First off, very very light. The welds were excellent and the fitment was perfect. The o2 sensor bung is very close to the where the wire comes out underneath the car, so we zip tied the extra wire to keep it up and out of the way.
The pipe that goes into the muffler was a bit ovaled out and wouldn't fit. Seems to have gotten damaged in shipping. A few wacks of a mallet returned it to round and it fit perfectly. They didn't have any tips available when I bought the exhaust so its just running a straight 3" pipe out of the muffler. I actually like this, I've already had 3 cops pull behind me, look real hard at the muffler tip, shrug their shoulders and move on.
The exhaust was VERY loud after installation, but after 300 miles it has quieted down to near stock levels for highway cruising, slightly louder than stock for city stop and go, and "Hello how ya doin" loud at WOT. Since the install NO ONE has tried to cut me off on the highway and people tend to move out of my way when I come up behind them with a bit of throttle
Haven't been to a dyno or tuned, I have more things to do first.
Here is what I have noticed. Spool up is rediculously smooth, if I didn't have a boost guage I almost wouldn't know if I was making boost or not. The car rev's so much better its not even funny, I did my first (and hopefully ever) bounce off the rev limiter today coming off an on-ramp because it rev'd up so quick and smooth I didn't realize how fast it went up... and yes the mph was excellerating accordingly
So overrall I'm a happy camper. I'll probably be getting the SS 02 housing sooner or later, which I probably should have done with the exhaust but oh well... and the LICP.
I'm not sure I care for the Autometer guage I got with the Warrtalon package. I've never been a fan and I've never met anyone who has had one work longer than a few months... at least not acurrately. I may give it a try anyway since I have it though.
But I'd definately recommend the buchcur exhaust w/hfc and magnaflow. Just remember that for the first couple of hundred miles its very loud but will quiet down significantly after awhile at idle and light/moderate loades.
