yes i like the N1, and as for the question being subjective, ah well, your right only "you" can define what you like, but at the same time people come to conclusions by deciding their own decision amongst opionions by others. So by typer_r6 asking a simple question, he can broaden his knowledge of what his options are and make his own decision, no need to dogg him, that's all i'm saying, i don't like negative feedback, so i'm just trying to look out for others, i'm not trying to offend anyone, sorry if i did.

 

Who dogged him anyways? quote me an example of this dogging.

 

Wow, a little scuffle on ITRCA. Haven't seen much of that at all. :P

Anyhoo, I must disagree with you mr. fred toast.

I interchange my test pipe and cat often, and the change in volume is ... non existent, zero, none, nothing. I do have a fujitsubo rm-01a, which is neither loud nor quiet (just right in my book, mellow yet agressive?). I noticed a) no change in tq/hp on the dyno between the two (only change between runs on same day) and b) no change in volume.

The ONLY difference I have noticed is a slight different sound when VTEC engages. The change in exhaust sound seems to be more pronounced when the test pipe is on, but as soon as I'm past the engagement point, the sounds are almost identical.

Now, I understand that other exhausts may behave differently. My experience is that a test pipe is only good if you run on the track and don't want to put extra strain on your cat. Then again, tuning AND running a cat will help to prolong the life of your cat tremendously.

Anyhooo... exhausts.

I, like dave, would NEVER put an N1 by apex'i on my car, ever. I hate it. It's obnoxious, the kind of obnoxious exhaust that is well suited for a track car. :P I do not like any exhaust that 'buzzes' or is simply loud all the time.

I have driven a mildly built GSR (skunk2 stage 1's), oem jdm 4-1 header, t1r bpipe and spoon N1 axleback, and I will say that I liked the sound alot, much like my fujitsubo from what i could tell. maybe a tad louder. maybe it was the same volume in the cabin because of the rear seats and the sound deadening that my car doesn't have!

Anyhoo... lots of exhausts, they all sound good to someone. It is all subjective.

AND.... sound clips of exhausts all sound the same IMO. Nothing beats hearing it live, in action, and then driving the same car to see how the sound is different when in the car and out of the car.

Anything is better than open header. Even the buddy club spec II and III. :P

 

I've heard this before, but when I look inside a cat I can't believe that it wouldn't effect the flow. Of course I've never used a highflow cat or compared them on a dyno, so my opinion doesn't mean that much. The main reason that I didn't get a high flow cat was the cost. They are very expensive, and don't last very long. So I replaced mine with a small glasspack ($25 plus labor to weld on flanges). Luckily no emissions tests here in Tennessee. My stock cat was all f***ed up. I had been running very rich (and boosted) for 30K miles. I was already getting code 67 when I had it replaced.

 

I personally like the sound of the MUGEN Twin Loop. It Nice and Deep.

I didn't feel that anyone was Dogging the person who started the thread. Not at all. What was said is absolutely TRUE!! I like Low and Deep Tones, while the other person likes loud and open tones, Some like the High Buzzing of the N1

One comment that caught my attention was about the Spoon N1. Is this exhaust really not so annoying? I like a deep tone but my Stock exhaust is kinda quiet for me. I mean She howls when you step on it and it sounds nice but it's kinda quiet for me comming from a Civic with a Dunk exhaust.
The Mugen Twin Loop has a Straight through design but with a feed back loop to preserve the torque usually lost with a high flowing Straight through design.

 

I love my Mugen TwinLoop. It has a nice deep sound, but just barely louder than stock. In fact, it is almost TOO quiet for my taste. Chalk me up for another one that doesnt like the N1 sound. About the only other exhaust I would consider is the Fujitsubo like on Chris N's car. I dug it! Like he said, nothing beats hearing them in person, in/out of the car...the Expo was great for that!

 

I have a Thermal, and it actually doesn't sound that bad. I don't think I've heard any four banger and said "wow, nice sounding exhaust". The greddy evolution is probably the nicest sounding exhaust i've heard so far.

 

you guys want a noise increase with a stock exhaust just get an ATS Final drive. makes a much bigger performance difference than an exhaust

 

I must take back a bit of my statements.

At the time I did the dynoing with the hi flow cat and test pipe, I had a JDM DC 4-1 header. No change in power, noise, nothing.

Well....

I put my test pipe back on last night. I had been getting code 67's: One week it would be on, then off the next week. This happened for two months, every saturday it would go on/off! Weird.

Anyways, I now have a toda 4-2-1 and a mugen intake.

Well, um, hrm... my car is MUCH louder ESPECIALLY in vtec now. It screams, growls, snarls. I'm confused. The power is a bit different, I can feel a change, i'm not sure for better or worse, just different.

So. I have no idea what I say about test pipes and cats anylonger.

I refuse to believe that with one header there is no difference, yet with a different header and intake the test pipe would behave so differently.

Me - stumped....

 

The sound clip of George Knighton's SMSP header/cat/exhaust combo made me say, wow nice sounding exhaust. My friend also has a custom built exhaust using Magnaflow stuff - no cat and 3 resonators and it soiunds pretty good
