Lets have a muffler thread

[8v-of-fury]

best piece of advise i can give you, is get rid of the fart can.. they are basically only good for honda, acura, and nissan gassers. lol..

I think it suits his particular car well k3vo. Its just a straight through muffler, probably sounds awesome. LoL.

[grape ice cream]

so i was planning on making my own exhaust system
just wanted to know what kind of metal most people use when making a 2.5in downpipe and to the back?

My significant other got it for me, as a birthday surprise, took it to the cholo exhaust/tire shop, had the whole exhaust system done for me, this is what they put on there and I didn't know until I started the car..

They tried. That's what counts. I would love to hear a video of how it sounds though, for isht and giggles.

ever seen a Moroso spiral flow muffler? they look like they would work AWESOME on our small diesels..

Randomly, I just used 2 of them, and a Dodge pickup 3" tailpipe...I used OE hangars, and junk I had laying around, probably in it $30 and some frustration



I tried open DP, and the fumes  from the tailpipe  made my eyes bleed.
Went 3" with one Moroso behind the axle, and it was still pretty loud.
Hacked in the second one just before the axle,and it is quite nice, tolerable loud... except on the freeway high throttle around 2500 drones painfully. I wonder if a muffled tip might help, but I like my slash cut.  Fumes are ejected nicely out of the slipstream.

Still, just a massive 24 inch (at least) glasspack for $60 (yes expensive) made my 2.5 straight pipe still straight but way way quieter. The rubbing exhaust on the car body is way louder.

i saw these pics the other day, i was wondering what you used. kinda looked like moroso's.. there the same muffler we run on our sand rail.. sound nice on there, bet they sound nice on your Volvo also!

So by what i have read on this subject it seems that straight exhaust isn't too bad. I am going to remove the muffler and resonator and run the factory size exhaust. Mainly it is going to save me some money and I thought perhaps gain a little on MPG. I just want to make sure that it's not going to be crazy loud at highway speeds. (70mph or so). I'm getting it done on friday, if i hate it I can take it back and get a muffler installed. Thanks.

not gonna get any more mpg unless you open up the exhaust system a bit. that restricted 1.5" exhaust pipe is just too tiny to be any good..

its going to drone at 70mph with no muffler at all..

[trent77]

So my exhaust is 2" already. I am back and forth on going straight pipe. I am going in for exhaust later this morning. The pipe is pretty bad at the back of the resonator so i would be starting fresh ahead of that. Not sure which turbo I have, my engine is an AAZ out of a 1994 a3 Jetta, so if my turbo makes a difference on sound maybe I have one that will be quieter.....hopefully.

[R.O.R-2.0]

VNTs are the quiet turbos..

conventional turbos are a bit louder..

[trent77]

well the exhaust is on and it is really no louder than when it had a resonator and muffler. even at 80mph. also under full acceleration not loud. I installed 2" all the way. Very happy with it! By the way, it really sounds cool when you fire it up and you hear the turbo spool and whine at idle.

mine whistles at idle, and really starts screaming around 2500 rpms..

i wish i had a waste gate tho.. i love wastegate rap..

[blackbird82]

huh, i put a straight pipe on my 94 AAZ jetta. IT has a T2 turbo, and no idle whistle or cool whooshing sound under acceleration

now my cousin has a 97 AAZ with the same exhaust, but he has the smaller turbo, the tiny one. K03 I believe.
IT has a cool whistle and whine

WHen my waste gate opens its a cool sound though, reminds me of a four barrell

[vanbcguy]

I notice a lot more turbo whistle / woosh from my intake than my exhaust.  You CAN year it through the exhaust, but the bulk of the turbo sound with Jezzie is from under the hood.  Significant difference between the stock airbox and a cone filter.
