RS5 exhaust modification?

[SpeedShot]

I don't ride in winter. Probably i'll start at April or March. I wait for May and after that i'll contact you

with pleasure. hms exhsust takes about 3-4 weeks to have availabkle (on make to order basis)

Have anybody tested ABT Exhaust?

[youry]

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

Hi,

What is differences between normal and x-pipe?

Do you know differences between audi original exhaust and audi sport exhaust system for RS5??

Thx

[youry]

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)

Ok, and when i change it for HMS original remote valve system is stayed? I mean now when i switch the mode for Dymanic valves open, but when i"ll have the hms will it be same??

[youry]

yes it will work as original valve control indeed.

[SpeedShot]

And what about fuel consumption?

[youry]

no impact (i did not see any on my RS5)

Hi,

do you know something about this? Same with X-pipe: http://shop.revotechnik.com/products...s5-42i-v8.aspx

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...
