BandB has created the only 3″ quad cab extension pipes on the market. Don’t create backpressure and loose power by using the stock 2 _” extension pipes with your 3″ midpipes. Install these for a true 3″ exhaust system! Quad cabs have an extension pipe assembly between the midpipes and the catback to bridge the gap due to the longer frame. Until now, new extensions had to be fabricated at an exhaust shop and rarely would they be made out of stainless tubing or to such a high quality as these. BandB noticed this need and created these 3″ diameter extension pipes just for quad cab SRT-10 Ram owners in mind so a complete 3″ exhaust could be a bolt-on feature. NOTE : Slip fit ends can be combined with other 3″ catback exhaust systems also with slight modification.
