Default New Muffler on a 04 RST?

the muffler on the truck is pretty eat up right now, the pipes just sit in it, its not even connected lol, so i wanted a pretty loud muffler but i wanted the flowmaster sound so i got this,...it might me a little loud lol



Super 10 Series 409S Stainless Steel - Single Chamber mufflers. Intended for customers who desire the loudest and most aggressive sound they can find. Because these mufflers are so aggressive, they are recommended only for off highway use and not for street driven vehicles. These mufflers utilize the same patented Delta Flow technology that is found in Flowmaster's other Super series mufflers to d eliver maximum performance. Constructed of 16-gauge 409S stainless steel and fully MIG-welded for maximum durability.

Super 10 Series Muffler, 3.00" IN (C) / 2.50" OUT (D): ea, 409S Stainless Steel

If you still have cats they won't be super loud, should sound pretty decent.

Boog, I have a regular 40 series on my truck and when I put it on, it was quiet. The old muffler qwas rotted though so the holes made it loud. Honestly I don't think it will be too loud. Maybe perfect with the cats. Let me know when you get it on. I want to hear. Is the exhaust pipe on your truck rotted away too? I think I need to replace the entire piping on mine.

allright guys, UPDATE!~~~~

everyting was eat up underneth passed the y-pipe, hell even the tips started rusting throuh were the weld was on the pipes...

had the tips tack welded, new exhaust pipes and muffler from y-pipe back put on, look good, no more rattles(from being loose),..................but DAMN it, its no louder now than it was, not know if its from being used to the muffler being eat up and louder than normal or what??, .....now it does sound a "little" deeper when i get into it, but i was expecting a LOT louder.................SO...........LT headers, off road y-pipe, and cat delete is on its way here real quick..

i will have a vid here real quick so you can see.......
