Re: Shorty Headers
I'm real happy with the install on the Hedman shorties. I only had to take 1 engine mount bolt loose and jack up the drivers side of the engine 1/2 inch. I KNOW that sounds scary but in fact it was SUPER-DUPER easy.
Performance-wise, i don't know yet -- but talking to some TPI gurus the shorties offer the right amount of back pressure to help performance.
So, i give a +1 to the hedman on ease of install.

I had a set of hedman shorties on my car and noticed absolutely NO performance difference before and after. I attribute that to the 1 5/8 primaries (IMO too small for any 350 or larger engine) and the 2 inch y pipe. If I was going to waste my money on shorties again I would get a set that are 1 3/4 primary with 3 inch collectors and then have a 3 inch y pipe made with a flowmaster merge collector in it. But, I will never own another set of shorties so that's out of the question.
