S5 B9 Coupe - Glacier White
Problem solved……but the majority will not like it. If so, please click “<” now!!
Bought 2 x stainless steel 3” single inlet RS style tips, and installed by Beaudesert Exhaust, very well respected and also manufacture 4x4 systems, shipping Aust. wide.
Work entailed cutting both aft of the diff, removing OEM mufflers/valves/pipework/tips complete, and installing all stainless, flanges/8”x 2.5” round mufflers/pipework & adapters to tips. BE used their laser which was downloaded into their CAD and fed into their computerised mandrel bender to create the correct angle and length. The 3 x internal ends were flanged so the system can be returned to stock. The tips were originally to be cerakoted satin black. However, as BE were unsure if the inlet side of the tips had to be trimmed away, and by how much, they painted the entire section in satin black, with a gold fleck finish. Mindful that there is still a settling in period for the new sections, whilst it was not cheap, considering the work, the finished product incl. not loud and no dash lights, so far I’m rapt.
We have a pergola area off the end of an open-ended carport. When I sit in my favourite chair, sipping on a long 'Bundy' rum, I am looking straight at the rear of the wagon.
Initially the intent was to simply siamese the piping out of the OEM mufflers, cut the back of the new tips, attaching the pipes to the widened inlet tip.
On closer inspection BE were extremely reluctant to cut anywhere near the muffler outlet pipe, but before the valving (rhs), as they were most concerned they may damage the valving. I concurred, thinking many $$'s if I had to replace it.
Staff noted that the OEM mufflers' gasflow was an 'X' style, in that gases entered, say, via the left-hand inlet & exited into the right hand outlet pipe.
I mentioned about the poor chromework on the tips. Staff said it was not uncommon as the work of the cat was to liquefy the gases, which exited out the tailpipe but often was caught in the tip ‘metal roll’. It was suggested Audi could have simply had a hole drilled through near the tip.
I believe this idea was mentioned earlier on the forum. Whilst on the hoist, the owner looked under the new Audi/Porsche style V6 with the turbo in the ‘V’, and commented that for more power he would recommend new downpipes, with no problem with the exhaust as is.
Trivia, well not really!!! On preparing the job, I was asked where the battery was, to connect 'zappers'. Hmmmmmmmm???.....'nfi'!!!!.
Apparently it is located under the space saver wheel at the back, with a thick cable to the engine bay, ending with a junction connection.
