My universal muffler came today.



Here are some pictures of my new muffler compared with my old one.





I have a few questions about getting my muffler welded at a shop. After doing some research, I noticed not all welds are created equal. This thread shows welding can be tougher than it looks.

I know leaks in the welding will cause exhaust noise to greatly increase. This is my first aftermarket muffler, I want to get it installed correctly the first time around. Here are a few questions:

1. My WS2 was supposed to be left offset. I thought my muffler was going to look like this one below.


My muffler looks like this ( O ) when looking at the side that has the large tip. It's dead center.

Is this correct or did Import DPS send me the wrong muffler? I ordered the muffler shown here.

2. The piping for the OEM muffler piping is 4.4 mm around while the WS2 piping is 9.1 mm around. I was not expecting this. Why are they different? I understand this application is supposed to be "universal".

3. How much should I expect to spend on getting my muffler installed?

4. What type of welding options do I have? I rather spend the extra money and make sure I get the best quality welding available. I'm not an exhaust or muffler expert. Any advice would be great.
:D

5. The OEM muffler has an piece of metal with hangers that attach to my car's body with 2 black pieces of rubber. Would it be a good idea to take the OEM muffler to the shop so they can take the metal hangers off and put them on my new muffler? Should I bring the black rubber hangers with me when I go to the exhaust shop?

6. Here is a rear shot of the small tip side of my WS2. Is this correct? I thought the large tip is what should have been affected by offset.



BTW, my cat needs to be replaced because I'm getting catalyst efficiency bellow threshold codes. I heard that muffler shops can replace cats for way cheaper than Honda and their $800 dollar price tag cats. In California, almost any aftermarket cat is not approved. Most aftermarket cats cannot be bought online, I've tried. When getting smogged, places check to see if you have CARB approved cats. I barely passed smog last time. What should I do?

 

looks like you bought the wrong one

they come in many diff offset models

as for fitting on stock factory exhaust.... you should of knew this that stock piping isnt 2.36in. if you bringing it into a exhaust shop to get it welded up. they should have all the adapters to make it fit. but i dont really see the point of doing this with stock exhaust piping with a already restrictive muffler

 

Everything checks out according to the product label on the box and the A'pexi label welded onto the muffler itself. The 156-AO13 product number matches the listed product number shown on the Import DPS site. I'm not 100% sure if the red hatch above actually has a WS2. I have done my homework regarding this muffler. All of the vendors I have spoken with confirmed that the left offset muffler is the one designed for my car.

 

i think the one you have looks more for a 96-00 civic ex, as the ex mufflers come straight back and there not offset

 

My car is a '99 Ex. The oem muffler tip is offset as visible in the pics shown. My guess is A'pexi exhaust tips are never offset. I think the part that A'pexi offsets is the tip that connects to the exhaust piping.

 

universal mufflers outlet tips arnt offset only the inlets...

if you want a offset like that one in the picture. you would have to get teh whole exhaust system from them

 

Any particular reason why you didn't just purchase the entire cat back?
