veloci1 Posted October 26, 2007 Report Share Posted October 26, 2007 Can anyone that has installed either catback attest to whether or not there was a loss of backpressure after the installation? also, is there a drone inside at cruising speeds? who sells it the cheapest? let me know. i would like to get this mod done this coming week.

veloci1 Posted October 27, 2007 Author Report Share Posted October 27, 2007 Would you consider a drone to also be a Whine ? Whine? no, i meant drone, defening sound at crusing speeds. i get plenty of whine fron the suprecharger on my lightning. Quote Link to comment Share on other sites More sharing options...

Last time I checked a loss of backpreasuer would be a good thing, but I've never tweaked a normally aspriated vehicle. AFAIK an engine is an air pump and you want to pump as much air as you can. Back pressure, IMHO, not good. Quote Link to comment Share on other sites More sharing options...

AFAIK an engine is an air pump and you want to pump as much air as you can. Back pressure, IMHO, not good. there is a delicate balance that must be kept between back pressure and performance. if you have too muck flow (lack of back pressure) you will lose torque and performance in a hurry. if you do not have enough back pressure, then, you choke the air folw and the performance of the vehicle. i have done many things to my Roush II and Lightning and i have learned that back pressure is one of the many importamt key whenever trying to gain HP. i am assuming the Gibson and Magnaflow did their homework, but, i assumed that on a catback i installed on my mustang and regreated it. i was able to get the manufacturer to admit that the piping for that application was too big and the exchanged it. this is why i would like to hear first hand experiences on any of the catback available. i doubt that i or any one will see more than 10 hp gains. but the sound is worth the install if and only if, there is no loss of backpressure.
