Hey everyone, I had a few questions, so I'm hoping you can help me out. I just put in a test pipe a few days ago and I like how throaty it sounds, but here are a few things I would like...

1. I want to hear the exhaust in the car more. It seems like with the test pipe, it got quieter in the car and less "boomy", but the exhaust seems decently loud outside the car. Would 2.5" straight pipe from the test pipe back to the flowmaster 40 series be too loud inside or outside the car? I define "too loud" inside as not being able to hear other people in the car or insane drone and loud outside the car is normal driving is obnoxious.

2. I know everyone wants their Maxima to sound like a Z/G35, some exhaust combinations come close, but is there any that sound really close while only touching pieces from the cat back? The stock cat got destroyed in the process of putting in the test pipe (read: cut through because of rusted to **** bolts!) so I would have to use the test pipe. Would a Magnaflow make it sound better? Leave the resonator? Delete the res and go 2.5"?? I just want opinions to see what people think. And I would like to know how 2.5" piping from a test pipe back is going to sound and how loud it would be.

Thanks again for all the help. Help me with this and I will post a clip for you all when I change my setup around

 

Run open Exhaust manifolds only (dual exhaust!!!!!!) That oughta be loud enough.

You're a genius...

Anyway, can I get a real answer from someone please?

 

my greddy catback sounds pretty close to a g35, just a bit deeper

 

Cool, but I was looking for how I can modify my current setup that I already have instead of buying something completely new.

I wanna know how 2.5" piping from a test pipe back to a flowmaster 40 series would sound. I don't know if it would be too loud, but I would like someone's opinion on it first before I just go and do it myself. I want to see what people's thoughts on loudness and tone are.

 

one of the guys on here that is local to Toronto, had test pipe no resonator and it didn't sound any louder then my car with headers. That surprised me as I thought no cat no res would be super loud.

He's got headers now and he needs to put the cat and resonator back in because it is way too loud.

Thanks for the info, knight! So is there a big difference by taking the res out? Like alot louder, or just a little louder? Do you get that popping noise when you decel and shift? Know what I mean? I love when a car does that haha

 

I do but I have headers, I'm running a resonator because I don't like it too loud. There are a few local guys who have taken the res off their autos and the car isn't much louder with stock manifolds. Even at WOT it isn't as loud as you would expect.

 

Ok, so it won't drone in the car? And it won't be obnoxious outside of the car with a test pipe, 2.5" in piping to the flowmaster 40?

 

Ok! My first response was just for laughs, OK! If you like it sorta of loud just replace the rear muffler with an aftermarket $20 Ebay muffler and fix the the crimped down pipe behind the resonator and you wishes shall come true!!!

 

I'm almost certain it will be raspy sounding because that test pipe already causes a bit of that and it would amplified by not having a resonator.

 

I'm sure an eBay muffler would sound like ****. Unless knight_yyz tells me that the drone in the cabin is bad without the res and a 2.5" pipe, I'm gonna do that.

The only thing I would change my FlowMaster out for would be a Magnaflow if it would sound better. I hear that it gives a more "exotic" tone, is that true?

 

Raspy as in throaty or raspy as bees-in-a-can-honda-farting-exhaust?

 

Bees-in-a-can metallic raspy.

If you want a throaty, smooth, and deep tone, keep your resonators or maybe get smaller resonators, as well as some headers. Those, along with the straight through muffler, will probably do it.

 

I can tell you from experience that a magnaflow or any "glasspack" straight-through muffler is going to sound better than a flowmaster 40 series. That flowmaster will let sooo much rasp through.

This is mine with headers, stock cat, stock resonator, 40 series flow. It lasted about 2 weeks lol...

Aww, damn, really? I was hoping it would be like the video knight posted. I thought that sounded pretty good.

I just want something a little bit louder in the car, and if possible get that popping noise I love that sound? Would a better route to go be getting a glasspack resonator or something since I want that G35-ish sound?

 

Maybe I'm just more picky about the exhaust tone, I like "clean" sounding with nothing that I think is raspy or bees in the a can.

Here's my previous set up, which except for volume, was exactly what I wanted:



Headers, stock cat, resonated b-pipe, straight through muffler (Megan Racing)

 

You're going to get the most popping out of a straight 2.5 or 3" exhaust with a perforated resonator (magnaflow) and a straight-through muffler (magnaflow also good choice here). I don't know if I'd try going without a res, but without headers it may not be too loud.

