Wow no flameage on this kill. Thought for sure there would be someone raising the bs flag haha
Yeah Hemi's like exhaust upgrades but you gotta remember its not a real Hemi with Hemispherical cylinders. I know i have seen the inside of about 10 of them so far.

They have 2 spark plugs for each cylinder too so imagine what its gonna be like when its time for a plug change

I have already seen dyno's of an exhaust system on a Hemi and its suppose to add like 17hp. Can't remember what company makes it though.
