APR T304 Stainless Midpipe Exhaust System - Audi SQ5 / SQ5 Sportback (B9) 2018-2025

APR's midpipe exhaust system swaps the mid section of the B9 SQ5 exhaust for mandrel-bent T304 stainless steel, TIG welded throughout and left in a brushed finish. Flow runs through dual 2.5 in to 2.75 in downpipes into 2.75 in midpipes, worth 5 AWHP and 6 AWFT-LBS on its own and 10 AWHP and 12 AWFT-LBS when combined with the APR Rear Catback Exhaust System. Premium flex sections with a smooth interlocking liner absorb engine movement, while precision brackets and slip and reducer clamps line the system up against either the factory rear exhaust or the APR catback. Expect a deeper, more aggressive growl at wide open throttle with full emissions compliance.
