Might want to consider some PHP rear toe rods and using an SCT tune. The tune part depends on if you intend on dynoing locally or doing mail order.

Also, I'd suggest getting the MM IRS carriage bushings while you're there. They REALLY help a lot with wheel hop and keeping the rear planted.

 

if i was you i would go with the magnaflows insted of the flowmasters. magnaflows sound so much better

 

Are you sure you only want to go with a Spec 1? I'd consider something like a 3.

 

and are stainless steel. Flowmasters will rust.

 

i really like my magnaflow, it has a great sound and just that little but of a pop when you let out on it.

 

I considered the Magnaflow. If the flowmaster doesn't work out, maybe I will sell it and get a magnaflow instead.
Making the rear end more solid is the next project. These parts are just the beginning.
I plan to get sub-frame connectors, bushings, etc.
Ran out of money this round, that's all...
