Deepest Muffler Tone

1994SubaruSVX · #1 10-17-2001, 09:04 AM

I have two Magnaflow mufflers on my SVX and I like the way they sound. But I would be happier if my exhaust note was a little deeper. Heard the stebro at the Rockford meet and it had a wonderful low tone. Anyone know a muffler that could get me close to that sound?? I am not looking for louder, just deeper tone.

Any sense of how Flowmasters might compare in tone to the Magnaflows? I've been thinking about replacing the stock muffler with Flowmasters, but definitely want something with a deeper note.

Chances are Flowmasters would sound like poo on the SVX. I had flowmasters on an old fullsize blazer, and they sonded great, but that was a big cam big block motor. The SVX just dosn have enough cam to sound good thru a flowmaster, and flowmaster really arent that good of a performance muffler. I'd try the dynomax super turbo. It has a really nice flow thru design.... I have thought about putting in a big dynaomax muffler ebhind the cat,, and then a couple of little bullet mufflers near the back end. Not sure if that ones going to take shape tho.... I guess my point is, stay away from flowmasters unless you have a lot of cam.

A couple of use have flowmasters. Ive been told severlal times at meets that they sound less ricy then the magnaflows. I agree. To me the magna's have a tinny sound to them. However you might be able to just enlarge the pipeing after the muffler. A larger diameter can exhaust pipe can make a big difference.

The Stebro tone gets much lower once you lose the center cat. I wouldn't recommend losing all the cats though.

im back to add some input. ok my exhuast has a decent low tone but as i hit over 3 rpmish it goes away then comes back at 1 1/2 to 2 1/2ish. my system is dynomax and thrush. but i heard this one guys car with a really low tone and sounded awsome he had canister mufflers and i forgot the brand but they sounded good. and to believe what it was on was strange. a tiberan hyndai (spelling whoa). so my next exhuast project will be to replace the mufflers and the glass packs with canister mufflers. 4 to be exact to get rid of the packs and drop the sound. good idea bad idea input would be great. i do want to avoid the ricer sound like a motorcycle.

just remove the muffler and have you friend up the street bend up a "tail pipe" i think it sounds great.

Thanks for the comments. I'll keep that in mind, if and when I get around to working over the exhaust system. Thanks again.

I have done a dynomax super turbo and a flowmaster 80 and the flowmaster is definitely deeper. With the flowaster and no glasspack the exhaust rumbled like a v-8 at idle but it was way too loud when accelerating. The dynomax sounded too high pitched and made the svx sound like a weedeater. The flowmaster with a glasspack is the way to go for a deeper sound that isn't too loud to drive.

Matt, is that what you have on your car now?

Matt: what size are you running? I actually had a picture in my head of my old twin three inchers, and the little 3.3 trying to keep enuf air in em to sound decent.

Well, I don't think I'm the Matt everybody's talking to, but I'm gonna butt in. I've got the KC exhaust on my SVX, and while the exhaust is a little bit of a high tone, combined with the intake I think it makes a great throaty call. One thing I would say, just out of gut instinct (no fact or theory behind it), that the resonated tips are to "blame" for the sound it makes. I think tips without the "cheese grater" inside would greatly change the sound. Maybe not, though. Somebody correct me if I'm wrong.

sounds like i may just need to slip a glass pack or two on my exhaust and check out out it sounds.

If you have the KC exhaust and it's exactly the way it was when you bought it, then you have resonated tips. If look into them you can see the little protrusions or slits that "resonate." That was one of KC's main claims on their web-site, they said it was better than a resonator (full resonator is more restrictive). Wait....writing this and remember you don't have KC exhaust....never mind

Right now I have the factory exhaust manifold down to right behind the o2 sensors, then 2 - 2" pipes join together into a single 2.5" pipe right where the main cat would have been. Then a 14" long glasspack where the resonator was, then 2.5" pipe back to a flowmaster 80 single in dual out 2.5" camaro muffler where the stock muffler would have been with tailpipes exiting at the stock location. I wanted to do duals all the way back but flowmaster does not make a muffler short enough to fit 2 in the factory location.
I ran the car with open headers - no muffler- for about 10 minutes. It was evil. I loved it but in about 30 more seconds I would have been deaf. I ran it with both the dynomax and flowmaster and no glasspack for a while (not at the same time). Very loud even when just putting around with either muffler but with the flowmaster it was a good loud in a v-8 kind of way. With the dynomax it sounded like a weedeater from hell. Way too loud to take a long trip in. Right now it is still loud but not tiring on long trips. It stays pretty mellow when just cruising around but it does get loud when its revved up.
