Will this custom exhaust soundToo Loud?

[LanEvoBoi757]

Ive been trying to decide if i want to got 2.25 or 2.5 for a while now. This is for an ls integra.

I already have a 4-2-1 dc header
I want my car to be quiet as possible and look stock while freeing up some power.
Im not trying to go all out hardcore racing.

here are my choices
1)2.25 inch piping, stock cat, 14 inch resonator, going to rsx-s muffler or itr muffler
2)2.5 inch piping, carsound cat, 18 inch resonator, going to rsx-s muffler or itr muffler. (I would like to go with this choice but i know the itr muffler is 2.25 so its going to be more restrictive)

Does anybody have 2.5 inch exhaust piping which is really quiet?

i know some of these wont mix well, so throw out some combinations that will work out for me.
Thanks

as long as you have the cat and resonator it won't sound really loud. especially with the S or ITR mufflers, and if the piping on the muffler is smaller than that of the piping that is bad. try to get it all the same

I would go with the ITR exhaust. You know it's going to line up a bit better than the RSX exhaust because it cam of a DC. Isn't the ITR 2.25 also? That would be great if your not looking to go all out or FI..... Try to match everything from the headers to the muffler/out.
