Turbo Muffler

[Dddaviso7]

What are you Turbo guys running as a Muffler?

I don't want a "Ricer/Tuner/Weed Whacker" sound. I heard a chambered muffler is bad for the turbo.... Then again, You can't believe everything you hear. I just want some real information, It'll be appreciated! Thanks

go with a tsudo muffler or something along those lines. make sure to use a resonator with the muffler, it will sound like crap without it.

I was looking at the Tsudo products, They look like those mufflers that are on Civic's and other Import Tuners.... I don't want that loud 4cyl sound.

So a straight through muffler and resonator are the 2 main items I should look into?

a tsudo exhaust is the kind on dsms evos, sti's talons, eclipses, they sound good with resonators. with a turbo you want minimum backpressure to help spool faster and give quicker boost response, so a straight through muffler is best, but this will not sound very good, so a resonator helps give you a nice grumble but not restrict the air flow. just start youtubing untill you find one you like. and for piping i would go for 2.5 for good low end and top end power. hope this helps, dave

personally id go with a magnaflow straight through muffler. but thats my opinion

Bingo. You want to deaden some of the sound waves, but not hinder exhaust flow. The turbo will kill alot of the sound but a bit more muffler will make it sound okay. I used a 3" straight through no name (not cherry bomb style) on my 96 turbo ranger. It worked very well. Anything that adds backpressure will hinder the spooling of the turbo.
The 240sx (see sig) uses a big old canister on a 3" exhaust with a resonator in the mid pipe. You guys would call it rice... but I know better. I'm a big voice in the function over form ideaology and I'd rather have none-knowers bitch about the size of my exhaust, when all that matters to me is spooling faster without being too loud.

I'd definately recommend 3" exhaust. As was said before, anything in the exhaust after the turbo hurts it's ability to spool. You want as little restriction as possible. 3" is not overkill for a turbo motor. Besides that, the 2.3T is easily capable of 300 horsepower. Any V8 pushing 300 horsepower has at least a single 3" exhaust. So you're looking at 3" simply based on power levels....

i liked my fart cans and when i build my turbo 3.3 im going to put a 3" exhaust all the way back then split it at the end and install dual 2 1/2 or 3'' fart cans straight out under the rollpan where the license plate goes.

hehe, your truck.

If you dont want a "rice" sound, your only option is a chamber muffler.

Frankly, if your after a good exhaust note, it may be worth a couple of HP to get the sound you like. Contrary to popular belief, straight through mufflers have restriction as well, anything that limits the sound also has an effect on flow, and that includes perforated metal in straight through mufflers.

Personally, when I get my 2.3T fairmont going, im going to run a 3" thrush welded muffler for driving and Put a cutout with a plate at the bottom of the 4" downpipe for when im out at the track. That way I get the best of both worlds.

On 2.3T's, it really helps if you split the exhaust and run 2 mufflers and duals. Takes the tractor sound out of it and actually kind of sounds V8ish at idle.

yes but creating more backpressure kills the idea of a turbo. you want the least restrition possible so the turbo will spool faster and boost quicker. and with a turbo, it will automatically sound better than a n/a 4 banger, because you are pushing me air through the exhaust. that is why i said do a tsudu muffler with resonators. thats what my buddies 90 eagle talon tsi has and it sounds very nice. or even a manaflow with resonators. see the resonators help to cancel out the annoying sound wave while still performing at the best. and your right, straight thru mufflers have some restriction to them, but do something for me. take any off the shelf turbo muffler, flowmaster, thrush cherry bomb, ect, and with your mouth, blow throw them, then blow through a straight muffler, which one is easier to blow through? then think of your turbo blowing through it. my point exactly.

yes fart cans make a restriction that slight amount of backpressure helps n/a motors. yes its my trk and yes thats what i want so thats what ill do. ive had a flowmaster b4 and it helps but i want the flow of a straight thru so thats what ill use, and the fact that im doubling them up actually helps quiet it down some. ive had one and it was loud i put two sidebyside and it helped knock it down. what kind of convertor would you guys use? and what do you guys think of flowmaster 10 series? it would break down the noise (somewhat) but still have high flow characteristics as well. a friend of mine had dual turbo mufflers on his 3000gt twin turbo, blew them in half at 15 psi. they were flowtech raptors (not sure if that has anything to do w/ it) but i wont be putting that style muffler on my boosted engine.

Where did you get the idea that backpressure was a good thing?

Are you a moron??

There is far more backpressure on the engine before the turbo and the pressure the turbo sees on the backside, whether it be a chamber muffler or a straight through is miniscule compared to the pressure on the manifold side.

A "tsudo" muffler is about as gay as it gets, I dont care what car its on. Also, two mufflers (resonator and muffler itself) is going to be just as restrictive as just a single chamber muffler. I know, based on expirience, that chamber mufflers arent as bad as "the internet experts" say they are, if that was the case, you wouldnt see anyone running them at all on a turbo setup. Plus, like I said, it would be worth a couple of HP to get the sound you want.

There is a lot more science to it than blowing through a muffler to see how well it flows

Backpressure of any amount is not beneficial in any way, especially on a turbocharged vehicle. I'm a vee-dubber and absolutely love VW diesels, and the most popular mufflers by far amongst the TDI and TD IDI crowd is none at all. Most people run 2.5-3" downpipes with aluminized piping of the same diameter all the way back, and nothing else. These are 1.6 and 1.9 liter motors pushing 30+ psi of boost and putting down over 300 ft/lbs of torque (and still getting 50 mpg), any kind of backpressure or restriction is detrimental to performance and reliability.

Also, exhaust tube sizing is also critical to overall performance, as too large of a pipe will kill the exhaust system's ability to scavenge waste gases, which leads to all sorts of undesirable side-effects. On my '82 VW Rabbit diesel (N/A), I used a dual-outlet manifold off a 91' GTI, fabbed a custom y-pipe into a 2 1/4" straight-piped side exit. after junking the ridiculous single outlet "toilet bowl" manifold and 1 3/4" factory exhaust system, I've noticed a significant reduction in operating temperature along with an increase in both power and economy (around 45 mpg or so).
