Default MAC LT HEADERS & H-PIPE!!!

Just ordered and want to get some feedback on them and possible hp gains with current mods, NOS and N/A. Headers have HTS coating not ceramic.

They are a lot better than people make them out to be. I installed them my self and they fit right into place and they make the car sound better!

don't expect to much or you will be disappointed... as in power, it will have a nice sound.

You'll see 15RWHP or more from a full exhaust setup.

What size of shot are you using? It's kinda hard to even estimate...

LTs are probably one of the higher gain bolt ons, if u dont count s/cs and nitrous as a bolt on
