What kind of baffling did you put inside the single chamber unit at the top?

The deal with boxster mufflers has always been annoying to downright deafening cabin resonance in the 2-3k rpm range. If you can produce a louder muffler than stock with no cabin resonance, I swear you will become a millionaire overnight if you don't charge people $1500 or more for it.

Oh yeah, you better dyno the car before and after installation with the same atmospheric conditions to ensure you don't lose HP or torque over any part of the bandwidth.

That setup will likely be too loud for most of us as those look to be essentially straight through. If you replaced those with Flowmasters that have chambers and baffeling then they may work for us, but the dreaded "drone" is the hardest thing to work out without testing. Jake Raby at Flat 6 Innovations was looking for some test mufflers so you may want to talk to him.

Light weight and loud as he**.

Many of the tracks have noise restrictions out here. At Laguna Seca we barely pass with stock pipes Yet Harleys with straight pipes go by me all the time on the freeway. No rhyme or reason to many of the laws here in the golden state.

these are straight through mufflers similar to our track mufflers and some of the custom stuff I do for our engine builder customers The price point is going to be in $500 range in brush finish. but I am not here to sell them just simply get the feedback you are all giving. thanks and keep it up. if you want to see some of my work go to www.mkexhaust.com again though not trying to sell anything yet but doing more research
