No noticeable noise difference.
These were real bolt on. you gain power and low down torque. For mapping I am not sure because I did crank pulley at the same time so I needed remap
On the PLM website there was a substantial discount available on these before Christmas, worth looking ASAP as it might be for the Christmas period only.

Simon from here had them for some time, I had discussed with him beforehand.
No complains so far. The only think they turn purple after a while, but this is normal for SS metal.
Still fine on my car, had them for several years now. Straight bolt on swap for standard. No real noise difference unlike long tubes, but I didn't want my car to be too loud anyway. My car compared to similar modded cars without shorty headers had good torque and power gains.
