.
I would not take a pair of louvered GPs if someone PAID me to take them.

I think im going to turn it around today, Redhots were the cheapest I could get at the time, and i dont have the money to spend on exhaust right now. Once I get some cash saved up Im going to either get Stacks, or 3 inch true duals with super 40 mufflers.

Allied glass packs are the best. They are actually classified as resonators but the flow as well as magnaflow & flow master- when you compare size to size. Most any muffler shop will have them and range insizes from 10" to 38" IIRR. Nice deep rumble, nothing obnoxious and very well built...cost runs on avg $20-$40 each depending on the size.

On a 6.9, single 3" wouldn't but I was under the impression that you meant dual 3", that would be pointless. Even with a diesel you still wouldn't be making use of that size pipe.

I had a set of the purple hornies that bolt right up to the header collector. They sounded great, except when you have a cop behind you who's probably wondering why it's taking you 6 miles to get up to 40 mph because you are afraid to open it up and get pulled over for illegal exhaust. Eventually they get aggraved and just pass you.

LOL, weird, they usually pull me over in my cavalier. Probly has somthing to do with the fact that A: it takes about 6 miles to get to the speed limit and B: they can't see a muffler, only a 4"x24" Chrome tip. That and pretty much the only time there is one behind me is when I'm out @ 3 AM on the weekends(Not drunk but they check because I'm going so slow while they are behind me)

45" will be fairly quiet but will have a decent tone. I did a fairly extensive tuneup on an '80 F-150 with a windsor that had dual 2" and 45" packs, sounded not too bad, couldn't hear it inside but sounded nice out back.

I resemble that remark...
I have dual 2 1/2" in & out 45" Thrush GP's behind my 390, Jones cam,Sanderson headers...They sound.....GOOD. I did not hook up my cd player for along time bacause the motor was sweet sounding enough.
