2003 Boxster Exhaust Mod
 

Just wondering if anyone has tried a performance exhaust mod for a 2003 Boxster and if they have had any luck with it.

Yes, read this: http://986forum.com/forums/diy-project-guides/19770-diy-exhaust-mod-%96-gain-10-hp.html

+1 on this mod.
No cost (if you have the drill bit already) and none of the resonance mentioned with many of the aftermarket mufflers.

I tried the above mod but still too quiet. Switched to a custom setup with deleting the muffler and used 2 3" resonators. Too much drone 2200-2800. I found a couple "small" mufflers that'll fit and should have that installed this week. Hopefully the drone will go away.

The "Crios" mod plus Fabspeed secondary bypass pipes is the perfect combination for me. No drone, and the sound is fantastic.
