Hello i just installed my aftermarket exhaust system and here is the result...

 

 

 

Im not thet happy about it because now i get this annoying humming sound when hold 110 kmh steady speed.

But it was cheap 145 Euro. (162 dollar)

 

Have you any experience with aftermarket system?

Aftermarket exhaust is generally garbage unless you spend as much or more than factory parts cost.

"Aftermarket exhaust" is all but meaningless - we can't comment on it as they vary wildly in fit and longevity depending how it was made.

 

That's like asking if a restaurant is good - depends what restaurant and what you're looking for.

 

It also depends why you're replacing them - P0420, rust, poor diagnosis, performance, a mixture of those.

 

I've had aftermarket rust in a year or two. Other aftermarket lasts longer but few will last as long as OEM in terms of rust or P0420.

I see i could choose this cheap or Feritta stainless steel.

Oem is way to expensive.

I replaced my exhaust because of rust and welds start to crack up.

After dismounted the two last muffler i noticet there was about 2 liters of water in them.
