Definitely less resistance. I think if he put some bacon in the aluminum foil it smell great and in turn prolly get a few more HP out of it
Funny.. the pipe part made me laugh..
back when I was racing my 87 K5... durring one race the pipe broke... right where the stinger starts (under the side plastic).. so I pulled into the pits... and only thing I had to fix it was... in the ice chest... I happend to have TALL guinness cans of beer... so... since I refused to pour it on the ground.. I quickly drank 2 of them... cut the tops and bottoms off... slit in half... and wrapped the pipe with them... 2 hose clamps later... I finished the remainder of the 75miles of the race...
worked good enough I left it on there for 8 more months... (hard to find pipes for the 87)
