Custom Exhaust Options??

I am going to be purchasing a new Stella 4t shortly in the next month or two and am wondering what my options are for custom/aftermarket exhausts. I am basically looking for the loudest sound I can get without compromising performance, decreasing back pressure, or damaging the engine. I am not opposed to a cheap solution, but I am also willing to spend money on a different muffler if that's what it takes.
Sorry if this topic has already been covered...I tried searching and couldn't find anything related specifically to Stellas.

If you want a loud pipe that does absolutely nothing for performance i would suggest a Harley.

yeah.. you'll want to do something, as the 4t stock exhaust is prone to cracking and breaking off at the first bend out of the head...
i made my 2010 Stella louder... but it took some work.
dont know about performance pushes, but ti got somewhat louder.

Hmm, my loud pipes Dyno'd an additional 6hp.....so that is a rather silly statement.

A Stella 4T is rated at a BHP of 8.3. I find it hard to believe that a Stella 4T motor gained 73% more power as measured at the rear wheel. This would translate to about a 100% bhp increase by adding a pipe and no other modifications...patent your process...sell it and make a few million because nobody else has figured that out.
I've used expansion chambers on modified 2T motors...they are loud but when they hit the power band they kick the snot out of the power...especially with other carb, crank, and porting mods.
My point is that, in my opinion, loud pipes that are just to be loud are a waste of time and money. As stated by the OP all he is looking for is a noisemaker

I think SonnyD meant his Harley gained 6hp.
If it was the Stella, sign me up......

Well, that would have been a better statement then the Harley one...and I agree...

Cut the pipe open, core it out, weld it back together.

The Gianelli exhaust is a popular upgrade on the 4t's over here as well as fitting a ram air filter. Both of these mods make the scooter sound a lot meatier especially the air filter.
Also GPR make a quality looking pipe which sounds great too.

No sorry,I only discovered it myself a couple of weeks ago. It's not much more expensive than the Giannelli but looks much better quality.

I think Genuine has to decide to get the 200 emission certified for U.S. sale......They are riding the fence for some reason.
