I just put my header and presilencer on today, started it up with just those on without the power pulse muffler and she was loud. Anyways, I was wondering if you are supposed to run a tube from the heat shield up into the air cleaner still or just take that flap in the air cleaner right off. Actually what happened was i took the flap off, and then realized i might need it. Is it necessary to have on????

 

that tube is to heat up the air when its cold, you can get rid of it

 

Sask get pretty cold. id leave it. I modifed the heat shield so just the little nipple part was attached to one bolt of the headers, and then used a hose clamp to clamp the other end on the header.

So long as there is a small gap for air to get in, its fine. Best to have it closest to the headers so it will draw the hottest air. I needed to get a new hose from canadian tire, but it was only 5$. i can get you the part number and pictures later if you want.
