I'm getting an exhaust system for the H22. A custom SMSP header. Test pipe, then the cat back. I'd like to get maximum gain while maintain the quite. I know it's impossible, but of these choice, which one would you guys suggest?

1/. Apex'i WS2
2/. RS*R Exmag
3/. Greddy SP2
4/. 2.5" mendrel pipes with Magnaflow Resonator (22" long) and Magnaflow Oval Muffler. All are 2.5" straight through.

Options 1-3 have 60mm pipes while my header has 2.5" collector.
If you choose #4 setup, which muffler would you get?

a. Stainless oval 5"x8" @ 18" long then weld a tip on the 2.5" outlet



b. Stainless oval 5"x11" @ 22" long then weld a tip on the 2.5" outlet



c. Stainless oval with tip, cut the 2.25 inlet and weld a 2.5" to the muffler 2.5" internal core:

this muffler has 2.25 inlet, BUT with a 2.5" core, and a 7"long, 4"diameter tip.


Edit: Mods, can you help me add a poll for the following options?

Any muffler thats straight through will be loud...espeacially if you have a cat back with out a res. the res cuts noise just as much as your muffler. The cat doesn't cut noise (maybe 5%) but helps performance if your boosted or really well built. If your really concerned and have a little extra cash, I would suggest a double pass Mugen muffler. Its not a straight through muff but acts like one and cuts the decipals to almost nothing.

 

Mugen doesn't make one for a 5th gen accord, i think.

I thought of the mugen design. It's pretty much the idea of loooping the sound wave back to the immediate damping and thus able to reduce the sound twice as much compared to the regular method. that's why I though of installing the resonator just a bit before the muffler. That way, the sound waves will not be able to dense up like they were and will be a bit less noisy than when the resonator is normally put so far away. :dunno: it's just my thought, might work, might not.

 

RS*R Exmag > *

 

RS*R Exmag is hot. and it's not loud. neither is the WS...but, someone correct me if I'm wrong, I don't think either has a straight-thru muffler.

 

that and i didnt think the WS was stainless but the exmag is :thinking:

 

I don't know about the WS2, but the RS*R Exmag on my coworker 240sx is a straight through. I don't believe that there is any damping material either, the muffler body is pretty hollow, where the 2.5" inlet enter a BIG emty chamber then exits through a 2.5" outlet, if I remembered correctly.

 

 

i dont liek the rsr design...that "lip within a lip" look.

 

q-u-i-e-t h:

i vote for the WS cuz i loved mine on my civic and my teg.
