GTV6 Exhaust Manifolds vs Headers
Since headers for the GTV6, that fit correctly and work well, are not now available in the USA ( Ricambi states that maybe they might make another batch) I decided to travel a different route on my 81's exhaust system.
We all know that Alfa cast iron exhaust manifolds are perhaps, amongst the best in the world, I decided that rather than squeeze a lesser system into the car, I would "prodify" the existing cast iron ones.
After being matched to the cylinder heads, I sent the manifolds to Jet-Hot Labs in Alabama for their standard inside-outside ceramic coating. Their standard color is silver. Turn around time was only a few days and the results were great. The ceramic coating has the the look of chrome plating but with a slightly less shiny, mechanical look.
The manifolds are hooked up to the small mufflerettes with the flex tubing. The twin tubes go straight back to where the resonator was. The twin tubes are then joined together by a "Y" which then goes over the rear axle to an Ansa rear muffler, with twin chromed exhaust tips. This work was done at Alfa Import Center, Ridgewood, NY.
The resultant sound is sporty to say the least, being bearable at speeds up to 70MPH in 5th. Full acceleration is an experience ! The sound has a slightly high-pitched tone, reminiscent of the traditional ripping silk sound of song and story.
This "sound" is of course aided by a Greg Gordon Intake system, J&E 11.5:1 pistons and Colombo & Barriani cams.
Thus for 1/4 the price of a first class real header system, I have a set of good looking manifolds that are now almost as efficient as that header setup.
