greddy is NOT low quality....

get the mugen twin loop...thats my exhaust, when all I had was that an a intake...I never lost to another si with my mods.

 

also...the shit is better than everything these people have named.

 

i dont like greddy cause they always boast so and so diameter but there is always one section that is small as shit, like with dsms they say 3" cat back but really its 2 1/4" section then 3". "chain is only as strong as its weakest link."
Personaly like the Apexi N1

 

For a Si, if it is a 99-00 I like the HyTech or SMS header if money is not an object.

The JDM 4-1 DC Sports header is nice for the budget racer.

And exhaust.....NO QUESTION custom son!!!!

Now for the new piece of shit Si's Ummmm void my above coments.

No pun intended to those poor soles with the New Si's

 

I agree it is better then all the exhausts that's been named.. But my Exhaust hasn't been named!! I recomend the HKS Hiper exhaust just like the apexi N1 but a little deeper noise. I love it and i have done the same thing as zappas, ive beaten all the cars like mine with the same mods as me, but the the mugen twin loop is nice to sounds good and i ave read thats is is over all good in performance
