I got a 1987 Trans Am GTA with the 350cc TPI does anyone know any headders that could fit my car with out major modifications???
I do have some custom headders i bought for a 350cc but im not sure if they fit my car since on the manifold each side seems to have 4 metal lines that screw to the manifoild. The headres i bought done seem to have any conection to thoses lines.

350cc would be a little small, I understand you meant 350 Cubic inch, well anyways by far the best headers you can get for our cars are a set made here by Dyno Dons. They are the best and the easiest to install in my opinion and they look great.

Those "custom" headers won't be emissions legal.
Hooker 2055HKR are made for your car with only one modification required - cutting a leg off of the AC compressor brace that bolts to the exhaust manifold.
TGO member Dyno Don also has great headers available.

Search this exhaust forum for "dyno don headers" and you'll see all the threads and the pics of his product.Originally Posted by Dany89

The four metal lines in the manifolds you speak of are the AIR tubes. Being in California, your headers must have those or you will not pass the visual smog check. Dyno Don's headers have those, and if you bring the car up to his shop by Angel Stadium, he could install them for you too.
Send him a message for more details.

Go to the very left and click on "Dyno Don". See the second line that says, "send a private message to Dyno Don". Click on that and ask your questions to him. Prices depend on what you want. He usually responds fairly quickly.Originally Posted by Dany89
