Pros: runs strong up to redline
Cons: bitch installing driver side

equal lengths on a SN95 are a pain in the a**, but my car now pulls hard all the way up to the redline. Before I could just feel when to shift, now I have to check the tach or I will bounce off the limiter

Pros: great flow
Cons: idividual flanges tend to move after some heat cycles, really cheap coating

these headers on my 1986 Mustang showed an instant improvement in power and fuel mileage, however, the tubes tend to move after heat cycles, so bolting them up again after 80,000 miles was not an easy chore, and I had to bend the pipes to make them fit on my new engine. A solid, 1 piece flange would improve my rating, also the HTS coating can be scraped off with a fingernail

Pros: Shifts the powerband up
Cons: Installation sucks, bad instructions.

Installed these on my '94 Mustang. The installation took up the majority of a weekend. Instructions didn't mention I had to remove the upper manifold and the brake master cylinder, then bleed the brake system for the driver side header. I scratched the s*** out of my Edelbrock upper before I realised this So much for the pretty powdercoat finish. Also scraped a lot of the HTS coating off of the driverside header.

Once we finally finished installation I burned an ignition wire on the maiden voyage, so now I'm running on 7 cylinders, when the engine is warm, until I recieve my replacements for my FMS wires

This was caused from the shape of the equal lengths, they're much more likely to burn ignition wires so if you're installing these and you don't already have looms, get some!

Pros: Helped my GT breath alot better.
Cons: HTS coating comes off very easy

Have these headers bolted to a Pro Chamber nice power gain. I paid a performace shop to install them and even they had a tough time. I thought my GT would sound much louder with these headers. I too buned some wires because of the. The number 3 and 7. I had to shave the boot on the plugs to give them some clearance. I haven't been able to get on it yet because of the wire issue and now the EGR tube on my Pro Chamber got disconnected and now car is back firing.
