Nhp Install Update....nhp....is....installled!!!

Following has been installed:

5w-40 Castrol Syn

6 new Interpulse Plugs

NHP Full Exhaust installed

I can not tell specifically from driving on HP gains. I can say the back end broke loose like it never has before.

To me the sound is fine. if it gets to lound in the cabin all you have to do is go up a gear and it instantly quiets down to nothing. this is acceptable for me. but I also don't us the radio much.

try to dyno next weekend.

Old Beru Plugs
