Black widow exhaust benelli tnt 135

Benelli tnt 135 with a black widow header pipe to stock mufflers!

[DY.]

I've just put the Black Widow header pipe (De-Cat) on my TNT 125, with standard rear muffler. Turns out the rear muffler is for decoration only. It does absolutely no muffling. When putting the black widow header pipe on, it turns the exhaust into a completely straight-through pipe with no baffles at all. It's way too loud. I've put a pipe-werx EQDB insert in it and it has made no difference. It's just too loud.

Did you have to reset the ECU or tune it after? This is about the only performance mod I’d like to do.

How did you make the bike start when the kickstand is down?
