Straight to the point, which exhaust system is better in terms of performance? DMCH: http://www.delorean.com/exhaust.asp or DMUK: http://www.delorean.co.uk/DMUK/perfomance.html Looking at DMUK, the HP gains are minimal, as to be expected with a straight swap, with no engine modifications. However, I've never seen any dyno info from anyone who's switched out to Houston's system. I'm also draw to DMUK's design, as it appears to be relatively easy to swap out catalytic convertors when it comes time for smog inspection, and for the utilization of shorter pipes. I've read where some Esprits have had problems in the past with radiant heat from the Cats melting underbodies in idle traffic, because there was no cooling airflow. Even though Houston states that their cats are ceramic coated, is this still something that I should be concerned about since with Houston's set up, the Cats swing so far outwards to accomodate the larger headers? On the plus though, DMCH's system appears to use larger pipes to accomodate a larger volume of exhaust gasses (incase I swap out to another PRV with larger displacement). And just as importantly, does anyone have any sound clips of these systems? I know that the DMUK comes with different tones available, but I've never heard a single one. And the only recording I've ever heard of the DMCH setup is someone red-lineing the engine, to the point where it kills the gain on the recording device. Turning the motor over, reving it a bit, letting it idle (fast and regular if possible), and a final shut down would be great to hear. -Robert vin 6585 "X"
