Looking for Moarrr Roarrrr
My fellow Acura owners...I love you all for being so helpful all the time!! :bow:
Ok so I already have the magnaflow catback (mufflers, tips, resonator) and a mid muffler delete. But iv grown accustomed to the sound and I want to make it ROARRRR MOARRRR :beetroot: Any suggestions? Will the rv6 J pipe add much to the sound? What about the hfpcd's? Much appreciated as always! :spank: |
Any pipe upgrades will alter the sound of the exhaust. If you are looking for a lower tone, J pipe will add that. PCDs will give a raspier sound because they are straight pipes. HFPCs will give a nice growl but wont give off as much rasp as the PCDs. Check out some youtube videos of exhausts and use those to base your decisions.
|
J pipe barely changes the sound. What size Magnaflows do you have? Switch to a smaller muffler or up the pipe size.
|
Each Jpipe will give you a different sound. It won't sound worlds different and probably won't add any 'volume' to the sound, but it will give it a different tone. The PCDs will definitely make it much louder and 'aggressive,' but will come with rasp, especially with no mid muffler. The HFPCs will add volume to the exhaust too, but with less rasp than the PCDs because they have cats.
|
if you want more rumble; switch out the fake catback for an aftermarket catback.
|
Thanks for all the responses guys, very helpful stuff!
I dont want to swap out my current setup. I really like how aggressive it looks with the 3.5 inch tips. Just want more roar on acceleration. From the info it sounds like the hfpcs is my best bet for a deeper tone when I accelerate. |

If you want more sound you'll need a catback exhaust. Check out our XLR8 exhausts if you're interested.

XLR8 quads = PURE SEX!!

^^ This. I misread, you only the mufflers and resonator? Get some 2.5 or 3" piping to replace your stock diameter piping for more roar. Your 'staged' exhaust isn't giving you much rumble.
That shouldn't cost much more. Which ones better 2.5' or 3'? How wide is the stock piping? |
Id go with 2.5" piping, 3" you may end up losing torque.

^ Lmao.
I'd recommend 3", but what do I know? :hide:To properly scavenge, you are going to want a Jpipe with a 3" collector as well. Otherwise, I'd recommend 2.5". |
Now im torn between 2.5 and 3 lol I will do more research! Iv seen this 2.5 and 3 inch thing discussed here before...I remember reading that one of them leads to torque loss

in for more info on the 3inch catback.

The whole point of a tuned exhaust is to allow optimum scavenging. To do this you need as much velocity as possible. Now velocity does not mean a 4" pipe, for example your water hose, when it's fully open it pours out slowly and if you cover half of it with your finger the speed increases.
So think of it like this, the pcds are 2.25 inches since we have two that is 2.25X2 which equals 4.5". This has been proven to be optimum under most J30 applications. As the speed slows a smaller pipe is needed to keep the pulses going quickly, this is when the single 3" comes in. That is a 1.5" decrease in size. As you go to the dual exhaust you could have pretty small pipping and it shouldn't hurt power, but at the same time it's so far back in the exhaust the size you have won't really hurt anything (in theory, if I have this wrong please correct it) |

The difference between 2.5' piping and 3' is 1/2 inch. :bitelip:

I'd go with a 3in. though. I'm sure the gains won't be that much but it'll be more for sure. |

Needing back pressure is a myth. It's even more of a myth when you consider the car is on the small cam during most of your 60'. Only 2-strokes and rotaries need back pressure.
Usually eliminating back pressure boosts the midrange and upper rpms more making the low end feel weak when in reality it is not. Scavenging should not be real important since it's a vtec car and the exhaust ports are merged inside of the heads. You could try the Supertrap muffler for adjustable backpressure for testing lol. I wonder if they still make those. For a street car, you should be able to chop the exhaust off right at the heads and not see a loss of torque. |
Roarrrrrrrrrrrrrrrrrrr.
You can't just add the pipe diameters together. You have to get the internal volume of a 3" pipe and the internal volume of a 2.25" pipe. You then multiply that by 2 to compare to the 3" pipes volume. Dual 2.25s is only slightly larger than a single 3" if I remember correctly. So in essence, you should still have a 'venturi' effect going from dual 2.25" PCDs/Jpipe to a single 3". If you are only doing it for sound, just get a 2.5" exhaust. |

go for 2.75". no more dilemma
