I don't know, Phoenix, if you like the sound of a V-8, which it appears you do, I think you'd like the UEL rumble. I find it pretty addictive if achieved through the right, high-quality exhaust pieces. The key for someone of my advanced age is to find a system that only really rumbles when you're on it, but quiet when rolling on the highway. The last WRX I had (a 2007) was like that -- perfect. It had UEL exhaust manifold stock, mated to an Invidia Q300 catback, which is their 'quiet' system. I see that the Q300 is available for the Gen1 86s so hopefully they come out with one for the Gen 2 cars, which in any case will work great with either UEL or EL headers.Appreciate the explanation. I do like regular 4 banger sounds better.
