Dose a full cat back like the stillen make much of a difference over say a custom y pipe like we see in the recent posts or the fujitsubo. As i am most likely staying NA what is the best bang for the buck thats actually been tested so far for NA:
Crawford plenum
RT Cats
Y-Pipe
cams...
post some actual reviews!

 

I would say exhaust, one that comes with the Y pipe like stillen or greddy or injen. they will add about 9hp or so in the real world.

 

but i have "heard" that our exhaust is good and just to get the Y and Cats. also maybe first i was thinking of geting a plenum cause that seemed like a major problem with the Z, more so than venting exhaust? any actual experience anyone?

 

If you like the look of the stock muffler I would just get a y-pipe and a straight pipe and you get the same or similar gains as a true dual. My opinion is that if you stay NA you are probably better off with a y-pipe than a dual.

Many make y-pipes but I have only seen one mid or straight pipe and that is Japtrix which also makes the y-pipe which I have.

They found that changing the muffler didn't make any changes to HP.

 

just curious, but does anyone know why the Top Secret y-pipe is double the fujitsubo when it looks half a nice of quality? is it name or performance?

 

TITANIUM vs STEEL

 

aaaahhhhhh!!!!
