QUOTE(clawhammer @ Apr 30 2012, 08:53 PM) Anything you change on the front of the exhaust system will give you substantial difference (compared to anything on the rear for a start)  As to whether it gives positive/negative difference, it would depends on the design. Please remember that car manufacturers have proper equipments to test and do calculations to come up with an optimized exhaust design. Those kedai Ah Beng exhaust shops have nothing but mufflers/piping hanging all over which claims they can do wonders. If you can find proper design/tuned exhaust for your engine, it would be your best bet. However it would cost you a bit more  so in other words are you saying that superstreet extractor is good / reliable? cos since I'll be using quite some amount there I really hope not to make a mistake. |

I see, other stuffs also, that is for sure Because there is no way you can get 145whp with just cams and open pod + exhaust mods This post has been edited by shinjite: May 6 2012, 11:09 PM |
