Your wish is my command鈥

Recorded on iPhone on boot with wired earphones attached to bumper with chewing gum鈥o not the best quality..but you can get the gist




Holy crap! Sounds incredible. I assume valve open in the recordings?

Currently the original down and flex pipe as per factory fitted to the 4C Race Exhaust which the vehicle was delivered with.

I鈥檓 looking at various Down Pipe replacements (both Cat and De-Cat) and if/when any upgrade eventuates鈥鈥檒l definitely post some new clips to compare it with the OEM part.

@fas74c The OEM dp with the almost 90 degree bend is what tuners have pointed to me as the limiting factor. I really like the tri-tips, and wish Scara73 would sell them as part of his system.