 

That doesn't sound too bad to me from the outside, guess the inside is worse? I feel the same with my car, sounds great on the outside but inside the cabin could be a little quieter

 

So something like this? Test pipe > 2.5" piping > Magnaflow Resonator > 2.5" Piping > Magnaflow Muffler.

 

Here's mine from the outside, cattman gen3 headers, cattman fast cat, cattman catback

 

Yeah that's usually a good combo for sound. IF you plan to get headers, make it a 26" resonator, and it will be pretty quiet until you get them. Otherwise go with a small res.

 

I think it sounds good too, the problem is I think headers change the tone alot and I don't have headers done. So I'm just trying to figure out how to get the sound I want with most of the setup I have now.

 

You won't get that "exotic" tone without the equal length headers/Ypipe. It's going to be more throaty and poppy with your stock stuff.

SurraTT (u can PM him here) has stock headers/Ypipe and a flowmaster 40 series muffler. It sounds great... Lives right down the road from me.

 

Small res as in what? Sorry, I'm as much of a n00b as you can get with this stuff I know there is a magnaflow on the forums here for $40 bucks. I'll pick that up, but I just wanna know what would be a good size resonator because I won't be going headers or anything else to the exhaust for a while. I have to budget for coilovers

 

you can buy a resonator anywhere from 10 - 28 " long. so small would be 10"

 

Yeah, I talked to him already. That's how I ended up getting the 40 series in the first place

So than to finish this discussion, that little diagram I posted before should give me a nice throaty tone with some poppage, right? I just need to know what size res I should get.

 

If you want it to be pretty loud, you could get away with a tiny one... 4x9" or a 5x10" maybe, any of the smaller ones.

 

I know everyone is different and has a different idea of what loud is, but I want something that is fairly loud but won't be booming or droning too bad in the car. Will the magnaflow res do that? Best place to look for one? I didn't see any for sale here.

 

Any exhaust that sounds fairly loud outside WILL drone at 2000-2500 rpms. I guess our cabins just resonate there, not much you can do about it. The magnaflow is going to sound smoother, the flowmaster will sound more throaty (they call it a pontiac sound =P)

 

Well than, I guess I will do this... I will find a magnaflow res and get the 2.5" piping done and see how I like it with the flowmaster. If I hate it, I'll grab the magnaflow and and go from there to see what that sounds like.

Only thing I need to figure out now is where is the best place to buy one from and what size I need. Like I said, fairly loud, but not insanely loud.

 

Hmm... 14", 18" or 22"? Obviously 2.5" ID/OD but hottexhaust.com has some really good prices on there. Any recommendations??

Also, thanks to knight_yyz, sparks03max, and Puppetmaster for all the help so far. You guys are reallyy helping me out!

 

I can't remember how big the stock resonator is. My current one is 21 I think.

OD will probably be 4" ID stock is 2.25 length is a guess. Shorter equals louder.

 

Ok, thanks. But how much louder is a 14" gonna be than an 18"? Compared to a 22"?? I know some of this is guess work, but I know some of you guys have been around long enough to know alot more about this stuff.

I'm just guessing that if the stock res is 21", an 18" will be a little louder but a 14" will be alot louder??

 

I know the guy in the original video I sent with the test pipe and no res ut headers on his car and now it sounds like a sherman tank. He put a 10" resonator with a larger chamber (6") and it didn't do a darn thing to quiet the car down. If you are staying stock I would go with the shortest one.

 

sherman tank. ok, so a 14" resonator should sound pretty good with my current setup and 2.5" piping all the way?

 

I wanna hear from all 3 of you guys. I'll order it tonight if I get a consensus from you guys!

 

My car is the one that knight_yyz originally posted. With my Vibrant part # 1148 muffler, unresonated b-pipe and test pipe I gotta say it wasn't too bad at all. Cruising around town it had a low, deep sound and a lot of people complimented me on it.

Just the other day I had Cattman headers installed along with a Fastcat, still keeping my unresonated b-pipe and straight through Vibrant 1148 muffler and let me tell you when we fired up my car for the first time it sounded like my tech's full blown race car!! It was exactly like a tank lol. The very next morning I had a small Vibrant resonated welded into my b-pipe, about 10" long. That didn't do jack to quiet my car down.

I am now in search of a resonator or muffler that is packed with steel wool instead of fiberglass like most are.

Here is what my car currently sounds like: I don't think it's terrible...just VERY loud and just a tad raspy. Any tips from the big org gurus to quiet it down would be appreciated(by my neighbors LOL).

Throw the largest mangaflow or other non baffled resonator you can in the midpipe and you'll be good to go.
