the "extra" tips are all but decorative only

guaranteed there's nothing those extra tips add but style

you'll get the same gains with a standard high performance exhaust

The Eisenmann Quad system is not for everybody however I like the fact that our customers have options when looking into buying an exhaust system.

hey, if you can sell it to people, and people buy it then more power to you!!

you can't possibly justify some other gain other than style by going to the 4 tips though can you???

not that style isn't important and worth $$$ to lots of people
