also on user told me to change the pulleys but i dont know why .. i already have pulleys on my car.. anyone know why?
A lighter under-drive pulley allows the car to rev up and down faster, giving you a bit better acceleration. Price/performance wise, they're pretty worthwhile.

i know what the pulley does .. I already have them on my car .. but someone told me to change the one i have ... i have evosports .. and one of the options was to get evospot one .. i dont know what was his point ..

Unless you're having a problem of some sort, it's probably not worthwhile. The difference between different aftermarket pullies is too small to make the $$ worthwhile.
thank you so much .. I love the kresissieng exhaust system.. but the power is important.. do you think the rd gonna sound better than the EVOsoprt exhaust system and headers.. I listen yo some of the clips of the rd full exhaust system and its not that good..
Why don't you get the RPI GT exhaust system....it gives you dyno proven power gains and sounds sweet at the same time. I didn't like the sound of the evosport headers because it makes my v10 sounds like a throaty v8 muscle car. But that's me, it all depends on personal preference. I would recommend you to get either RPI or ASR's complete exhaust system. I think those 2 vendors have the best exhaust system for our beast!

I Want the car to sound like F1 ( I think I can say high pitch)... Not Like american V8 car ...
Am looking for a good headers good sound ... Good power ...
With respect to the headers, pitch is mostly determined by the size of the primaries. Many aftermarket headers increase the size of the primaries, which lowers the pitch (as well as lowers the exhaust gas speed). Longer lengths also do tend to lower the pitch, though not as much as the diameter. Headers that are not equal length tend to change the actual characteristics of the sound, from the natural V10 sound to what some have described as more of an american V8 noise.
