Just wondering if there is a vendor that makes a set of aftermarket "headers" for the FJ80's yet? These would replace the factory exhaust manifolds and really would allow the engine to breathe much better. I've searched around on the net, but have not really come across anything. I found someone on eBay who appears to manufacture a set in Austrailia for older Cruisers, but, there is no real picture of the part, just some CAD picture... What about hi-flow catalytic converters or larger diameter exhaust piping? Anything avaialble for the FJ80's? Sorry if I'm asking "performance oriented" questions for a vehicle that is normally used for daily puttering or trail riding... but my mind is performance oriented being a Mustang Enthusiast... LOL! If there are headers, hi-flow cats and larger exhaust piping, just utilizing those pieces alone would really allow the FJ80/FJZ80 engines to perform better and more efficiently instead of being restricted as they are with the stock OEM exhaust setup.
