Drag Racing Tech - Race Mufflers

I need some race mufflers.
Race only car. I don't like open headers, too loud for me.
I know it adds weight but.
Headers have 3.5" collectors. I had the Dynomax Bullets before and didn't like them. I had a Borla XR-1 on a ORY and like that sound. But I don't want to spend $350.00 on the XR-1's.
I'll have about 8" of straight pipe off the collectors and then the mufflers and turndowns.
Thanks

I use the Quicktime Performance Race Mufflers.

2.5"-3.0"-3.5"-4.0"
I don't know pricing.

I like my flowmaster bullets. Kooks headers, 3.5 collector, NAPA stainless steel band clamps, and a little BFH to the drivers side muffer so it would slide onto the header(hits the floor)

x2 . .

Do the 9 inch vibrants quiet it down at all? Want to drop more weight and that x pipe isn't the lightest.

It seemed to be the same amount of noise when switching from duals in front of the axle to mufflers on the headers. It was louder inside the car though but that's because the exhaust is right below your feet.

Vibrants???
Who makes them. I like the 9" length.
Anyone with a sound clip?
Thanks guys.

Plus the flowmasters pay money if you win some of the stuff in LSX. Main reason I got them, but they sound pretty good also.

I used to have the vibrants, didn't do shit for sound to me.

Vibrant turbo mufflers here. 3"x5"

This is a cold start warm up:

if you want to quite it down, id get a case muffler, like the QTP, or a magnaflow 4x9.

Something light and cheap ($15 each) these work great. I know me and ATV racer use them, fits for class stuff. Dont make it any quieter in the car with them dumped, but cut down a little at idle, not much.

I can handle that just fine, thanks for the info. If its louder then I won't hear the gear noise as much it's a win win.

I like my Flowmaster Outlaw race bullets. Flowmaster pays NMCA contingency, that was a main factor in my decision as to what to buy.

They sound good on your car.
Not legal for us at Englishtown but I like them.

I'm the one who posted the QTP thread quoted above. Great muffler, great people. Even with the gear and th400 I still enjoy driving the car around.

ya there legal for LSX AM, and MIR were you just need to have a muffler, and no Db limit.

If anything JL you could make thous easy for 4, 4.5, 5, :secret2: check out the pics of what they really are. Its just 10-20 spots somone hammerd a shape center puch thu the tubing, then there a 1/4 bigger secton of tubing thats kinda over that area :secret2: There not even fully welded, they just have 2 tacks on one end the that outer cover doesn't fall off.

If you look on YB I think a few shops make somthing like them, if you want to buy somthing. I know the high end exhust places have them too, (burrs, SDP, staimless headers, vibrant) But not this cheap.

Not to give to much away, but there dont cost much power, more accounting for the length of tubing they take up.

^^^^This^^^^ Not pricey and they sound good (I think so) I have a video somewhere... I'll dig it up if you want.

Here are the Vibrants I run.
http://vibrantperformance.com/catalog/product_info.php?cPath=1022_1032_1257&products_id=1054

They also make these in an aluminum version with more "muffle" to it that is 14" long.

Very high quality.

They do make a 9" long version of the ones I run(5"). The longer it is the more bite it will take out of the exhaust.

These are what most of the heads up radial guys run when they have to meet a class requirement for mufflers.

I do like the way those flowmaster outlaw bullets sound though, mine aren't dumped but they do extend off the collectors a good 10" and I am having dumps welded on the ends of the 3x5's I have now and then kicking the dumps out at a 45* angle so some of the sound exits out the sides of the car and at the ground at the same time.

As already mentioned, The QTP's, Dynatecks, Magnaflow, Flowmaster will accomplish what you're looking for.

The little bullets being mentioned are only called mufflers.

Studderin what length did you get?

Do understand thd vibrant style and bullets do nothi g really to quiet a car for driving. They're used, for when the rules require it, or for contingency payout (a good way to make extra cash if you run at bigger events for sure)

I want to quiten the car down some. Smooth out the sound.

Yes they won't quieten it down as far as decibels go, but they will take the rasp/bite of open headers out of the exhaust sound.

Longer they are the more bite is taken out, not sound volume. I guess "tone it down" is what I am looking for to describe what they will do.

Yes a bullet or 1 chamber would do you better.

I like the way those Flowmaster Outlaw bullets sounded on BESstrokednova's car. I also really like the way Magnaflow bullets sound buy they are just as expensive as the vibrant mufflers that are actually mufflers as they doe make a real muffler that is still considerably lighter than anything else on the market. I posted the link underneath the ones I have.

What do you guys run for your race car on the street? I want to put a muffler at the end of each of my open header extensions for street use.

I just got mine running and have flowmaster 1-chambers off the headers. It is loud. Sounds ok I guess. I may look for something a little quieter but I don't want to add weight. Will try to get a sound clip up soon.

full out the back, alot quieter in the car. I run the 2OTL all summer, then slip on mufflers for maybe 1-2 weeks in the fall

The Vibrant 3"x5" "mufflers".

I am planning on some bullets and if I can find a good deal on those flowmaster outlaw bullets they are probably what I am going to go with.

I'm the one who posted the QTP thread quoted above. Great muffler, great people. Even with the gear and th400 I still enjoy driving the car around.

I think, I'm leaning more to these mufflers.
Where do I get them at?
How long are they and a ball park price.
Thanks
