i am going to either get this http://www.mufflermall.com/index.php...roducts_id=742or http://cgi.ebay.com/ebaymotors/OBX-U...spagenameZWDVWim trying to find out if i get the obx will the muffler shop be able to weld it on because the inlet is 3 inches and which one is probably better out of the 2

 

I would think that the muffler with the 3" inlet was designed for cars having larger engines than what we have. Therefore, I doubt that the larger opening will translate into more horsepower or better sound.

That twin loop pipe does look strange on a muffler.

 

twin loop mufflers are great i love them. just i wouldn't reccomend the obx, i've heard some pretty crappy things about them on this forum. just for your information, in case of anything.. piping should always on an n/a civic be 2.25 inch.

 

How much HP can you gain from that?

 

a whole lotta nothing

 

2.25 inches?...why not 2.5?...and i think the 2.25 inch is what causes that "ricey" sound, when i put on the video of performace from my car before the k20 swap u will see how it sounds very much like a mustang

 

I think my Magnaflows have 2.25 piping and they don't sound ricey at all.

 

i will put up a old video of my exhaust that i found on my pc and u tell me if it sounds good and the piping size
