Hi guys, and thanks for the feedback
I have narrowed down the search a bit. Both Brabus and Kleemann used to produce model specific mufflers for the 32 AMG but these were discontinued a few years back - due to the scarcity of the car, they were made to order only, so I doubt there are any of those hanging about waiting for me to buy them (but who knows).
On the other hand, I have managed to pin down a couple of mufflers (section 3 only) specific to the 32 AMG made by Eisenmann and Vaeth.
- Eisenmann have two tip variants, 2xRound or 2xOval, the latter being preferable due to it being visually almost identical to the original AMGs, and two sound variants, Sport and Race - the Race being like having the devil himself jammed into the muffler.
SLK 32 AMG (260 kW)
Artikel/Endrohr -- Durchmesser -- Bestellnr. -- Preis
-- 2x ø 83mm -- D7233.00831 -- 833,00 €
-- 2x 90x70mm -- D7233.02240 -- 856,80 €
I don't know what your view is, but I think the price is very competitive for a state-of-the-art product (I have been told Eisenmann is the best of the best in craftmanship and quality). It's a relatively cheap mod, the Eisenmann's on the 350 R171 for example cost twice as much at Eur1,500.
- Vaeth has also got model specific mufflers for the 32 AMG, with an 2xOval option for sure, but their service guy is to come back to me with more options - no idea on prices here.
The advantage of the Vaeth is that apparently these can be clamped vs. welded (which is inevitable in the case of the Eisenmann), which gives me flexibility to go back to the original AMGs if I need to. We have to go through a TüV-like inspection every 2 years in Spain and if the sound/emissions are too loud, I may have to put back the original (just for the exam!!). The homologation process is a nightmare in Spain as the laws and procedures are still those of Franco's time and have not yet adapted to the real marketplace - even bribery could still be used to 'ease' the inspection process if necessary (yes, in the European Union in 2009!).
By the way, does a change in noise levels necessarily involve higher emissions?(never cleared that up in my mind).
My primary goal is to keep the car for years to come and the secondary (or terciary) matter is not just to improve the sound, which is quite good especially in high revs, but to get it where I want it to be (deeper, fuller, rounder). That's why I am only opting for a change in muffler (section 3) but I will certainly stop moving forward if this will adversely affect the engineering of the system (would this really be the case with just a muffler change?).
On the other matter, I have been reading about other mods such as those kindly mentioned by you, Alroumi. However, and following on from the latter paragraph, my car is 100% original and I would like to keep it as much as possible in that way, especially since I am actually more than happy with the car's current response - it is already very quick. The sound is really an aesthetic issue, it's the icing on the cake for me, but as you can see I am putting a lot of thought even on a 'simple' muffler change - damn it, it's like being virgin again!
However, more than happy to consider other mods if these don't affect the long-term durability of the engineering (or if they actually help improve such durability).
Anyway, I think the key here is to find 'my other half'...a brave man, a pioneer, someone who has gone out in the dark all on his own and gone through all the 'dirty work' I am going through now... that is a man who owns an SLK 32 AMG and has modified his mufflers...where are youuuuuuu!?
Very many thanks for the info chaps and sorry about the long novel here. Any other feedback/thoughts would be very welcome. I trust you guys, keep up the good work!!
ps. the absolute best would be something like the On/Off systems that I've seen in buddies' Maserati GranTurismo and Porsche 911. Factory installed, with the on/off switch in the cabin, ideal for long trips and to avoid upsetting neighbours, law enforcement officials et al.
