Veneer calipers? Weird, mine are made of solid metal!

Be careful with custom exhaust work. I put a lot of time and effort into making something custom and then discovered that the length of pipe that makes up a Boxster exhaust forms a really loud resonance around 2800 RPM. Unless you add about three feet of pipe to each side of the exhaust (or make a chambered muffler that does the same thing) it's going to resonate like a mofo.

I have a really nice custom exhaust ... hanging in my buddy's garage because of this.



Not trying to discourage anyone, just trying to save y'all some money
