if you don't mind me asking craig, how much did the exhaust run you?, they want 600 to do mine, and will not dump the exhaust in front of the tires like I want it done
I'm wondering if anyone has had a chance to Dyno these yet? I bought mine but haven't had a chance to install them yet. Craig, granted the heads are different, what fun did you have putting these in? Did you have to move the motor? What were you running before? I have stock manifolds in mine. Does anyone know if I'll need to move the motor to get them out? Here's a more interesting question to go with the rest. What do these shorty headers flow? What would extending the collector do for performance?
The only thing I can add: Had to raise the motor up an inch or so to install. Not hard to install at all. Had factory manifolds before. No need to move the motor to get those out.
help Craig, I'm trying to install the same headers on stock heads and I can't seem to get them in. I had to jack the drivers side up quite a bit to get it in. Now, I can't get the passenger side in by jacking the motor up due to "hitting" the headers on the driver side. How did you install yours? In what order? And, when you say you jacked the motor up one inch was that both sides at the same time?
I did the passenger side first....from the top. Then did the driver's side from the bottom. I lifted up the entire motor at the same time. It helps if you have a helper under the car. I also had all the steering off of the car at the time. Hope this helps.
i have a set of the Doug Thorley shortie headers for sale if anyone is interested i bought them put them on when to the exhaust shop and was told they wouldn't make it past the the aod transmission with the stock steering.
Did you have to do anything special to make them fit? Also do u have any pictures of them installed? I paid $475 with shipping so Im not sure make me an offer.
