Here is an example of our 991TT 3.0 muffler delete X-Pipe to be used with OEM cats and OEM tips. This one was just fabricated and shipped this week. It features 100% T304 Stainless steel construction, full tig welding and is completely made in the USA.

Our "X-Pipe only" version retains OEM emissions compliance, as it uses the OEM cats. All SpeedTech 991TT exhaust products utilize our modular design, so an upgrade to SpeedTech HJS cats or cat bypass pipes can be introduced at any time in the future. Even an upgrade to full 3" dual tips is an option.

6Speed Member discounts are available on all SpeedTech systems.

Here is a 3.0 catless "RACE" system with our custom 3" Dual Tips (full 3" catless system) on a 997.2TT. Pretty much the exact same sound on the 991TT - same motor, etc., this is the sound you could expect with the installation of our 991TT full 3.0 catless race system with our dual 3" tips.

RMDZidane is infamous around these parts
That's a nice exhaust note...despite the 90's era rap video editing
And of course the catless exhausts I'm most intrigued by, Speedtech and Protomotive are impossible to find videos of for 991 Turbos, even 997.2s

10ft long flames are the usual.. but not because of the exhaust whixh of course helps, it's the methanol injection


On a 991 I'm sure it crackles and pops like crazy
