Performance loss changing backbox - H&S to TSL grp N?
I can't decide if I want to change my H&S angled exit box to a TSL grp N box.
I much prefer the angled look but can't cope with the noise anymore. Furthermore I'm running the car constantly with the bung in and coupled with running a atmos DV (soon to come off) its making the car jerky as hell and I'm sure the fueling is all to **** recently.
Will there be any performance loss changing to the TSL box? Don't suppose anyone has a sound clip of it on a classic.

Can't imagine there would be any power loss.
I am uploading some video files as we speak. They may help you decide, but then again, they may not......
Here you go :
YouTube - Subaru Rolling Road - 321BHP
YouTube - Subaru TSL Group N Exhaust
P.S At Goodwood it records 95dB with a H&S Resonated Centre. Without the Resonated Centre is was 97dB.
