I have run both the exhausts shown on my 2L motor and have decent torque from about 3,000 rpm.

The factory sport 1 exhaust was VERY loud - so much so that I was worried the police would come after me. Like Harlan, I wanted a quieter exhaust for the street without the cost, complexity and weight of the factory system.

The street exhaust consists of modified stainless steel 904 type equal length headers into a modified stainless steel 914-6 muffler.

For those people interested. I am working on a small run of 692 exhaust systems. These will be as close of a match to the original as we can get it including the rare welded clamshell exhaust manifolds.

Years ago I was ticketed for excessive noise in my 587. Th officer said he could see me. Coming on the db scale long before he saw me and the car. Miss those days

I will only warn that the 4 cam is extremly sesitive to the rxhaust back pressure not enought and the motor loses alot of low-end power. Alan The Stable.

Be very careful about the exhaust. Some of the loud one will make you lose much of the low end performance. Alan The Stable/
