Yes it did stop the smoking. I put it in and then left it till the next day. I cold started the next day while looking back out side. It just puffed very little when i did start it. The next day after, nothing. Just clean exhaust. I definately have increased power and MPG. Before i was just almost getting knocked in the seat when accelerating hard. Now, my CVPI is now how it supposed to be. Balls.
1998 CVPI, 2001 CVPI Grille, Stock size Motomaster SE tires, Sony Explode Deck, K&N Air Filter. Got hit and fate undetermined. Will edit this when I know details.
