I am waiting for my arrival of my racing beat header. However, I did not buy a presilencer or a powerpulse muffler as I do not want to spend that much money. (I live in Canada just the header, gasket and alt. pully is going to end up costing around $500 after taxes + shipping)

Does someone have any good muffler suggestions (besides Racingbeat) that are not fiberglassed, and will not be too loud? I was thinking that the Hooker aero chamber looks well constructed. What do you guys think?

(I know the Rotary exhaust is hot and etc. I do not mind if the muffler only lasts a few years.)

Thanks

 

Well, I dont' know about mufflers other than RB...
But you know you have to fashion a connecting pipe from the RB headers to your muffler, right? The RB headers are too long and replace like 1.5 (pre-)cats...

 

You might as well and ante up right now for the presilencer. Your car is going to be WAY loud with out it. I use the Monza pacesetter muffler, so far I have a year out of it and it still is working.
By the way, why the alt pulley? Old one toast? If you are taking the air pump off, you don't have to have the double pulley right away, although you may get some screaching from your current belt.

I have a Pacesetter Header which replaced all the cats, so i had to fit on in by the axle just for emissions and i also have a Vibrant Muffler which is toast... probably about a year old, but anyways, the car isn't that loud, yes it is more than most but nothing you can't handle and the idle just sounds soo good

 

I have heard horrible things about pacesetter headers. Are that true or are these actually descent quality.

I know I have to make a connecting pipe. Also, I thought I might as well by the dual sheave alt. pully and block off plate now as my friend and I will be splitting the shipping. This way I will not have to pay for shipping twice. Is it really that loud? Right now I have gutted cats and I have a big hole in front of my muffler and I do not think it is too loud. Also, I ran the car just off the stock manifold, and while it was loud it was no where near as loud as my Jetta Gli when it was running off its stock manifold (maybe because the compresion is 10:1 I don't know) Anyways, any suggestions on mufflers (other than Racing Beat)?

What do you guys think of the hooker aero chamber? It is made with stainless steel? And it does not look like it would be too loud. (then again I do not know much about mufflers)

i have the bonex cat and 2.25 inch custum pipe hook with dinamax muffler. i have the muffler for a year right now and it still ok and does't sound too loud.

 

i bought pace setter header for my '83 GSL and returned it. it wasn't a stright bolt on. the bolts where off about 3-8mm. and the monzda muffler sounds like crap, haven't even had it a year, and there is rust on it already, paint totally burned off, etc.... if you want your car to sound like a weed wacker on crack then get the monzda muffler and hope you have better luck with it then i did. spend the extra money to get your 7 the best. just my 2 cents

 

I am not going to put a pacesetter muffler on my car. My friend has them on his second gen and they are too loud. They are practically a straight through design. Why does everyone keep on talking about pacesetter? I want to know about diff mufflers.

eddierotary: what kind of dynomax do you have? It is not glass packed is it?

 

Edelbrock makes a stainless steel muffler with packing that can survive 1800 deg F. It's also got a lifetime warranty on the same car, so it's basically also the last muffler you'll have to buy. Just measure the spot where you plan on installing it and go through the catalog to find one that will fit. Keep your receipt to copy later on. I bought mine 5 years ago and had to replace it last year. I had no problems with Jeg's or Edelbrock about the free replacement even though an obvious huge dent was on the front plate where it got whacked on a particularly bad pothole I ran over at speed. The tone is deep and reminds you of a non-turbo Lotus. No high metallic sounds or weed-wacker nonsense at all.

 

I know a guy with header and just a muffler and it is too loud for my taste. I saw one at an autocross with header and a supertrapp and it was too loud. save your money and get a cat or presilencers. than what muffler will not matter so much.

Just my $.02

 

I've said it before and I'll say it again. Mufflers and presilencers work in conjunction! I had the RB short primary setup for awhile and ANYTHING BUT the PrimaFlow or Mazda muffler was WAY TOO LOUD! I went through sooo many muffler while trying to make it sound like it did with the primaflow. I finally gave up and got another primaflow... the difference was amazing .

 

I agree with RXcetera. You have to have the presilencer with the header, or have a cat. The cat is what does the majority of muffling the sound on a stock exhaust system. In fact right now on my second gen, I dont' have mufflers at all. It is actually quieter than my first gen with the RB, presilencer and monza muffler.
just my opinion,

I ran the stock muffler for a few months until it finally broke up internally and basically fell off... wan't very loud but also wasn't very fast either.

Don't believe them when they say a cheap boinger muffler will only last 6 months to a year tops. I tried one, put it on at 5pm on a Thursday, sounded like a demented Honda or a dying bagpipe (bad), was NOT quiet, and at about 9:30pm on Friday the muffler split wide open at the seam. HOURS or BLOCKS DRIVEN as Mazdatrix puts it is an accurate description of the life of a cheap muffler!

If you do get a cheap muffler don't go for big tips, get the largest and heaviest one you can fit under the car, and get one that is at least welded in construction instead of merely crimped over. On reflection, that muffler might've lasted longer if I seam-welded it and made support straps to go around it so it wouldn't balloon... but that's an awful lot of work for a $15 muffler.

 

My pacesetter headers have not been bad at all. The only thing was the first time i started it up it burned off the paint but that's is no problem since it will happen with all of them.... About not lining up well i don't know because before having put on the header i made a custom exhaust so either way it wouldn't line up since it wasn't in exactly the factory places... I have really had nothing to complain about the headers

 

That's funny, I had to work at mine for quite a long time just for it to fit over the studs on the engine. This was working with the engine on a stand, so trying to do it with the engine in the car would be even more difficult. (drap in header - does it fit? no - where is it hanging up? pull header out, grind holes some more, drop it in again, etc.) Then I had to spend another 30-45 minutes grinding out all the flash in the collector, unless you have a 1.5" exhaust on your car i suggest that you do the same, because that's how restricted mine was where the two pipes merged. Then I had to spend another couple of hours grinding and cutting and swearing on the exit flange, trying to get it to fit over the studs on my heat exchanger.

The funny part is, the Pacesetter appears *designed* to fit a '79-80 model. The header is the exact length and angle as the factory manifold and downpipe, so it SHOULD have been a simple bolt-in.

 

I wanna buy a cherry bomb for the fun of it. Make some people go deaf.

 

I run a pacesetter header thats ceramic coated,Dynomax turbo tubes and a stainless case FlowMaster muffler.They have been on the car for about 2 years with no problem.Nice and growley down low with out being too loud when I stand on it.We have a sound limit of 95 db.at the track I run and never had a prob. meeting it,or had a cop look sideways at me.

 

What are these "turbo tubes"?

I assume you have two of them? Do you have them parallel (long primary system) or inline? Which specific muffler did you use? (meaning 2-chamber/3-chamber/what size inlet?)

Curious, 'cos I need a quiet exhaust system post-header.

 

Turbo tubes are a chambered resonator,anyone that deals in dynomax stuff will know what they are ,long primary system with turbo tube on each pipe.3 chamber flow master 3 inch inlet outlet collected before inlet with a small meg from collector to muff.
