Which ones have the least drone at highway speeds? I think I like the SVT1. Not to loud but louder than stock.
I had full Bassani on my Terminator and it sounded wicked but if you were to drive it anywhere for more than 45 minutes, I wanted to pull my hair out .
SVT-1 might as well be REALLY close to stock until you get on it. Actually...I'd say they're quieter than stock when just driving around. You really have to get in it hard before they start making any noise. Sound great outside, but deathly quiet inside just driving around. Virtually no noise at all until you start lugging it down in 6th gear under 1800RPM.
I'd also consider the Corsa if I were you, but I can't stand the way they sound outside.
I'm running a Magnaflow Catted X w/Bassani on my 04 (w/ baffles out of tips) and love it overall. It's "borderline" too loud, but not to the point I can't take a 4hr trip in it. Really doesn't drone at all with the X on it (compared to the bassani X it's quieter).
