Quick update
I received the exhaust in three parts :
Header & Overpipe
Midpipe
Rear silencer
I decided to wrap the header with DEI Titanium wrap to avoid heating the engine oil and bay too much.
That was for the start of the week. This week end I decided to install the full exhaust in my tiny garage with my car jack stands, it took me the whole day which is pretty good knowing my exhaust is old and has 90 000km (~60 000 miles).
I also installed a sound generator suppressor part I 3D printed
It was dark by the time I could go out and try it out but I spent 40 minutes smiling. The sound level is a bit lower than with the original exhaust when cruising and that's without the sound generator. I didn't find any drone or noise I didn't want to create .
Once you start putting some load on the engine, the sound becomes great ! It revs with a sound I could qualify of stainless steel sound. The exhaust really answers to engine load, if you rev slowly it won't be very loud, if you give the accelerator a dab, it will become more "dramatic".
I really love this exhaust and I think it's what this car was lacking : sound and no torque dip (soon for me with my remap). If someone is interested I'll post some pictures / videos of the car with its new exhaust.
