Has anyone out there done any aftermarket mods (pipes ect) to gain power/speed? I have the 2005 370hp speedster, and I am looking to do some mods. Also has anyone out there added the second battery to power up radio ect?

I had my Seadoo dealer put in the second battery, $250.00. As for aftermarket, Solas has impellers, 11/19 for the 310's and 12/20 for the 370's. I may also do the power filter and the vortec impeller. My shop (Jet Trendz) did the Riva Stage 3 on my GPR, and they have done several stage 2's on the Rxp's Rxt's, so I trust them on my Speedster. He can't wait to try it, if I go that route, it won't be till after the season is over.

gtoys - youve got 370hp and your looking for more????..........

Do not want to sound like a wimp, but my Sportster has plenty of power for what we want to do. What I would like , however , is a quieter muffler for those times we are crusing at 20 m.p.h. or so.
Any ideas would be appreciated.

you could add some sound insulation to the trunk lids underside and the engine bay gunwales.

Thank you, but I believe it is exhaust sound from behind that we hear.
The engine compartment is very quiet.
