Question Which will be louder?

I'm looking at two different options for exhaust systems on my 3100 SFI V6.
The first is running 2.25" piping with a CatCo catalytic convertor and a Flowmaster 50 series muffler.
The second is running 2.25" piping, the longest glasspack I can find, and a Flowmaster 40 series muffler (no cat).
Keep in mind that I need to keep the sound level to a minimum but still want the added performance from an aftermarket exhaust system. Pro's and con's of each option maybe? The second option will the cheapest of the two, but I'm really pretty open to ideas.

Is there smog checks in Wisconsin? Do you have yearly inspections on your car? Here in Oklahoma we got rid of all of that so now everybody just chops off their cats. Just and idea about not spending 100-150 bucks for a cat. Also I think the 30 series Flowmaster is the deep toned muffler for the big blocks. Try strait pipe to a single in and dual out 30 series and getting dumped under the bed with two / 3 inch around pieces of pipe about 8-10 inches long. Sound good!

My freind did about the same thing on a 6 cylinder ranger. Very nice.

Nope. No smog laws in good ole' WI to deal with! I guess that's one perk to living out in the sticks!

glass packs will be loudest and louder still when you blow them out. like it real loud? i've heard to gettem hot then run a hose up there and all the glass will blow out next run. never did it though as the possiblility of water getting up to the heads scares me. i guess one would have to disconnect the exhaust from the headers/manifold first to be on the safe side, and then you'ld be dealing with really hot pipes and nuts. could be the person that told me that had never tried it either. i think old glass packs are too damn noisy on long trips

For the non-loud--- 30 or 50 series. 50 series is the quieter version of the 40 series. and the 30 series is the deep tone. and the 8-10 inch long, 3 inch tip helps with the tone without killing the Flowmaster sound.

Try it with out the mufflers! the cat will tone it down a lot.A lot of the new pick ups around here are running just the Cats and tail pipes most sound very good! And you can allways cut the pipe and add a muffler if you don't like.
