smiddy 76 Report post Posted May 21, 2009 Had my exhaust flow increased by removing restrictive section post cats. Modded useing 2 x 57mm tubes then into a 76mm merge collector. Was fiddly job with sensor ports and removing exhaust from headers to weld. Exhaust note is deeper but not louder. Not the neatest of welding but good design in a very tight space. More power for sure after 4000 to red line, car was flat after 5000 before. Quote Share this post Link to post Share on other sites

*Glenn* 854 Report post Posted June 25, 2009 (edited) I'm just wondering Wayne. Would you not have achieved more by going dual front to rear or are you going to try that later ?. Mine seems better going dual after having the 3" single BTW: I must ring Gavin and sort out a remap too Edited June 25, 2009 by *Glenn* Quote Share this post Link to post Share on other sites
smiddy 76 Report post Posted June 26, 2009 I hear you Glenn, this would classify as the poor mans catback. Ha. The cost of testing for a street car outways the potential gains. The section added is a vast flow improvement mod, at a modest cost. Will visit soon. Wayne. Quote Share this post Link to post Share on other sites
