Good idea to changed out the TR55's every 10K miles or every spring... If you let them go long enough they will let you know when they had enough with poor running, flashing SES light etc...

And for the exhaust... How deep is your wallet? You will never max out a single 3" system at your curent mod level or even with heads.

The true duals will give it more of a trumpety sound too and cost alot more.

the reason for exhaust is realy for a better sound than anything.. i evntually want to put a super charger on it but thats not going to happen for at least 2 years..

as for the plugs i guess i will be changing them soon as they haven't been done since the cam was put in. will the tr55's be fine? i think speed inc put in some copper type plugs im not sure..

Yes NGK TR55's FTW.
