Thumbs up Oem exhaust mod

Is there anyone out there that has any sound clips of this? I am pretty confident that I will be doing this, but I just want to make sure it doesnt sound bad.

From what I would understand, it shouldn't sound really any different just a bit louder. As long as you keep both resonators and use the one oem muffler, it shouldn't sound different just a bit more volume. Which is exactly what I am looking for.

I love the way my exhaust sounds with the berk test pipe, but I just find that I wish it was a little louder. So I am hoping this is my solution and maybe even using a CR muffler as opposed to my ap1 muffler. (no twin loop)

Also I am sure that dropping one of those mufflers and that little bit of piping will be good for 15 lbs or so. So to me if I can lose 15 lbs off the exhaust and get a little more volume out of it, then that is exactly what I would want.

Any thoughts guys?

I say go for it! The stock mufflers do such a great job that taking off 1 shouldn't really be noticeable. The stockers weigh a TON! I'm sure that you could shave off half the weight by going single.

Thanks! Yea I am thinking it will be a win/win situation for me. It would probably be no more than $100 and it will give me a little more volume and drop weight.



I am not worried about any power gains @ all, but I may even gain .5 hp on the top end being that the exhaust is flowing mostly straight! lol but who cares about that.

a few years from now there'll be more people with more creative ideas as s2 depreciates more.

wouldn't the pipe be too small? I thought it got smaller after the split...

oh shizz! he's right. You'd get less flow as with "Y" setups, the two pipes are smaller as to not cause turbulence and keep the scavenging effect going.

Guess you might have to do custom piping before the spit to the muffler but it would still taper down right before you enter the muffler

lame, you would have way less flow with just one smaller pipe and would loose horsepower. I don't see how this makes any sense.

Just cut it off before the split, would save weight and make more power

Yeah just removing one section will cause you to lose a bunch of power. Will be super small piping going out for a single..Need to replace all the piping from the Y split back.

I didn't realize this! But with this information I would imagine that I would need to replace the muffler as well as the piping then correct?

Because lets say with the stock exhaust the piping is 63mm before the Y-split, and after the Y-split it goes to 50mm piping. That would mean that the muffler would be 50mm as well right? So in essence I would have to replace the piping and the muffler to something with the correct diameter?

Does that make sense?
