First i have done lotsa searching on the forum and at se-r.net

I am confused about resonators also known as glasspacks right? I know that the courtesy b pipe has a resonator on it, but if I am looking for a quiet highway suitable exhaust I will need some kinda long glass pack resonator, RIGHT? Straight through perforated right? like a magnaflow? i've heard a thrush is not as good but cheaper... right?

If i am going to need a long glass pack would it be silly to pay for a mid pipe or a cat back system? Would i be cutting off half of the mid pipe to but on the glass pack? If so, would it make more sense to just go with a costum exhaust since it sounds like things will need to be pieced together?

My cat is on its way out. so i'll likely be purchasing a high flow cat as a replacement, which i know will make the exhaust louder. What im looking for is an exhaust that has a nice sound, that gives me just few horses, and wont kill me on the long highway trip to and from college. If you could make a reccomendation on a brand of muffler, glasspack, cat, custom or cat back system i'd really appreciate it.

You're definitely going to need a resonator if you want it to be quiet, probably better off going with a magnaflow resonator, the glasspacks dont last long at all.

so there is a difference between a glass pack and a resonator... cool.... please excuse my stupidness.... so i'd guess that a resonator is a long perforated tube on the b pipe, yes? if so does the courtesy cat back system have a resonator like this? would it be sufficient? i've heard that the courtesy was a bit loud. So am i talking custom exhaust?

well glasspack usually refers to a cheaply made red painted resonator..a glasspack is a resonator, just a poorly made one.
the courtesy midpipe comes with a resonator, but I too have heard it is loud. GReddy exhausts are quiet, although they are expensive.

so what if i get a high flow cat replacement, into a long 24" perforated resonator, into a magnaflow muffler? seems like that would be quiet.... question is... what would i use to connect the resonator to the muffler? custom bend? would i actually have to buy a b pipe if i would be cutting that much off?

and what brand makes a perforated resonator that isn't a cheap glasspack that will die out on me quickly? i thought dynomax made one but i dont see a resonator that long on their site www.dynomax.com

Thanks for the help

As an owner of a Courtesy/Top Speed catback, I can tell you that it does have a resonator and it's still loud. I'm used to it, but I could see how some might not enjoy it.

If you are fortunate enough to have a local shop fabricate a custom S.S. mandrel bent exhaust for less than Courtesy's or Greddy's exhaust, I'd go that route. Initially I tried, but gave up when I found out most shops in my area delt only with crush bent tubes and the few that used mandrel tubes wouldn't give an estimate.

thats cause san joe. is expensive as fuck...lol

how big the the diameter of the courtesy b pipe..
is it 2.25 or smaller..


hmm i was thinking about this..

but right now im using a magnaflow 24 inch resonator and a 2.25 bent to classic bends tubing.. so that i can remove and install my stock exhause if i wanted .. also the greddy for the b13 is super quiet.. unless you punch.. thats when it really growls..

its purdy.. i have one on my 94.. and the custom mandrel bent piping is on the 91the magnaflow resonator still gets loud.. but its very suitable for highway driving.. i like it.. and it doesnt drone either.

hmmm seems like your giving me some useful advice sr20kidD...... i just have to make sure i hear what your saying........

You were saying that on your 91 sentra you have a magnaflow muffler with custom mandrel bent piping? is the 24 inch magnaflow resonator on this exhaust system? or are you saying that the custom mandrel bent piping with the magnaflow muffler is quiet enough even without the resonator?

I hope its quiet and not too loud cause I am getting that same exhaust system this week maybe tomorrow tell u how quiet really is.

I just bolted a Courtesy cat-back on my 93 and a Greddy SP on my 92, which replaces my Stromung mid-pipe/ $tillen muffler setup.

The Courtesy is a beautifully-made piece: all stainless steel, neatly welded and polished to a mirror finish. It's pretty loud, my car will set off car-alarms wherever it goes. Also, the pipe-diameter is a little too large if you only have simple bolt-ons.

The Greddy is nicely made and really quiet, yet it still sounds nice when you floor the paddle. My favourite out of all three.

