I was wondering if anyone knew whether or not all civic mufflers are the same internal diameter? Reason I'm asking is beacause I want to run 2 1/4" tubing from the cat back, but don't want the attention that an aftermarket muffler gets, therefore wanted to run a stock honda muffler.

Any ideas?
Thanks!

 

You could weld on a muffler from one of the higher displacement cars maybe. I've heard people weld on s2k mufflers and love the sound.

 

Get a World Sport, they arent loud at all. I have one and love it.

 

The only thing that's stopping me from that is that the po-po in San Diego will give you a hard time, even if your exhaust is completly legal and compliant with all CA **** smog laws. I've even had an officer tell me that whenever she sees a Honda with a "Shiny Muffler" she pulls it over, throughly checks under the hood etc, and will give them a modified exhaust ticket.
So I'd prefer to keep a stock muffler out the back. You think an Si muffler flows a little better an the stock CX one I have?
Thanks.

 

that's a good idea. surely a 240 hp car has better flowing mufflers than a 160hp car. [s2000 vs 99SI+]

 

the SI should. have you ever heard a civic [motor swapped] with their stock muffler in place? u know the nasty-all-the-baffles-blown-out sound?
i've never heard that from a stock si.

 

I hear it everytime my CX starts up...lol

 

here's my spoon street axleback:



it's the ultimate aftermarket sleeper exhaust. the tip is only about 2.75", and the sound is unnoticeablely nice.

 

somewhat common stock muffler swap would be the ITR/CTR muffler.... they look very nice but have that stock look. or a dynomax/magnaflow muffler painted black...

 

sory to hear your story man. i don't mean to go off your thread topic, but where in san diego did you get stopped? i live in san diego as well, and i have an apexi n1 on my car. i don't want to get rolled by the same cop. thanks man.

 

if ur planning on a 2 1/4" cat. back to a stock muffler ur not going to gain much..since the internal tubing is less than 1 3/4 s..i would suggest replacing ur stock muffler with a alum. mag. 2 1/4" in and out..not the silvery stainless..the alum. with 2 inch tip would nt attract much attention and give u true 2 1/4" cat. back

 

buy an ES oval and paint it flat black or i bought a comptech axel back and painted it black and then cut off the shinny *** tip and just put alil peace of muffler piping on it works wonder no one revs on me at all any more, well the CF hood kinda throws it off

 

I think an ES Oval would be the best choice.

 

I haven't been pulled over yet, my brother has been pulled over a few times by the La Mesa PD. I talked to another La Mesa officer who told me that she'll pull over any import with a shiny muffler. So you might want to keep an eye out for the cops in La Mesa

 

Get the rs-r cat back!!!

 

Stupid popo. I would just forget about the exhaust, no point becasue you are going to run through a stock muffler. So it will be very restricted. Is there any legal mods you can do to your car in CA? Or is driving illegal period.

driving is illegal here in CA. We just fix up our cars and let them sit in the garage.

 

Doesn't a stock 00 Si muffler or GSR muffler flow better than a stock CX muffler? I don't want anything badass, just a little better than the stock butthole piping and muffler.
