Ok I'me about to order this list, but one item in question is the Underdrive Pulley.My car has the shaker 1000 system and I am wondering if running the underdrive pulleys is going to affect my voltage?I do notice with stereo base pounding lights do dim slightly with each big base hit.Also with all the new sufisticated electronics the car has i am wondering that the drop in voltage might affect Fuel pump,Spark,and all the other things that need full power.When i was racing GrandNational,s I remember people having battery problems with underdrive pullies.

 

Not neccesarily realted...but, you should check out crossroadzdirect.com for your MagnaFlows. They've got the Axle Back set for 399.95

 

I have had the Steeda UD PUllies for a few months. I also have the Shaker 1000 and use it quite often. I have had NO issues.

Go for it

I have had no issues either, on the Steeda underdive pulleys

 

Are you aware you can purchase the C&L CAI & Predator bundled together from RPM Outlet for $629.95? I personally have the C&L CAI and Predator.

Let's see that's $140.47 less than you quoted. I'll split the difference with you.

PS: I am not cheap - just very thrifty!!

 

Sean Hyland Motorsports pullies are exact duplicates of the Steeda part and cost $169.00 instead of $249.00. They are a quality SFI product that performs great.
