TME sportexhausts are designed and manufactured in Sweden, by TME since 1977. A TME sportexhaust delivers everything you demand of a performance exhaust system in looks and quality, without making a noise about it. We only use stainless steel alloys, mainly 304L (EN 1.4307) suitable for exhaust systems in production. Larger diameter means increased torque and horsepower in the mid and upper rpm range. Especially on turbocharged cars, where boost will come in at lower rpm and with improved throttle response. With a TME cat-back exhaust, the backpressure and temperature measured before the catalytic converter are reduced from 30 to 50% and temperature with approx. 10% on full load compared to the original exhaust. That's why a TME sportexhaust is required with all engine tuning packages. (See test graph below. Click to open it in full size.)

TME silencers work by absorption. The sound absorbing material used is stainless steel wool and special, long fibre glass- or basalt wool. There are no power robbing baffles, so back pressure is minimized. All exhaust systems conform to European noise levels, and have a pleasant deep note. The car can be driven all day without drumming or audible discomfort. All TME sportexhausts are fitted to the standard mounts without modifications. All necessary installation hardware is included. Tailpipes are not sold separately.
THERE IS NO E-NUMBER ON THE CATALYST
A stainless steel downpipe with a racing type catalytic converter with platinum coated stainless steel monolith as a complete unit. The 120 cell catalyst made to TME specifications, that can keep the emissions within the limits. A 200 cell catalyst is optional for some of the older downpipes, which can reduce the backpressure about half way compared to the 120 cell. OEM quality 3-layer flex coupling. Can in combination with a TME sportexhaust reduce exhaust back pressure measured before the catalyst with up to 85% compared to the factory system. A downpipe will make the car louder, more on direct fuel injection engines (3.0 SI 6-cylinder and VEA 4-cylinder) Image below show the cell density and difference between 100 and 200 cell catalysts.
The TME turbo downpipe is required for stage 2 and higher levels of tuning. Power increase depending on application but will make a noticeable difference on throttle response under acceleration and therefore will reduce the 0-100 km/h times in some cases up to 0.6 seconds. A perfect product for high speed Autobahn driving where ceramic catalysts are subject to meltdown and frequent replacements. Will slightly increase noise level inside the car. For most models, a different tuning software is required. On 850, S70, V70, C70 first generation, the use of a downpipe may shorten the life of the exhaust system, if a larger than stock turbocharger is also used, combined with very unique high speed driving conditions.
Note! Exhausts and downpipes are made to order and usually have a few days delivery time or more, depending on material stock. We do not make one-off exhausts, unless it's a minor change we can do with existing material. Minimum order quantity for a new exhaust system or downpipe is 25 units.
