Default Howe Racing Mufflers
Hey guys I'm thinking of redoing my sidepipes on my 460 Superformance. Originally I was going to have my heads ported and have the car dynoed but may do the sidepipes first. Just what is involved in changing out the SPF mufflers for the Howe's and what size ID and OD do you recommend for the Howe's.
