You can go with the glass pack muffler form http://www.cherrybomb.com/products/, there great on price and yes loud, or you can go with the Super 10 Muffler 409S - 2.50 Center IN / 2.50 Center OUT - Aggressive Sound Brand:http://www.flowmastermufflers.com/index.php?cat=1 Mfr Part #: 842515.
"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 deliver maximum performance. Constructed of 16-gauge 409S stainless steel and fully MIG-welded for maximum durability."
Note:
Many people think that having the biggest diameter pipe is the best way to make power. Not true!
It is a fine line to reduce backpressure while maintaining good exhaust velocity. It is not about getting the biggest pipe, it is about getting a more efficient pipe diameter while maintaining exhaust velocity. There has to be a balanced design to enhance the maximum engine output, exhaust gas velocity, and sound. This is why it is important to get the correct size piping in order to relieve backpressure while maintaining thermal efficiency. ENGINE SIZE 300-350 CID / HORSEPOWER 200 to 350.
MUFFLER INLET/OUTLET Single Exhaust 2-1/2" to 3", Dual Exhaust 2-1/4" to 2-1/2"
Good luck and hope this helps and if you just want loud try http://www.racereadyperformance.com/
