what about the stillen exhaust? seems like it has near same gains as the FI and it sounds nice to, this is the one i am looking at getting.

Very happy with my Topspeed! Sounds awesome!

Question for those with the TopSpeed....do all the tips stick out way past the rear bumper??? I have seen pics where they sit pretty flush and some pics where they stick out a lot and it looks terrible. Please fill me in.

They are adjustable mine don't stick out much and I have the titanium.
