<br>I've gotten quite a few inquiries asking questions about the 997.1 and 997.2 Dundon Race Exhausts.&nbsp; Through our work with the 991 GT3/RS in an effort to make a race exhaust more livable on the street and after much testing we found the stock muffler to be quite well suited to the task.&nbsp; It has low restriction to flow, allows the pressure waves to cross over from side to side (enhances torque) and is quiet when used in conjunction with valves!<br><br><br> <br><br><img src="http://cimg0.ibsrv.net/gimg/rennlist.com-vbulletin/640x480/80-img_1048_f214fdaa4b99df25a1016e03ec1af9cc34451494.jpg" title="" border="0"><br><br><br><br>Dundon exhausts are made from 321SS, this is superior and more expensive than 304 and yields a product we can offer a structural lifetime warranty on!<br><br>Lastly, our products make power, not sometimes, not on just our dyno, but all over the world in all conditions.<br><br>29.5whp gain at 6000 rpm, no difference with flaps open or closed for hp or torque.<br><br> <br><br>Makes a 3.6L same as a 3.8LRS up to 7300rpm<br><br> <br><br>From Rennlist Member John Chan<br>I am happy with the center exhaust option and there is no drone. I can
listen to radio like stock, what a surprise. Wife approved for a long
trip to track. <br>
Note: I have cup cable and stiffer tranny and engine mount bushing replaced.<br>
Also, the dyno is showing factory Ecu tune and I am sure more at the lower end can be extracted.
<br><br><br>To continue to serve the 997.1 GT3/RS (and the 997.2 GT3 as well), we designed a 4.0RS dual cone airbox that mates with the factory decklid.&nbsp; This is something that's been missing and we're happy to have it released<br><br><img src="https://cimg5.ibsrv.net/gimg/rennlist.com-vbulletin/1280x1280/80-img_5154_d1e275043cc6392c77374681e186065bc56f02e8.jpg" title="" border="0"><br><br>We're not done yet, we're still working to complete our 997.1 plenum upgrade.&nbsp; It's still in finishing being made, but we're excited to get it on the car and try it out! <br><br><img src="http://cimg0.ibsrv.net/gimg/rennlist.com-vbulletin/790x826/80-img_4439_305c8b6f6294672b89344cc4927b78f491f719ba.jpg" title="Dundon%20Stage%203%20Plenum%20" border="0"><br><br><p><i>Dundon Stage 3 Plenum </i></p><br><br>Contact us for any information on our products, or to order!<br>jamie@dundonmotorsports.com<br>dundonmotorsports.com<br><br>

Quick update on this, the Stage 3 plenum is here and John dropped off his car. We're busy finishing 991 GT3 Catted development and GT4 Race System manufacturing jigs. In a few weeks we'll have John's car on the dyno for Stage 3 plenum and full Cobb tune revision!
