    well no real interest as ther is no XPIPE option. HMS is the way to go for sure with the vavle system. ABT noise is just a little louder than original. to do that better is to do nothing in my view

    normal means no flow exchange from left to right. XPIPE. means you make a connection right after the downpipes to equilibrate the counterpressures. always a good thing to do. I reckon I dont' understand why neither BMW neither AUDI does it on their V8 engines. all good exhsust manufactures do it.

    difference between std and sport AUDI exhaust are in middle and rear mufflers which their part number differ. whihc would mean they have opened up a little the sound.... frankly speking I've heard both and the difference is not worth it. far beter to take std and change with aftermarket.... It is different for a TTRS where the sport version is more differente that std. and I reckon a TTRS sport version is good as is in sound for exemple (I show you this example for you not to think I am pushing for a sale, but being objective about things)

    Supersprint does nor sell with valves. So this is either not a supersprint or a modified one off version! We spoke with the supersprint guys and tols us they would nor go with valves...

    this si very well made video marketing wise. but the sound of it and the functionality is beter and exists since over 2 years from HMS tuning. I am resellign these products and have sold a lot of these exhausts to RS5 owners.... it is the best exhaust around fro RS5s.... no doubt.....

    when closed its calm, when its open irs pure FERRARI V8 sound. its simply unblievable you are able to get that sound from this engine... I perosnlaly changed two tims exhsusts on my RS5 and once HMS was on, it was IT.... impossible the change or find better

    Glad you like it. The exhaust in your link is nice but baby if you compare it
    The inconel exhaust I posted has full de cat manifolds . The extra power and sound is amazing.

    Pic of the inconel manifolds


    Video made by the owner of the RS5. At the end hear the diffrence between valve on and off . Starting min 2.00

    hi youry,
    long time no talk, been busy with my car in Australia,
    I got the RS5 headers from felix and about to install them, also run non resonated down pipes with X-converter in the centre and KLine rear mufflers (the louder version),
    the sound is epic, dont get me wrong here the HMS is my second best, only got couple videos (youtube) so far cause it's still settling in ...
