They installed the bull x on my rs4 b9 and a Kufatec link to keep the valves open at lower revs. Altogether for less then €1500. Sounds really great and i see no need to buy a more expensive sport exhaust like the well-known brands. Great solution and the OEM sportexhaust stays mostly in place

You paid 1500 for the center pipes and the link or full exhaust and link?

do these fit with factory GPF?

[@zachao9259]

I just installed bull x but I noticed that the two round shaped pipes are catalytic converters not resonators?

[@MrIntercoolers]

Does that RS4 have factory sports exhaust?

[@JJ-bg1uf]

Excuse me, will it be uncomfortable on the highway?

[@thomasemmanuele9278]

No, it will not cause drone with an otherwise stock exhaust.

[@joglimanonfire7426]

Do these fit rs4 b9?

[@thomasemmanuele9278]

Yes they do.

[@Mathewmartialart]

funny thing , is that the original pipes sound far better. the x pipes sound meek

[@xXIMakeYouRageXx]

Is there a reason my rs5 isn’t as loud with the same installation?

[@MTB_FPV]

Gpf model?
