Sagawara 1.3 minor modification

[bopp_086]

Greetings everyone...
i'm currently driving a '03 manual Iswara sedan.My engine setup is like this:
4-2-1 extractor with stock piping,infinity swirl centre bullet and Pro1 muffler
open air filter with aftermarket intake pipe with cyclone device
HKS voltage stabilizer with 6-point grounding wire

if anyone can suggest to me anymore minor modification can be done to increase the engine response??is changing the piping to 2" size is good??or sumthing wrong with my setup??

feel free to comment here,any opinions will be highly regarded

bro,1 3/4" inch piping is suitable for ur car.....if u use 2" piping,it will drop down ur performance...change ur spark plug and cable too...it will give u better response....check ur center bullet,r there in correct place? and the piping after center bullet.....

use 2 inch piping for 1.3 will drop performance?
