will upsizing my mid pipe and removing the center resonator do any good to my car after installing turbo?any pros and cons>thks

 

the more u let the turbo breathe, the less lag ull have. so yes it will help going bigger on exhaust

 

how about doing a side plant exoz?will it be better?and wat injectors should i use to upsize?thks

 

I found this little short video on how a turbocharger works...hope this helps a bit...

do superchargers benefit the same from big exhaust like Turbo? I know superchargers don't run off exhaust gas, so....but it's still forced induction...so I don't know,

btw, say if my test pipe is larger then the cat back, will that create problems?
