anybody ran their car w/out the stock muffler??
#161
So I've ran the Fit without an exhaust for awhile and I loved it, I was constantly paranoid about the exhaust leaking in though and so I decided to get a HKS Hi-Power exhaust. What I noticed is that they sounded identical!! So if any of you guys are unsure what your car would sound like with cat-back or a performance exhaust just take it off and see if you like it

Last night as we installed my Progress springs and rear sway, I started it up to see what it sounded like and was amazed at what I heard. So I leave it off and find this thread today. LOL it's staying off and I'm NOT adding a straight pipe anytime soon. I wish I would have found this out sooner.

as cool as it sounded like without a muffler. Today i decided to put mine back on due to the fact that there is a risk of burning the valves. And i'd gladly sacrifice sound over valves lol. I guess its okay cause now i get to save up to buy the HKS Hi Power Exhaust

Less weight and nice deeper tone - when you see your depressed bud threading a rubber hose through the back window start worrying about fumes, if you're out in the open and moving around how can fumes get into the cab?
One thing I kept my eye on was the rubber brake hose, which is quite near, but no problems there either.
I don't see how removing a noise-suppressing muffer would damage valves - they just flap lift to let the exhaust gases out, what do they care if it's loud or not?
Take it off! Take it off!

I don't think there's going to be any risk of burning valves, warping valves, or contributing to the delinquency of valves. There's too much exhaust system downstream of the head and even after the converter to expose the valves to enough cold(er) air for them to cool unevenly. That's what causes valves to warp - uneven cooling - and you usually find that happening on leaking exhaust manifolds or headers. If the manifold gaskets (if used) are sealed, the valves aren't going to warp. How many thousands of drag racers are out there with nothing more than a header downstream of the head, and those valves don't warp.

well after reading up a bit more and from reading what you guys had to say. I took my exhaust back off. Guess i loved the sound to much. Oh well one day i'll have a "real" exhaust. but that'll come after lowering springs.

Going in to the muffler, or going out? The outlet is close to 1.75", and the inlet side is like 1.667" or so. I measured those points a while back and can go check them if you need super precise numbers (I used a caliper).

Anyone have any back-to-back dyno output to confirm that there's less TQ without the muffler? I tend to think that's basically an old wive's tale that MAY have had some truth back in the carbureted days. If a car was perfectly tuned with a restrictive exhaust back then, uncorking things would help the engine breathe, so the mix went lean with the unchanged carb setup. That WOULD lose torque. We (and virtually any other car with an injected engine) don't have that problem.
If an engine can be adjusted to take advantage of the improved flow, it won't lose power at all. Anything that helps get air in and out of the engine will make more power as long as the fuel & spark is adjusted properly.

Thanks, that'll do!

Just get under and you'll see - you need a 12mm spanner, and you then twist the muffler brackets out of the rubber holders.
If you can insert an ignition key and turn it, you can remove the muffler; that's how easy it is.

ok nice upon posting my last post my friend said that removing the muffler can cause serious consequences ... like emission detectors in california can give me tickets ..... is it true wats the negatives that will result from removing it guys :T ?

I took mine off just to see what all the hype was about....not bad at all!!! If you think about it, the mod should give around the same gains as a axle-back....maybe even more due to less restrictions. No way to tell until someone steps up and dynos.
As far as burning valves or warping valves, if that was a side effect of a more free flowing exhaust every single person with an upgraded exhaust would be replacing their engine...funny though, I have never known that to happen....and if it did, don't you think there would be tons of class action lawsuits? Myth busted!

Just read this thread and walked outside, undid two bolts and drove off. Sounds great. not really loud by any means. very quiet at idle. Nice low tone at half throttle. no fumes. However, i did go offroading in a friends old hoopie suburban w/ an exhaust leak in the cab and actually fell asleep. not fun. And for all the haters in this thread, Can't knock it til you try it. nuff said
