Looking to get a new exhaust system for my B8 S4 avant and was wondering what i should go for any advice would be appreciated.
As I have mentioned if you type drone into the search of the B8 forum you will see the issues first hand. As far as I am aware and others correct me if I'm wrong the only guaranteed drone free exhaust is the new Scorpion one labelled drone free. But if my trial and error is anything to go by it will not be much louder than standard. I ended up basically replacing all the factory boxes again albeit in stainless to get rid of the horrendous drone. As mentioned above power gains are minimal, if its for looks just change the trims, if its for sound try swapping the centre box with an x pipe first. If you like move of not cheap to return to factory. I started off thinking I was being clever having one made so it would be cheaper and ended up with a lot of scrap stainless in my garage and double the bill I expected. I do still have two stainless straight through boxes and a stainless x pipe in 2.5" if you want to try your luck at your own system.
I did read your OP buy forget, did you ever fit just the X pipe, with the rest of the system stock?I actually have two X pipes. One is a Magna flow bought through fleebay. I didn't like the quality so bought another through longlife exhausts. Its a 304 grade stainless 2.5 inch. If its trial and error as to what you like I would start with the Magna flow it cheap on the afore mentioned site. If you like it after a few days you can always upgrade if you wish.
I have been pondering switching my tips to black but Audi wanted 100 notes a pair! Maybe go custom for 2 X black oval as I'm sure could do that for same sort of price.
Unless anyone used non OEM black tips??
