what engine do you have?
if you want pro street? you have a lot of work to dolbz 2007 .I plan on having the work done .I do realize there are a lot of things to do and modify.Just want to make sure the people doing the work know what there doing.The first thing i guess is the tranny work.Im seeing a lot of good stuff here and cant wait .Im planning on a 6 month trek of doing the stuff i want done.The $$$$ are gonna be high im sure but for what i want it will be woth the wait.
