I love the exhaust, no regrets. I'd be happier if it were bigger though because I have other plans for the future, that would be even better if I had a bigger exhaust. Maybe I'll upgrade, we'll see. I've had people tell me my car sounds like a Subie, and I absolutely love the sounds of those Boxer motors.
Yesterday I actually saw this RHD Impreza wagon that sounded just awesome. I really want to look under the hood to see what's in it, I smell a bit of sleeper in it, lol.
And if you get the HiBoost kit, I guess that means I'm gonna have to push my projects forward sooner!!!!
BTW, I'm almost ready to do a 5 speed swap too, haha. Just need a clutch, starter, and a few other little things. None of this will be happening until atleast next summer though, when I'm done school.
