A guy at work used to work for a shop that did exhaust work. He told me they used to put mufflers intended for a Camaro in 350Z all the time.

Has any one just put on a muffler and how did it sound afterwards?

I just can't see spending $800+ for a cat back for such a tiny gain.

Or would high flow cats be a better alternative for extra noise?? I love the F1 type sound the car has now

 

A few people on here have put flowmasters made for a Z28 on a g35 and it's turned out pretty good.

 

Is this 800+ for a muffler only??? I designed my own costum exhaust for 180 dollars. For $800 u can get costum true dual exhaust with chrome muffler, chrome x-pipe and glasspacks.

 

fbody mufflers are what you are talking about...and catback systems that are designed for our cars do more than just sound unlike just adding in a muffler

 

Camaro mufflers are not good matches for the car -

1 - you'll get drone
2 - one side will be louder than the other - the drivers side

The inlet for the drivers side makes a fairly sharp uturn and goes right out again to the tip. The other goes all the way across and out the right side.

The main reason they were used is because in the beginning nothing else was available, and they are still used out of bad habit.

Don't do it...you'll waste your money and continue to dump more into exhaust needlessly.

please dont........either get a full new exhaust system or dont get anything

 

O.K you all got me convinced. All I am looking for is somemore noise from the rear. I don't have the funds for a catback. So, in the interest of the environment, will high flow cats give me the volume, aka decibels, I seek. Again I seriously like the stock tone, it just needs to be a bit louder.

 

From Stillen's web site: (I added the bold part.) $949.00

STILLEN Single Path Exhaust System adds performance to your G35 Coupe (7 horsepower!) at an awesome price! Made of stainless steel, this system features dual dips from muffler, is mandrel bent, and utilizes 3" tubing allowing for smooth flow of gasses through the pipe. This produces a firm noticeable performance increase.

This exhaust system includes the STILLEN Y-Pipe (Part #504252) or is available as a stand alone unit without the Y-Pipe (See Part #504271)

That's $135.00 per horsepower!!! WHAT A DEAL!!!


Fujitsubo taken from Gruppe-S.com : (again I added the bold part) $849.00

Sound levels are increased 11 decibals at idle and 9 decibals at redline. Horsepower gains are rated at 8-10whp and there is a 7lbs weight savings over the factory system.

That's $85.00 per horsepower. Better but still a bit pricey!

Greddy Hyper Titanium: $1499.00

Exhaust consist of a carbon fiber wrapped muffler shell, titanium tip, and polished SUS304 stainless steel piping. 6-10whp gain

$149.00 per horsepower


I could go on. All I am looking for is a little more noise.

I understand that these cars are highly tuned from the factory and any gains from bolt on parts will be small. I just cannot fathom anyone spending $1500.00 for maybe 10 hp. Hell NOS is a little over $1000 and that get's you a minimum of 100hp.

I know an F body muffler is not "for my car" but come on, will I really be able to tell that the right pipe is louder than the left pipe?

O.K so a Camaro muffler is not a good choice. Are high flow cats a better option for more noise and maybe a little more than 10hp???

A straight definative answer would be nice, thanks and TTFN

 

If your looking for performance in exhaust you have to start from the back first - you can't start from the front back - it defeats the purpose to open up the font of the exhaust and leave the back restrictive.

Our test pipes put out about 10 HP and the same in TQ on a stock 350Z - http://www.fastintentions.com

You'll get some nice improvement in sound, no rasp and the basic improvement of a catback as well. You will also have to deal with CEL issues, but that is dealt with non-foulers, and then the smog-test issues. They are designed for off-road use only.

These are the contentions you have to look at and why catback systems that are worth anything are out there.

Out catback will give you a great tone, no drove and no smog issue or cell problems, but at more cost as well.

O.k, maybe I'm stupid and I'm stuck in domestic V-8 thinking but cats were always the first modification done. I've had 3 5.0 Mustangs and currently have an '86 Buick Grand National and the first thing is to put on a test pipe.

The searches I have done here seem to back this up. Rick, I am in no way doubting you or your expertise as I am new to this import scene.

I love the way my car sounds now. I would just like to turn up the volume a bit but keep the stock tone. State inspection test and CEL are no problem for me. I just figure if a $400 test pipe will give me the sound plus the same gain as a $800-$1500.00 cat back it's a no brainer. Maybe a cat back will come later but now I have to recoup the purchase price of this car.

Sorry to drone on but like I said I'm new to the import thing and I have a lot to learn.

 

it seems you prefer sound over performance. i suggest you get resonated test pipes as this will reduce most of the raspiness that you would get with non-resonated test pipes.

test pipes will give you more performance gain than HFCs too.

usually, more power = more sound

 

i'm going to run open header.s....that should give me lots of power ^_^

 

Having extensive experience with Camaro's (raced a 10 sec 2000 SS), I would not agree with this. I've never experience one side louder than the other, and neither have I ever experienced drone from the GM setups. Although I do agree that it's not worth going this route, because they're many catbacks to choose from. But buyers beware, many of the catbacks will produce more drone than any stock Camaro muffler. Think of it this way. The stock Camaro mufflers were meant to be quiet on a much bigger and more powerful motor.......

As for Flowmasters, they use a baffle design that are one of the most restrictive choices out there. They sound good, but actually flowed less than the stock GM muffler mentioned above when our F-body club did flow tests....

Best advice is to listen to the catback you're interested in before you buy it. There are more than one catback for these cars currently on the market that have very ricey sounds to them, as well as cabin drone.

 

greddy sp2 is an axle back. Just a muffler. Sounds pretty good if you want a cheap alternative. I am selling mine for $300.00 local or shipping just let me know your zip if you want a quote.

Fast intentions does have a good sounding exhaust. I just had their resin. test pipes installed and sound awsome and with very little rasp. I mean very little. If you run your car normal the sound is the same but at wot the thing pushes a bit harder and the sound is exotic. +1 for the people at F.I. Tony was one of the best and informative installers I have ever met.

 

A lot of stupid people do stupid things! If your not
going to upgrade your G why even think about
installing a Camero muffler? I've seen some really
good systems on this site used for very little money.
If your not going to upgrade with quality items then
leave your G alone!
