Saw a deal for a topspeed exhaust with 3" piping. I know I'm a noob but is this to big to run without any other major mods yet. Had dual 3's on an old chevy with a built 350 so I noticed the lose of low end power there. Would hate to buy this and have it be the same deal on the z.

 

You wont really in a z because its 3in single on a 3.5 if it was 3in dual it would be a different story.
