im going to get my piping soon and im wondering what would be best with my setup.. i have a jdm b16 with blox intake manifold itr headers and running open from the cat right now. it pulls harder than when i had my 2 1/4 piping but now im planning on getting 2.5 or 3" all the way back with a stock gsr muffler. i hear 3" is overkill for all motor setup but some say if your car is making good power with open head it may be a benefit also.. another question i had is if the stock muffler would rob some of my hp also.. any experiences or dyno proven results would greatly be appreciated.. thanks

 

i would say 2.5 for your setup.
i think 3 inch is for some real good NA power

 

i personaly plan to go only 2.5 on my b16. People will talk back pressure and what not. My theory is 2.5 is gona cost cheaper then 3.

 

2.5'' makes good power and isnt as loud as a 3''

 

kteller's bolt up exhaust, is it 2.5" i.d. or 2.5" o.d.?

who else besides t1r makes a 2.5" i.d. exhaust?

 

would i benefit from using my aftermarket muffler rather than the stock one? thanks for the replies

 

the reason why im asking is that i want to have that stock sleeper look but i dont want to lose hp also.. hah

get an es oval muffler then. it's flat black. or paint whatever muffler you get black.

 

2.5 for sure.

yea the muffler i have right now is painted flat black.. hah but im wondering if i would loose any power bottlenecking my 2.5 piping to the 1.5"? muffler. the reason why i want to use a stock muffler is because im predicting my car would be kind of loud because im going to have it piped straight under the gastank and with no cat.. thanks

 

get a resonator and es oval muffler. what's the point of running without a cat. if you just gonna bottleneck with a restrictive stock muffler?

 

keep the cat on....cars stink without them! and they sound alittle more ricey without one

 

is it better to get a 3" muffler inlet and outlet with a 2.5" piping running to it?
