Can i swap a b16a from a 92-95 SiR with an aftermarket stainless 4-1 exhaust mani into an eg hatch and hook it up to the stock cat catback and muffler and keep it relatively quiet? Im not sure if they would easily bolt together, and if they do, what the sound level would be. I have a lot of other plans beyond the swap and would rather not buy a whole new catback, resonator, muffler, etc.

I have a 95 ej1 with a stock exhaust mani, magnaflow high fow cat, 2.5" catback, and a cheap off-brand muffler on. Its rather loud and when passing cops they tend to follow, which resulted in a few rather bad situations. So im looking to run a quiet exhaust on a hatchback project with a b16 swap.

 

The muffler is the main culprit of noise. So if you kept the stock one, it should be relatively quiet still.

 

If you put the b16 in and put a stock cat back on it, your car will be stock level sounding. its very simple.

 

A performance header with stock muffler does keep the car "quiet." However, it may sound like a bunch of angry bees when you gun it.

 

Or just find you a newer Si muffler.
Looks good and its quiet

 

x2 with newer factory muffler..your resonator quietens things down a bit too.
but honestly i'd rather have a nice easy flowing loud exhaust then a restricted quiet one. but whatever floats your boat..

 

well im not much of a fan of loud mufflers bc it was my muffler that attracted a cop that arrested me 4 days after christmas for street racing, when i was in fact, not. I was merely behind 2 cars that were racing on the local strip (one was my friend), and i had a passenger in my car filming the whole thing (the race, not when the cop came). Long story short it lead to a whole court hearing thats still due to come soon and a possible 2 year license suspension, after i just got off a 3 month suspension.

Kind of a dumb reason for wanting a stock exhaust if you ask me, but im rather sick of the local cops following me. Theyre ******** that, when passing you going the opposite direction, WHIP around in an illegal u turn, even if it means going into someones grass, just to follow me. Even when i am in fact doing the limit. I do know the one officers name and plate of his usual cruiser, due to him pulling me over unnecessarily once. Ive tried doing something about it but theres not much you can do.

 

Stock exhaust should be quiet as stock on your setup unless you have a really crazy header.

I don't know about your particular car, but on some civics, you have to rotate the front cat flange 90 degrees to match the bolt holes to the header, and add about 3" of pipe to the front of the cat to keep it from rattling. I had to do that on my 2000 EX with a gsr swap.

Other than that, they easily bolt together. Before you put the motor in, just look at the flange on the header and the flange on the cat and make sure the bolt holes line up. Otherwise you have to cut and rotate one or the other.

So am I, a big fan of WS2. However, that large can look will say "Pull me over" even if it's never said a word. Guilty just by the look.
