rcz0ntn Posted February 19, 2009 Report Share Posted February 19, 2009 I am looking to upgrade exhaust for my B6 S4 Cabrio and will buy Milltek as Audi dealer sale and installation is available. I plan to install in two stages. First is the catbacks (this month) and then the downpipe next year. Does anyone know if the non-resonated catbacks are overbearingly loud with the stock downpipe? What about after I purchase the Milltek downpipe? I do not want to spend my money for a non-beefy upgrade that I am afraid the resonated will be, but also don't want the neighbors to hear me three blocks away.:confused: Link to comment Share on other sites More sharing options...

rcz0ntn Posted February 20, 2009 Author Report Share Posted February 20, 2009 I don't want to buy them but did you have experience with them. I'm interested to know what people think. Link to comment Share on other sites More sharing options...
Scotty Posted February 20, 2009 Report Share Posted February 20, 2009 I have the resonated full system. It makes a really nice noise when being pushed and it's subtle enough at low revs that you don't annoy anyone. Any louder (i.e. non-res) and I think it would bug me on motorways etc Link to comment Share on other sites More sharing options...
rcz0ntn Posted February 22, 2009 Author Report Share Posted February 22, 2009 I appeciate the information. Why are you selling your system. Is there anything that made you unhappy with your purchase? I have all work performed by my dealer and they offer Milltek, so other than that I'd take you up on your offer to purchase yours. Link to comment Share on other sites More sharing options...
Scotty Posted February 22, 2009 Report Share Posted February 22, 2009 I've had it on the car for 5 years and if you look at my posts you'll see I LOVE the sound etc. It's only being sold as I'm changing cars soon and I won't get any thing extra for it in part-ex so I'm spreading my joy!

johnp68 Posted February 22, 2009 Report Share Posted February 22, 2009 Another vote for resonated here. Sounds great when you put your foot down, without the full on Max Power effect! Not sure I'd go for the Miltek downpipes again though - nothing wrong with them, just not sure they make much difference, bearing in mind the extra cost Link to comment Share on other sites More sharing options...
Scotty Posted February 22, 2009 Report Share Posted February 22, 2009 I'd definately have the full system in preferance to a remap. Together they're fine but I'm not remap without. Did you get the sport cats as well? I found the full system works excellantly. Are you just talking about from a noise point of view? If so then the downpipes etc add to the sound but the main difference is definately the rear section. Was yours also a B6 S4? Link to comment Share on other sites More sharing options...
johnp68 Posted February 22, 2009 Report Share Posted February 22, 2009 I've got the hi flow sports cats , plus cat backs and Revo remap. The sports cats didn't make any noticable difference to the (perceived) performance, which was a bit disappointing. That's why I wouldn't bother again. Mine's a B6 S4 Link to comment Share on other sites More sharing options...
Scotty Posted February 22, 2009 Report Share Posted February 22, 2009 It's the perception thing that I found wierd with my S4. Coz the power is so continous and smooth, it's really hard for the "butt dyno" to get a true feel. I wasn't sure the car was really performing .... until I went side by side with another car I knew the performance of. Link to comment Share on other sites More sharing options...

That's why people who normally drive a turbo car like a Scooby or an Evo think that an S4 or RS4 are slow, they are so used to the "kick" as turbo boost arrives that the continuous linear power delivery of our cars makes them think they are slow. Shows how easily our senses are fooled... Link to comment Share on other sites More sharing options...
Scotty Posted February 23, 2009 Report Share Posted February 23, 2009 Exactly. Human bodies can only detect changes in acceleration and not actual acceleration. Link to comment Share on other sites More sharing options...
rcz0ntn Posted February 23, 2009 Author Report Share Posted February 23, 2009 Thanks everyone. I plan to go with the resonated. This input is helpful. I'd love to go with the chip mods also but am worried I might void my extended warranty. Seems I am limited to suspension and exhaust as warranty folks even frown on air intake mods.

spikeyboy Posted March 18, 2009 Report Share Posted March 18, 2009 I had the same question as you regarding what to get for the milteks. Ended up with the res cat back, plus sports cats and AMD remap. Sounded very loud at first but it soon beds down and the noise quittens down - as scotty said any loader and it would annoy on the motorway. now the sound is to die for. deffo noticed a huge difference in performace going from stok to full millteks and remapp - may be due to the different remap i have but i now get a surge of torch around 2,500 - 3,000 rpm - alost feels like a turbo cutting in. Oh did i mention the sound is to die for I do get rattle on my S4 - not sure what cuases it though as it stops after the egine has warmed up - dont believe its the tenshiners as the sound isnt in the actual engine - just sounds like something is lose like a cover.
