I am afraid that may be a cheap import with who knows what for sound packing that has a danger of sounding like a coffee can. It will also be difficult because it will need professional installation. Bolt on is the way to go!
I had the mazdaspeed axleback on my P5 but it was too loud and not "wife approved" with my header. Very good exhaust though. People say they sound fine without the header.
If you want to go with the mazdaspeed I have them avaliable along with magnaflow mufflers and catbacks PM me for details!(thumb)
