New muffler too loud (1 Viewer)

[CruisingNaturalist]

I have an 87 HJ60 2H

When I had a muffler installed at a muffler and rad shop, I was given a choice for a 45 dollar flow through? muffler (looks like a round cylinder) which I was told would be a little louder, and a regular muffler at 60 dollars.

I thought, a little louder, well ok and I can save 15 bucks!

Well, yahoo.....but now I can't hear the quiet purring of my engine because of the annoying hum coming from the back-mind youthe rear hatch rubber is gone.

It's so much louder and I can't stand it....thinking of putting on another new muffler.

I love to hear the engine and want to hear if there are any changes in the sound for maintenance reasons.

Any thoughts? Should I have spent 300 dollars which I was quoted at Midas?

Thanks in advance
Tim

Make a CD of a ferrari engine purring and play it will you are driving.
Lesson of the the day cut corners on cost and you will regret it tomorrow.

So the muffler dumps out the back? if you make the exhuast tip so it is bent down slightly it will help a little with noise...

Honestly I hear you on the noise, but on the other hand it helps keep exhaust temps down with a flow through muffler! and if you don't have a gauge, i'd bet you run it HOT!!!

Thanks for the comments.

I put this muffler on because I don't know what the differences are, not because it was cheaper.

Still, no one has told me what I should expect to pay for a good muffler. Should I go to toyota, back to Midas, or order something through an automotive supplier?

What is going to give me a quite ride?

Thanks Tim

a good system sets me back between $450 and $750, this includes the aluminized exhaust, steel muffler and steel resonator.
i like my systems tucked up out of the way and i want them to last.

so
you got what you paid for...you could also go with a resonator...

Thanks Crushers.

Try putting in some type of dynomat,carpet,something to cancel out the vibrations until you can afford a better system.2 cents Mike

Put in a turbo. It's a "muffler" that actually gives you a performance improvement!!

I don't run a muffler on any of my trucks since installing the turbo and I do not find it objectionable at all (it is a diesel after all).

 

[CruisingNaturalist]

Thanks for the recommendations.

Still don't know what a good system is. Is it something that resembles the factory system?

Would a purist go for a factory system just to have the original sound from his/her cruiser?

Are all resonators and mufflers created equal? What is the difference?

Can I tell if it is a good system by the price or by how long the warrenty is? Like 2 years =bad and 5 years = good?

Ever since I put this thing on, my engine sounds "sick" to me. It just doesn't sound right and.......is it possible that the new system could be decreasing my fuel mileage?

thanks,Tim

The "best" system is one with the least back pressure that doesn't get you in trouble with the law! If it can give you a performance enhancement, like a turbocharger" that's a bonus.

Warrantees on exhaust is a game played by the exhaust shops who all know that most folks do not keep a vehicle long term. I had the OEM exhaust in my BJ60 (which carries a lifetime warrantee from Toyota) until I got the turbocharger. Is/was it "the best"? Not necessarily. I think my current system with the turbo is better because of the performance enhancements. If I didn't have a turbo I'd probably still have the OEM exhaust system.

where are you located?

factory is nice but not worth the dough, once we know where you are maybe we can recommend a decent shop...

mufflers are not created equal, that is like assuming all trucks are created equal...

 

[CruisingNaturalist]

Thanks again

I'm in North Bay

Is Midas half decent? I was scared away from them when I couldn't get them to agree that mine wasn't an FJ! Thats the only thing coming up on their computer.

i have a guy down here outside of Owen Sound that is an artist with a bender. he follows instructions and the last system he made for me was beautiful, quiet, tucked up out of the way.

do the drive down this friday to the wheeling meet in Parry Sound then carry on to this guys place. he is NOT cheap but the exhaust will last as long as you own the truck...literally.

I've had decent stuff from Midas and I've had stuff that looks like a kindergartener did. It's a crap shoot. If you go there you need to be watching them the WHOLE TIME. They did the system in my BJ60 and I was there watching and it seems to have held up well. They did the FJ55/3B conversion a year later and I was not there and it was terrible!

 

[crushers]

each shop is individually owned, i used minute muffler in Calgary. the one shop did s*** work with no warranty (warranty expressed but not backed), the other did beautiful work and the did dozens of my exhausts.

ask around at the classic car shows, they are fussy and want nothing but the best BUT expect to pay top dollar.

Here is my latest exhaust project on my '42. I located the mufffler here for a couple of reasons:

1) I don't have a bender and I wanted to have my exchaust 'serviceable' by readily available bent pipe parts. These ones came from Canadian Tire. Total cost of part <$100 including the Walker muffler (which actually came from Lordco). The muffler is tucked right up so it almost clears the frame rails (I bashed my other muffler on a wheeling trip when it was located in the back)
2) I've been thinking about installing an auxillary fuel tank and this would free up the room behind the rear axle
3) I checked the BC Motor Vehicle Act and technically, this is legal, because it has a muffler and exits out of the vehicle. It is a little close to the door, so it may present a burn hazard to someone entering/leaving, but arguably, it doesn't. It really isn't that much louder, hardly noticeable actually.

Questions:

1) Are the EGT's going to be too hot for the muffler being this close?
2) Do I have too little 'back pressure' with this setup?
3) Any other comments (love to hear them!)

I'm just a do-it-yourselfer at heart. I have no qualms about putting in a proper exhaust system; I just like to try it the easy/fun way first!

Hey Rob,
The problem I see with your set up is the lack of exhaust suspension. Unless you have a flex pipe coming from the down pipe to the first bend. I suspect you run the risk of cracking the exhaust manifold. Instead of those straps (which won't hold up long due to vibration), you should put in some proper exhaust hangers. This way when the 3B is vibrating it's transfered all the way down the exhaust + keeps vibration from transferring though the frame/body.
Just my .02.

I like these:

Thanks Phil,

I wondered about that, the hangers provide some give, but not enough as you suspect. Should I put in a flex pipe as well, right where my exahust comes off the manifold?

Where did you get your hanger? I didn't see that style at CT.

 

[cruiser_guy]

Rob, there is no such thing as "not enough back pressure", it would be even better if you hooked up a vacuum and sucked out the gasses (well almost)! Watch the cars at Mission Raceways one day and see how much backpressure they are trying to introduce to the system.

On the exhaust expansion thing, the system on both the '60 and the '55 expand easily a full inch or more from cold to hot! If you do not allow for that it WILL break somewhere, usually where it's toughest to fix!

I wouldn't worry about the flex pipe, if the motor and exhaust are bolted together as one, then all you need to do is make sure the exhaust flexes with motor. No rigid strapping/bolting to body or frame.
Lordco, ask for a good quality universal exhaust hanger, the one I posted is SS, I use regular old steel ones. I usually keep one or two in the trail parts bag as well.
