Last time I checked a larger diameter pipe is less restrictive then a smaller one; less restriction on a turbo car = more power.

Ti does not flex very well it will crack if push to the limit of tensile strength were as steel will bend. TI is very strong for it weight and thickness compared to other metals.

Steel is strong, so it will dent or flex

But I could be very wrong

As far as exhaust, the Buschur 3" with Magnaflow is almost as quiet as stock and performs very well.

I have the megan racing catback (along with helix dp and test pipe), and I have to say it works very well. I dont see how you could get a straighter, better flowing exhaust without mounting it in the middle of the bumper...heh. That being said, it is very loud since it does not include a resonator, and the muffler doesnt look like it does much. But it makes great power, which is most of the point.

With a very large >3 inch exhaust you will lose back pressure which will cause a lose in power with bolt on's. I have the hks dp and exhaust, I total recommend it for those that want great power and good sound (not to loud). I remember looking at exhaust threads like 2 years ago. This thread brings me back to the drive home from the shop with the new exhaust. Loved it.
