Get rid of it. I'm getting rid of mine and just running an amp to my speakers to save weight. That and stripping the trunk.

 

So should i go 25% or 43%? cuz i have a stock factory speakers and radio.

 

Eh its really up to you. I've heard the major power difference is the actual reduction in weight on the crank not really under driving accessories. I don't know if its true, but if it is there shouldn't me more than a 1-2hp difference between the two. If rpmoutlet has changed their service I say go for the motoblue 42% kit, every little bit helps even if its only 2hp lol.

 

I got the mach stereo system with the 42% pulley's and I'm fine.

 

Thats not really an aftermarket system. But yeah its been tested you'll be fine with the 42% I'm just saying that I've heard the real gain is from the reduced weight on the crank on necessarily all from under-driving the accessories.
