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.

You are talking to the wrong people then if they are suggesting that you need to keep backpressure to have better performance.

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.

Re: Shorty Headers

Don't be so quick to sell shorties short (no pun intended), we have cars here in So. Cal.
making 380-410 HP to the rear wheels w/TPI and shorties w/ 2 1/2" y into 3" collector.

PS w/ cats in place.
