I installed this system on a high-mileage car, mating to a Saab/Remus system which had been installed 6 years earlier. Installation was straightforward, although I did need to install a gasket betwen the new down pipe flange and the old Saab/Remus flange to prevent leakage. A gasket is not necessary if installing everything new.
I love the sound! A gentle burble at idle, silent at cruising speeds, and an earth shaking roar above 4K RPM's.
This pipe is a work of art, a true pity that it gets hidden out of sight beneath the car.
