I heard exhaust systems on 08 si sedans are hard to find...

 

It depends what ur looking for i know Greddy and Skunk2 have been in and out of backorder for all of them. Plus since you have a sedan you'll have to either extend a coupe's exhaust get the Greddy extender or get the sedan version of the exhaust you want(which Greddy isnt coming out with). So what do you have in mind? In the FAQ there is a list of them https://honda-tech.com/zerothread/1943086

 

i was in youtube the other day and the skunk2 sounds nice but i was just thinking of gettin a short ram intake first then waiting on a sedan version of a good exhaust

 

since my car is fiji blue pearl i was looking at carbon fiber hood and hid lights for it then working the engine out..my friends tell me to just put intake,headers.and exhaust and a lighter flywheel but am not sure of the flywheel...

 

I have the 70mm skunk2 and i love it its a bit loud for some but i love it.

Misconstrued: Most places have the sedans in production its that they are harder to find its almost easier to just get a coupe one and extend it.

 

injen makes pretty good intakes and sound good too i have one on my 2003

 

anyone know if a short ram or a cold air intake makes more power? i know it wouldn't be much, just always wondered.

 

You could find the answers to all of these questions by searching but nonetheless, a CAI works better by sucking cold air from near the bumper or somewhere lower in the engine bay. The short ram usually sucks air in from where the stock filter sat originally just without the restrictions of a stock intake filter and pipe.

 

dude would it be a risk getting parts for my new si and loosing the warranty or how does that work???

 

I also have a sedan and i picked up a Greddy Evo 2 exhaust from a friend of mine and just had it extended 2 inches in the middle. Sounds good with injen intake and RT hi flo cat. Good choice on color too, this may be the last year for it.

 

it should just void part of your waranty like the stuff you moddified
