It's funny to me how everyone goes for a huge collector and 3" pipes just because of "big is best"....when in actual fact, tuning the headers to the engine is what is more sensible. I opted for a smaller header tube (1-3/4") with standard 3" collector, and on my engine is runs very well on both street and the Dyno. Only making a shade over 400HP, and I don't care...what's more important to me is having an engine that is reliable and runs well without coughing, spluttering and wheezing every time i drive the car.
I'm going to make a better video than this....but listen close, and this is on the older spark plugs (before I changed to Autolite 86)....
