@ akonasadni : wat kind of car do u have
? it realy depends,... there's different kinds of headers,... if ur car is 4 cylinders,... there's a 4-2-1 header,... 4-1 header,.... and also depending on the outlet of the headers,...
changing just the exhaust manifold,..... i dont think ur gonna notice any difference in gas mileage,....
mufflerhaus
? where is dat at
and where u from
?
@ riko diko : the Simota is a basic performance SRI,..... it will perform like any other SRI out there,... u will get the HP gain and u will get better gas mileage,....
CAI give's u a more noticeable reation to ur car,.... compared to the SRI (like the one Ranch has install'd to his car)
from Rance's picture,.... his Simota SRI tube looks like its mandrel-bent,... and dats a good thing,... the only thing i would do to it is,... change the air filter to K&N or APEXi air filter,... WAY BETTER air flow,..... so u get alil' bit more HP,... n save bit more gas,...
