Muffler/tlumik

Zdravim,proba

Sorry,I couldn't post at all. I'd like to get piece of advice from you about maluch exhaust system. Well,there are 3 types of muffler mounted on 126s. I can't add picteres yet. There is the old(stary) one and 2new(nowy) ones that seems similar but have got different pipes.
According you, what's the best? Are they interchangeable? What does it take?
A confront between racing muffler,what's you favourite beetween Tekla motorsport and Michael tuning?
Is someone legal to use on the road?
A short guide line,please.
Thanks a lot in advance.
Bye/pozdravim

old type is better in my opinion. It's exchangable with new type, you have to change only the mounings.
And smartly tuned stock old type muffler is way better than any Tekla or Michael (for road use ofcourse)
best regards
