I will say add a muffler bearing and back pressure, scavenging, and flow will increase a hundred fold :twisted:

I'm unable to look at the Honda Tech links you currently provided, but to say that a 4" exhaust on a d15b will create more power than a properly sized exhaust is not only a blanket statement but also ridiculous.

companies make 2.5" because of stock cat and street cars. another reson would be cost of product. 3" costs more


look at a real race car one day and ask him why he went with a bigger exhaust.

the less back pressure in the catback will have more scavenging in the exhaust. i dont need hige terms. i understand it and i am a aspiring automotive engineer. some other people will try to tell you whats real. but i know and i found out for myself.

My b16 has a ebay resonator and a ebay header.

Or I could just put the entire exhaust system on my car.


Thanks everyone as soon as I find out Im going to do this because my car is too loud


My car has a B16, stock header, 2.5 cat-back with resonator, and has a stock muffler. The 2.5 inch piping converges as it goes to the stock muffler.

My experience with it is that I can hear the engine rev but the exhaust sounds stock. I've been in some loud cars that had a 3 inch exhaust and it gets annoying when on the highway.

Here is what it sounds like from inside car: http://www.youtube.com/watch?v=VFAZmdOWg_4

I prefer to have an upgraded header, 3.0 inch cat-back with resonator, and a stock muffler. But have an exhaust cut out before the stock muffler.

I have ebay headers, and a ebay pipe that is after the catalytic converter with a ebay resonator. I think the diameter of that is 2.5" Right now I have a HUGE Ebay exhaust.



THANKS, Im waiting on anyone of yall so I can buy the muffler because I need my car quieter or I might get fired!

Yes, putting a stock muffler on your exhaust system is okay...I've had my setup for over 2 years without a problem. You might lose a lil power up top due to the restrictive stock muffler.

It means I want my whole exhaust system to be upgraded...except it would have a stock muffler. But I would have a switch activated exhuast cut out opener that is like running and open exhaust. http://www.youtube.com/watch?v=rPnLAhsnTz4

Would a RSX Type S stock muffler fit?

I didnt find any b18 stock mufflers for sale on CL but I did find a RSX type S muffler.


I remember when I was looking for cars I test drove a EG with a RSX muffler and it rattled because it was too long and he needed to do something to get it fixed.

I'm not sure a B18 stock muffler would be better. I never came across one. I would assume the stock muffler would be a lil bigger than one from 1.5/1.6 liter civic.

For the fitting you would have an exhaust shop do that part. The stock muffler inlet piping is smaller that 2.5 inches.
