??? for the Exhaust Gurus

I have a 4 banger and wanted to split the header for dual exhaust. I was just wondering the best way to split it as far as what 2 cyls would be best together. The firing order is 1-3-4-2

Well Mr. Ricer man. There is no point to split it at the header, even if you want to it would cost too much to do, or you would have to custom make it.

The best option is run a cat-back dual exhaust system either split after the muffler, or before the muffler.

Summit sells 4-2-1 headers for FWD ricers and I assume you could buy the headers and cut them right before the pipes go from 2 to 1.

if you had dual exhaust you would want to balance the pulses anyway, so after the collector split them but i fail to see the need to run dual exhaust on any 4 banger

87442lover, to start with not all 4 cyl cars are imports, Just like your 442 is figment of some Oldsmobile bean counters mind of what a real 442 was/is.4bbl carb,4 speed trans and a true dual exhaust. Many people on this board have the skill and tools to do "Custom" stuff to our cars, That is why we are here.

Dubz, Yea i dont really have to split it but I thought it would be a different sound. Just like when people split an inline 6 header. I have some time to kill as I rebuild my project car from the ashes of the recent California fires, right after I build a new shop. The exhaust is just an easy project for the "Shop Truck".

BWAHAHAHA!!!

And yes I know what a 442 is. My cutlass is 4bbl, 4 speed,and true duals thank you(or more like thanks to G-force performance)

You'll more than likely have to custom make it.
