Please bare with me.
I rather fancy a Quad pipe setup on my 3.0 TDI, S-line, B8.5.
The current twin pipe job exits through a silver gray plastic moulding with a black honeycomb insert that appears to be seperate part from the bumper? I assume both this sliver grey & black part to be the diffuser?
Am I to assume that I can get another diffuser from Audi that fits my bumper to suit a quad pipe exhaust? would it be an S4 item?
If this is correct? does it come already painted grey & black?
Does the whole bumper need removing to change a diffuser?
Also with reg, to the Milltek exhaust, what is the difference with resonated and non-resonated system.? is it how loud it is?
I spend time on motorways so I dont want extra noise at cruising speeds, but it could sound better when putting your food down, not mention the Quad pipes look better.
Sorry for all the questions
