So I have a 07 Ms6. Mods thus far are Cpe standback tuned to 18 psi )11.8 AFR. 3" custome exhaust. Ets TMIC. Mazdaspeed Cai and hks Bov. I haven't dynod it yet it was just street tuned I orderd a cpe catted downpipe should be here for friday what can I expect from the downpipe. I will have basicly every mod you can do to this car (excet upgraded turbo) just curiouse if I will REALLY feel the downpipe along with all these mods and were will I feel it the most. Iam very excited and happy that this will be the end for me and modding. There is nothing else to really do..lol. I have springs and sway bars Btw for suspension mods and motor mount which I forgot to mention.
Thanks guys..
