I'm not sure how much power can be gained with an aftermarket exhaust on this car.

The best way to do it is before install and after install on the same day to eliminate environemntal variables.
Did you do a before and after for the intake already?
When we did the exhaust on my last car, we changed the exhaust out while it was still on the dyno. After it cooled of course.

Had a JoeZ intake,F-Sport A/F and a Tanabe axle back exhaust on a IS350 that added maybe 12 HP.Not much HP but the IS did sound nice.

12 WHp gain isn't bad for normally aspirated (NA) engine mods these days. How much did it cost to get it?

About $200 for the JoeZ pipe and F-Sport a/f and $700 for the Tanabe exhaust.

Wow, the joe z sounds great, can't really hear the ISS, and the meisterchaft doesn't fit a GS at all to me.
