Just wanting to convert my 2018 A4 1.4 tfsi from single exhaust to double like the S4. Aware I can buy the TDI rear diffuser to accommodate a 2nd muzzle.
BUT...
I was never a petrolhead and since buying my audi... I'm obsessed and got the bug.
Anyone able to advise how best to do this?
Put a branch in the system to have 2 exits, one on the left and one on the right? or have a full double system put in to increase power too...
Any help would be appreciated!
(Don't forget I don't know much and am learning so Johnny age 5 terminology appreciated! )
