The smell of gas was, of course, apparent with the fully catless set-up. However, with the stock (catted) midpipe, it was only detectable upon start-up.
With every post I get more and more confused!
I had the AR downpipes and the madDad mids installed with the original gaskets and the sound was horrible, pretty much like a rusty old car between 1500 rpm and 5000 rpm... after 5000 rpm it sounded deeper and cool
Now I only have the madDad midpipes with the stock gaskets and it sounds very good over 3000 rpm but when I'm in any gear at very low rpm it makes a very anoying noise...
I think I'll give the DPs a chance again but with the AR gaskets....
*Just for you guys to know... I don't have emissions or noise issues here in my country so DP's are allowed unless you are in a residential area and start drifting or making unecessesar noise....
