aii2kaii Posted May 19, 2009 Report Share Posted May 19, 2009 hey guys gotta question.. recently i heard from a mate that putting a sports exhaust on the AE92 4A-FC engine, reduces the output power.. I'm wondering if this is true or not Quote Link to comment Share on other sites More sharing options...
KEI069 Posted May 19, 2009 Report Share Posted May 19, 2009 If the pipework on the sports exhaust was bigger than two inch diameter and the engine is otherwise standard then it is more than possible that your mate would lose power. Quote Link to comment Share on other sites More sharing options...
Hiro Protagonist Posted May 19, 2009 Report Share Posted May 19, 2009 A good, proper exhaust with extractors and high-flow mufflers/cats/resonators etc should not lose you power. An exhaust which is over-sized or still retains the inherent restrictions of the stock exhaust will most likely lose you some power. In short, do it right and you won't have any problems. I gained noticeable power from replacing the whole exhaust on my 7AFE. Quote Link to comment Share on other sites More sharing options...
