Well as you all know, I ahve the Apexi WS2 and I dont think it is loud enough. So after noticing the screen metal gaurd in the actual muffler I decided to drill it out and maybe it would be a little louder. The metal gaurd is doing the exact same thing as a silencer anyways. So I shine my flashlight in there and notice all the holes are plugged with a black stuff which dad and I thought was fiberglass but oh well!

Anyways, I bought a 12' extenonsion and a 12' drill bit for metal and I only have an inch or two to spare! So I began nervously drilling away at the gaurd and had about 5 holes in there. I started her up, and it sounds the exact same. So I stuck my drill in there again and noticed that there is another piece of metal ab out 1/2 to 1 inch behind the gaurd that I just drilled out. So isnt the WS2 muffler a straight through design? If so, I should be able to drill through the next piece of metal and not have to worry about drilling out the muffler or piping. I tried it a bit and it seems thicker than the gaurd I just drilled out.

Do they have a not so straight throguh design? Is it okay to drill out that metal?

I am assuming the muffler is like:
(Inlet) 0 I I 0 ---->
with the I's being the two screen gaurds.

 

couldnt you ask the mfgr for a cut sheet of it? i diagram may help before you totally chew it up...

not that i havent done stuff like that before.

 

Good thinking...thank goodness for other members! hehe
I just hate waiting for replies from manufacturers[:'(]

 

np. when in doubt, ask for help from those who made it!

 

Grrr, they dont have an e-mail address and they are closed right now.

 

prolly better they dont have email...better to speak with a real person.

 

the n1 is straight ws2 is chambered.
but yeah talk to apexi before modifying their product. they could tell you more than any of us.

 

hey accord, so the APEXi WS2 Exhaust is not that loud? But does it give you a boost in performance? How much did you get it for and where? Any suggestion of places that i can get them for cheap in priceand not Piece of crap on ebay?

 

Nope its not loud at all, I can only hear it at startup and I cant hear it over my intake.. It did give me a nice boost in performance, although I put on my header and WS2 at the same time.

I got it for $430 off eBay
Theres other places to get it though, but I found eBay to be the cheapest at the time. Usually no matter where you get it, shipping will be near $100 bucks.

 

oh nice thanks
