What muffler do you use with them? It looks like you have a short extension between header and muffler as do I.
I use short (10in) SuperTrapps. I could use longer ones without the extensions but I like 911 sport mufflers... they sound fantastic and need the extensions.
But I've never made one with the proper pipe size for the 3.6 engine... whatever that would be. Maybe the stock old sport muffler would be fine, but I don't have a muffler to convert any more so it doesn't really matter! SuperTrapps it is.
The short ones allowed you to run megaphones. One thing you can also do with the extensions is to weld a cross-pipe to soften the exhaust note and dampen the harshness under deceleration.