Degree of loudness:
1. Courtesy
2. $tillen/Stromung mid-pipe
3. Greddy SP


Hope it helps. :)

the HKS kit quiet. i heard it on a 91/92 SE-R w/cams. very low key both look and sound, i think it is more quiet than Greddy.

i got the Apex N1 w/ 2.5" pipe. LOUD!!! but sounds great.

no no..my 91..has a 24 inch magnaflow resonator...
custom 2.5 and a bomz exhaust..
when i turn the car on.. it rumbles... you can hear the put put put of the cams... then when its all nice n warm.. its quiet.. its only loud from like 4 and up when your coasting highway on 5 gear.. its a very very low rumble.. it purdy..

If you could make a reccomendation on a brand of muffler, glasspack, cat, custom or cat back system i'd really appreciate it. If reasonable noise levels are a priority and ya want to do this ONCE, HKS cat-back is the way to go.
It’s hard to comment vs stock as i replaced a dinky CarX and not OEM, but compared to other systems heard at meets and such the sound is sweet and subtle. At anything more than ½ throttle the WAI is louder.
I had a shop pop mine on since i also needed to flange the Catco and put some hangers on it. It seemed to bolt right up. If i only needed to replace the exhaust i prolly would have DIYed.
NOPIonline lists them for $445, which might be the best price out there next to Courtesy, $tillen and PaceSetter. Then again the cheaper options are all louder (prolly lower quality for the last two as well).
As a bonus, i love the look. As if someone grabbed a single tip Maxima muffler and threw it on there. Again, very subtle, very nice. Look at the SE-R portion of the sig site for some pics.

Kinda makes the ‘Patriot Act’ sound like an oxymoron, no?

HKS is quiet, and a pretty nice exhaust. I got a Stromung without a resonator on my 92 and it is kind of loud above 70 mph, but the rest of the time it sounds so good. I did a big review of this exhaust on the forums do a search you should find it easily. I think with a resonator this exhaust would be perfect.

thanks for all the advice..... sounds like the HKS is guaranteed to be the quietness that im looking for and that the stromung might be quiet enough if it had a resonator and that I could also put together a quiet custom exhaust with a resonator and a muffler of my choice

In reality.... I know that i will be replacing the cat with a high flow cat which will make my exhaust louder but most likely not disturbing on the highways, right? (I'm talking 9 hour trips from NJ to NC)

Would it be possible to keep the stock b pipe and install a highflow cat and a muffler, possibly the muffler from the stromung system? is the stock b pipe really that restrictive and detrimental to the stromung exhaust system sound? I like the look of the stromung and would like to have a beefier sound but not a toturous highway sound. Would the resonator on the stock b pipe be enough to keep something like the stromung tame on highways? or would I also have to add a longer resonator?

Basically i'm wondering whether its alright to to just keep the stock b pipe when upgrading the other parts... opinions are more than welcome thanks

for the good of the forum i just want to post the product # for the bolt on replacement random tech high flow cat- RAN 822231 and the reccommended installation is kit is RAN 516033

i got the cat for 175 and the kit for 11 at www.martelbrothers.com
seems like a nice company to be dealing with

the muffler on the courtesy exhaust makes the system noisy, right? not the b pipe?..... if i were to go with a b pipe from courtesy what kinda mufler could i get for it... i know magnaflow is an option but it would most likely be too loud for me. what do you think of this set up? and can you reccomend a muffler and how easy it would be too match an aftermarket muffler to the courtesy. thanks

I am not trying to be a Search Nazi, but why not check the articles on SE-R.net ??

Merlin Johnson did a very comprehensive test on cat-back exhaust, complete with back-pressure measurements between different systems and Shell Black added some more useful information in there. All you want to know about the difference between HKS, Greddy, Borla, Courtesy, etc are all there.

BTW, the Trust exhaust Merlin was talking about, the company later renamed the brand from "Trust" to "Greddy".

Check this (http://www.se-r.net/header_exhaust/index.html)

i think my problem is that i've searched to much and have every post, write up and opinion stuck in my head. The more i find the more confused i get. so it's cool... no search nazi label for you ;)

but i guess i'll kill my questioning till i can sort out twenty web sites ;) but still i guarantee more questions to come.... that is if no one wants to chime in on the ones i've already asked...

looking for high flow, highway drivable, nice sounding, and looking muffler and/or system....
