Any Aftermarket full exhaust systems for ST3's out there? - Ducati.ms

Hi, does anyone know of manufacturers that make a full replacement exhaust system for the late model ST3's 2004-2006?

I'm definately interesting in going with a 45mm header and mid-pipe, and if possible an equal length system. I have not seen any aftermarket systems available. I wonder if something like a low-mount for a 1000DS motor would fit?

If you want to see some nice custom systems take a look at:

Ducat23,
I have emailed Staintune and offered my 2006 ST3 as the guinea pig for design and construction of a full 45mm system in 304SS. I am awaiting their response.
Cheers,
Deebee

Why would you want a larger diameter, full system in the absence of significant engine modifications? The result could quite possibly be degraded overall performance. Without assurances from an engine tuner that performance can be increased... seems like a big waste of money to me.

Don't know if everyone has seen the latest tuning from moto one on the ST3. Looks like bigger exhaust is wasted unless you can get bigger valves on the thing somehow.

Isn't 45mm the stock size? It is for my St4. And agreed with the above posts. Increasing dia will degrade performance short of head modifications.

The ST3 comes with a small 40mm headpipe, which is not an equal length design, and uses a "cludgy" cross-over arrangement.

While Brad does suggest this motor is undervalved, he also suggests that the 40mm head pipes are small for a 992cc motor.

Who's ruling out engine mods?

Perhaps we'll see some full systems available soon now that the 3V motor is the only one available for the ST's.

Coming from a BMW this bike still has more power than I'm used to. No big engine mods in my future. If I needed more HP I would have just bought a ST4s. I would like new pipes for a throatier sound. I'd prefer oval cans with Ti or CF tubes. I think polished SS wouldn't look good. But, I want to retain the easy to change high/low positions I have with my pannier mounts.

Very positive press from this board regarding Sil's. In fact I have a titanium set of slip-ons on my ST3 with open airbox and I think the bike sounds plenty nasty as configured. But that's just my humble opinion...

same here, C/F Sil Ovals, open air box and PCIII. Sounds great and the 4S engine is now a happy camper.
