I have pacesetter lt's and want to do a ORY. Should I open up then end to a 3.5 or 4? My future plans are H/C/I and spray later. Also, which muffler? I want something with a deep rumble and loud.

Thanks in advance,
Eric

3.5 or 4 is too big IMO... just keep it as is... 3 inch all the wall... thats more than enough for what you want in the future... only loud muffler i know is flowmaster.. but i recommend goin with a borla.. they sound nice and deep, dont have that awful drone when cruisin, and are loud at WOT

3.5 at most, but 3 would be perfectly acceptable. Besides, once you go past 3 not many shops can bend pipe any bigger, which means it gets alot more expensive.

Go 3.5 and get an aero turbine. As loud as a blowmaster but sounds way better, and not everyone has one.

Big case flowmaster 50 series 3.5" in/out.Its actually not that loud only at wot.The best part is there is very little rasp.
Or big case 22" borla 3" in dual 2.5 out sounds very good too.I would keep the cats somehow they really don't hurt performance too much.While taking them out limits mufflers that you can use and still sound good.
