I have a GSR engine with the stock header. The header is 2" and im planning of adding 2.5 piping all the way back. Im getting a resonator and a backbox.

Will the sound be ok?
Will the combination of 2" to 2.5" give a raspy sound ?
Will one big resonator be enough or do i need a backbox at all?

 

why do you want 2.5? what do you have done? you're probably better off with 2.25 or 60mm.

 

i want more sound basically.

I have a 1997 gsr with a dc header and a greddy evo and I love it. The evo has a good clean sound with good flow and is not obnoxiously loud.

it will sound fine it all depends on the muffler. But why waste money on an exhaust stay stock

 

if all you want is sound, why not just pick up an axle back?

 

u want sound then go get a ******* pep boys muffler

 

i think 2.5 will not fit on ur stock parts..unless with bottleneck ..go with all 2.5,,cheap mode..Megan header..test pipe..any 2.5 exhaust u want

no, it really depends on ur whp..
2.25 is good up tp about 200whp..if u have less than that and 2.5 piping. u actually will lose some power
