If you think you are going to modify your 300EX and you are interested in Sparks racing. Look up their website sparksracing.com and give them a call. They have a few exhaust options for the 300EX depending on displacement and modification level.

My dad says I can get some modifications for my 300EX for Christmas. So I'm lookin at aftermarket exhaust. I was wondering which one will give the biggest power gain for my 300EX;
1. Supertrapp IDS comp. sys.,
2. DMC's comp. sys.,
3. A Big Gun sys.,
4. A Duncan Racing Double Barrel comp. sys.
5. Or a White Bros. E-Series Pro Meg Silencer w/ a White Bros. Works Head Pipe.

I just turned 16 so I will be gettin a job soon so I'll be lookin for some other performance products. Also I heard that the 330 kits can make 300s run w/ 400EXs. Can anyone tell me about TC's 330 kit, and Sparks's 330 kit? Also, how would RCR's 352cc kit stack up against modded 400EX's? I'm plannin on starting mx racing in the near future. Any info given will be very much appreciated.
