Axelback was no issue fit wise.
So ive been driving around for a week or two with this thing. It's awesome. I love the sound of it starting up in the morning. My neighbors not so much, while the car is warming up my neighbors might be a little grumpy, but once the idle drops down its fine having it idle in the driveway at 3:45am.
Driving, this sounds mean and I love it. We did a trip from Portland to Seattle and around 60-65mph it sounded like a slight drone. Once I got it up 70-75 mph I could cruise all day and it purrs nicely. I'm driving from Portland to the Lake Tahoe area next Sunday. 10 hours of driving straight I'll give you an update.
