Hyundai Genesis Coupe 2.0T Pictures and Dyno TSUDO SE Cat-Back and Downpipe
Posted by Andy in Dyno Tests, New Products, Speed-Element Motorsports, Test Fits / Prototypes, Tsudo Performance on July 19th, 2010
Dyno results are in for Speed-Element’s Hyundai Genesis 2.0T Cat-back and Down-Pipe exhaust system.
This exhaust features 3″ / 76mm outer diameter into dual 2.5″ pipes. 3″ front flange bolts to the stock O2 housing, allowing for a future upgrade to a 3″ O2 housing without cutting or welding. Piping splits into dual 2.5″ pipes with dual canisters to keep the exhaust mellow and smooth while still having straight through performance. Downpipe also features a large resonator to prevent noise and rasp. The exhaust is finished off with quad exhaust tips, which are double walled, stainless steel, and slash angled for a subtle but aggressive look. The whole combination allows for straight through performance while keep the car street friendly without attracting unwanted attention from the police.
Tested on a Dynojet dyno at SR Motorcars. Our test vehicle had an Injen intake and blow off valve. No boost controller, exhaust, or any other modifications. Stock ECU was used on the vehicle with no tuning before or after. ONLY the down-pipe and cat-back were swapped for the dyno comparison.
The exhaust showed solid gains in the mid range all the way up to redline. The torque spiked during the run with the stock exhaust which caused it to show higher numbers than the Tsudo exhaust. Once power stabilized the Tsudo exhaust shows a consistent gain in torque. More power can be easily had with tuning to smooth out the power and take advantage of the increased exhaust flow.
+18.45whp / +14.59wtq @ 6500rpm with just a bolt-on exhaust swap

New Tsudo Chevrolet Cobalt SS Supercharged Cat-Back Exhaust System
Posted by Andy in New Products, Speed-Element Motorsports, Test Fits / Prototypes, Tsudo Performance on July 1st, 2010
Our brand new Chevy Cobalt SS exhaust system has arrived! System uses 2.5″ OD piping specifically for the SS supercharged application. Straight through resonator, N1 muffler, and full mandrel bent piping for maximum exhaust flow. N1 style muffler with a 4.5″ muffler tip for flush fitment with the OEM rear bumper cutout.
Perfect complement with other bolt-on mods. Use this in combination with your intake, header, and downpipe! Installing an oversized 3″ exhaust on an SS supercharged engine will only cause a decrease in low end power on most applications!
In stock and ready to ship, get yours today! Check out the Cobalt SS catback page for more details.
