ok so i was wondering, i had my old vw jetta without a resonator and a cheap weld on muffler and it sounded nice but it was kinda drowning at times, now i was wondering on the fit instead of cutting it out and making the thing hecka loud is there anyway to put like a straight through resonator so it will sound just a little bit better? i havnt been to any muffler shops and asked but i want to find out from anyone on here that has done somthing like this or has any good ideas.
I know what you're talking about with VW's and taking out their resonator, I had a Mk4 Golf 1.8T before the Fit, and a lot of people were doing this as a 'cheap' exhaust mod.
However, over here on Fitfreak, the 'cheap' exhaust mod would be to replace the axleback with a straight pipe. Its cheaper and its reversible! As for sound, it is not hecka loud, but people will know that your exhaust is not straight from factory.
taking off the muffler isn't a good idea.
the EGR might throw a code because of the enormous change in flow.
same goes for removing the resonator, you'll easily break the decibel limit and you won't see that much of an increase in anything in particular.
remember we are driving econoboxes even a catback wont give you much.

hahahaha you are trippin if you think taking off your muffler will throw a code. i have a turbo, a straight pipe into an s2k muffler and the only code i get is from the intake side map sensor reading wayyy too much air being forced into the engine. anything short of running your car without a header and you will be fine.
taking off the muffler is ghetto, considering that you can find a good axleback for the fit for around 100 bucks. before i was turbo, i had an aspec muffler and a T1R bpipe. it sounded pretty good but ive heard NA fits with a straight pipe and it sounds straight up like a bumble bee.
Well i kinda would like to keep the hfp muffler. I mean i did pay hecka bank for it. I love the way it looks and i sounds pretty good but i thought maybe something would make it sound a little bit different. A lil stronger. But if replacing the res isnt the way to go then i cant do much more. Also the reason y i wana keep the hfp muffler is bec i dont know how to get anything for it bec its used and theres no fits that have anything done to theres down here

you two are skeptical but the ECU is designed to measure this exact thing.
from what I know "learning" or "smart" ecu's in our fit measure the exhaust flow,
so removing your muffler is the same as having a piping diameter above 3" on an NA car.
it throws off the small bursts leaving your engine, especially at a higher RPM (usually MT), allowing some exhaust gases to be pushed back into the engine hence the possible chance of throwing a code.
i drove around with my muffler off for two weeks and didn't have any EGR codes ... however, i didn't like the sound AND i lost power.

if you decide to cut out the resonator you might consider having the muffler shop modify the HFP axleback to sit a little higher:
it's a matter of personal taste, but i think it looks so much better with most of the HFP muffler body tucked behind the sport lip. also, no bumper roast. the owner of that TWB Fit has been running this same exhaust set-up for almost 3 months now.

haha ask any ASE certified tech. about it n__n
wow. you are talking out of your butt. our ecu's dont measure "exhaust flow" it measures the air to fuel ratio by way of o2 sensor. converting the amount of oxygen in the exhaust to a value of current so the ecu can make the proper adjustments in fuel/timing. you will lose torque, but your car will NOT push exhaust gasses back into your engine. and if it does, it will just be pushed back out in two seconds through the next cycle of combustion.
okay i am done arguing with people that dont know much about cars on fitfreak so believe what you want. i suggest you go buy a service manual and read it cover to cover so you can make informed statements rather than saying what you "think" is right and stating it like fact.
haha thats why i said from what i know, i'm stating what i know to be true.
and you say that the gasses pushed back into the engine will just be pushed back out in the next cycle well its not that easy or healthy for the flow/pulses to be disrupted like that, that is why exhaust piping diameter (and length!) plays a huge role in performance and efficiency, to remove the muffler or create a "muffler-delete" can vastly increase the size of the vacuum behind each pulse throwing more and more back into the engine especially at higher RPM's.
the OEM and aftermarket companies were not just slapping on whatever looked and sounded great past the b-pipe, there are mathmatics that go into it.
you know that the ECU is responsible for throwing codes in our fit, a disruption in exhaust flow (pulses) usually prompts an error regarding the EGR due to the new amount of gases taken back in, pls do look it up on any new gen car forum.
i do honestly have the utmost respect for you being an extremely long term member and one with great reputation, but i wish that you would retort with intelligence rather than flaming my post altogether; it shows little to no respect for your fellow member.

i apologize. i am just getting fed up with correcting simple misnomers that some people post on fitfreak, and your post just brought me to the boiling point. you just caught me on the wrong day at the wrong time. i didnt mean any disrespect.
you are partially correct with the above post. exhaust pulses/flow play a HUGE roll in performance. any respectable tuner will explain to you that the exhaust pulse should create negative pressure effectively pulling exhaust fumes out of the tail pipe and not letting them linger. and i agree that putting a straight 3in pipe on an NA car is ridiculous and will result in a loss of power. but you really dont effect the back pressure all that much with anything after the catalytic converter. remember, the sensors that are reading and calculating the amount of air to fuel dont read cfm values so you have to rely on a tuner or yourself to monitor afr and make sure that it correlates to the power being made.
so all in all, the ecu is not reading exhaust flow but rather the density of gasses in the air being passed through it. disruption in the stock exhaust flow parameters has little to nothing to do with any code that will be thrown in a fit. you can find the testament to that with the numerous people on this forum who have changed the exhaust piping design with little or no issues.
i'm glad we could settle it like gentlemen, and stop thread jacking this guy's post.
it seems my conception of this was a touch off and into left field
hey well uh... if you're looking for a slightly louder muffler.. im selling my A-Spec... for super cheap! haha
oh btw if you are willing to spend some money, just buy a B-Pipe. With the HFP it's so nice. Low rpms it's very standable and quiet but the higher you rev, the louder it progressively gets. very nice!

Your selling the a spec b pipe or just the axle back? I am looking for an a spec b pipe. PM me if you have it for sale

i would buy it but i dont like how its painted black, i would have liked it way better if it was chrome like it was before you painted it, also why are you selling it and what do you have on ur car now, also i could just get the lsd muffler for 159 shipped for the same exact muffler.
cuz i have a HFP now, an A-Spec in conjunction with the B-Pipe was a bit too loud during freeway cruising. Haha i was about to paint the whole thing black but i left the Tip. i originally wanted only to paint the inside of the tip because it was fading but since i had so much paint left, i just did the whole thing

o i c, ya so you have the hfp and what b pipe? megan? aspec? i wanna get one and keep the muffler but i want to hear it first, is there any possible way you could post a video of what it sounds like for me?
i have a Megan racing one. mm i cant really record a video since i use my phone and there isnt a stand for it. come by our meets if you live in so-cal, you're more than welcome to hear it there, if not, i'll try to make one if i can get someone to record 4 me
... however, i didn't like the sound AND i lost power.
