Guys, I don't intend offense to anyone, but unless this actually produces a functional gain (i.e., power), this mod is rice, pure rice. It's a sound-only mod; the auditory equivalent to plastering stickers all over your car. All show, no go. Like a Toyota Tercel with a fart-can exhaust and a huge rear wing. Having said that, will it produce any real gains? I highly doubt it, personally, but we really don't know at this point. We need to have a before and after dyno test performed to know for sure. Again, I'm not trying to offend. I'm just calling it like I see it.

^ true, but for those of us still waiting to replace our stock exhaust it still could be something fun to screw with to pass the time

While I do agree that there is likely not much of a gain to be had by deleting the muffler...there is, however, quite a bit of weight savings in dropping that thing off the *** end of the car. Now, it's not dropping weight where we would prefer (front end), but it is dropping weight none-the-less. No HP gain but a reduction in weight is still considered a performance increase.

Lol...I did this to the Range, would you call me a "ricer"? If it does sound good, what's wrong with wanting it without spending 10x as much?

No, I'd call you a poser. But it's the same basic concept as a ricer. This mod is all show, no go, that's what's wrong with it. It's about making your car sound more powerful without actually being more powerful. I could be wrong, but nobody has done a before/after dyno to test for gains. But that's no surprise, because posers don't care about real gains, right? So why would a poser go through the trouble of doing dyno testing? Anyway, like I said, I'm just expressing my personal opinion. We can agree to disagree. If this "mod" floats your boat, more power to you. Maybe for your next mod, you can fake having a six-pack like this guy:

semtex your mentality is actually the pure definition of ricer.

Not to get into an argument on the internet, but it really didn't make sense to get a full exhaust system on a car that already has 400hp and weighs 6000lbs, where a 20 HP gain means almost nothing. It sounded really good how it was, and I just wanted it louder...so that's what I did. I didn't even know you could rice out a $90k car. On the Z, however, if I mod it it's because I want it to be faster...so I will spring for a real exhaust mod. Money is obviously not an issue for me, but value is. $100 to get the sound I want, versus $2000 for the same sound and maybe 10whp?

Maybe one day you will learn a little bit about the value of the dollar, but until then the only real poser is you buddy....

Wow, you could not be more wrong on everything.
The point of modding is to show respect for your car (a), and to do what you like (b). Now it is your car and I have no matter in telling you what to do, but I would hope buying a 90,000USD car and just doing a muffler delete you would understand how stupid that is.

Also, where are you getting your numbers from? 2,000USD for an exhaust system that gains 10whp? I dropped under 1,000USD and the exhaust has proven gains of 15-20, many are dropping at most 1,500USD and getting equal or slightly better gains. For less money and far more gains than what you seem to claim to. The value of money seems to be wasted on you, why did you spend 90,000USD just to devalue it with a cheap modification? Come back when you have a valid counter point and not just grasping at straws.

the stock muffler is so huge but does almost nothing for the noise......damn those cats...lol

CBRich · 06-03-2009, 09:35 AM

I agree with you Semtex. I think most people are just amazed that it doesn't make an atrociously terrible sound. I wouldn't think for one moment to do this but I'm still really surprised that it actually results in a somewhat decent tone.

Oh I agree about being surprised that it doesn't make a terrible sound. Don't get me wrong -- like I said in my original post to this thread, I think this little experiment yielded some valuable information, and I'm glad batman_4 did it. Specifically, if we remove the mufflers and it still sounds reasonable, I think we can infer that the stock cats are really, really restrictive. I think we've all pretty much known that for a while anyway. But this just confirms our belief.

Stock exhaust has 2 cats, 2 diffusers and one muffler. I don't think it's neccesarily fair to say it's the cats cutting the noise. You've got me curious enough to unbolt the rear section of my stillen exhaust to see if it's the cats or the diffusers....

Sure, you only gain 10hp on 560, but it makes such sweet music. It's a more satisfying mod than removing my Bose sub and adding a 12" speaker and amp. To some it's just noise. To me, it is music. Unfortunately inline 4's don't sound like music unless they spin faster than 10,000 rpm. For that reason, my Yaris, which is lowered, has aftermarket swaybars, shocks and Momo wheels, has a STOCK exhaust.

Yeah, I have to admit that I neglected to take the weight-savings aspect into account, so I guess it's not entirely rice. I still think it's a poor substitute for getting a proper aftermarket exhaust though. Just my opinion.

Replacing just the stock cats with HFCs and leaving the stock cat-back in place produces a significantly louder exhaust note. DDMotorsports has a vid clip showing this. From this alone it's obvious that the stock cats are having a noise-suppressing effect. Are you suggesting otherwise? That the stock cats aren't cutting any noise? Yes, the resonators are cutting noise as well, but if the stock cats didn't cut any noise, I don't think the HFCs alone would produce as dramatic an increase in sound as they do.

I agree, but it's a personal opinion. Some people really only enjoy the sound that the exhaust gives and don't mind if there are no power increases. Just wanted to point out the weight factor since weight reduction is definitely a big topic for the track.
