I wasnt freaking out I just wanted him to know that the 500's are the only muffler that i know of that doesnt get raspy when you add longtubes or orxp or anything for that matter, and I know you were recommending them, I wish I knew more about them when I first bought exhaust parts, i had to do the trial and era method to get the sound I wamted, which is the sound alot of people are looking for, some people like the rasp crap but I hate it..

I had lots of problems with my Flowmasters once I got rid of the cats. After a year I got GT500's on it and no complaints now. It's loud once I get the RPM's up there, but not raspy or metallic/popping sounding.

Helmholtz resonators. Google it. It's not common at all, but it solves the problem with physics. Will get rid of drone in any exhaust, as long as whoever makes the pipes does the math correctly.

Only con about the GT500s are that they are heavy. That and they look like **** from behind unless you paint the cans. Also......I hate the tips,almost to the point of having some rolled ones welded on.

Canada....

On another point, the tips on the 500s are a little low rent but, I like the fact they are huge and fill the hole nicely.

I did paint the entire can w. flat black BBQ paint so you can't see those parts from behind. Big improvement for low cost, just like the 500s themselves.

The mufflers are a bit tubby because they have to last 100,000 miles. That's the standard expectation of an OEM exhaust component in durability testing. Saving what, 20 pounds here isn't really a big deal on a 3600 pound car.

I'm Not a fan of Rolled Tips either, and I can't say I've seen a better looking tip than these Pypes 4" double walled SS tips. And they stick out far enough to see the Pypes name embossed on the top. I don't want something that just comes flush w/ the Facia. If they could just engineer the "Drone" out, I'd be as Happy as a Clam!

Well, we're speaking the same language about 'Rust'. Thank God they did go to SS exhaust systems--I've replaced many "aluminized mufflers" and exhaust pipes over the yrs.
That's one thing I thought detracted from the rear view of the car, were those big stock mufflers hanging there. Great idea, painting the cans Black. But w/ these 4" Resonator Tips, they fill up the hole and there's nothing else to see.
I put mine in, when the snow starts flying, and drive a van in the Winter. But the extra wt of the GT500's should give you better rear wheel traction--Summer or Winter. LOL

I had the roush as my first muffler, but as soon as I added the 3" heartthrob cat to axle with flowpacks, the rasp became a huge annoyance. Since then, I switched to the RTR mufflers and have never looked back. They sound great! I also added kooks long tubes and sidepipes with QTP electric cutouts.

My exhaust videos are below:

Do the GT500s ever go on sale? I've been looking on american muscle and late model resto for several months waiting for a deal. With no luck.

I doubt it. Especially considering the already low price compared to other axlebacks. Once you hit 50 posts PM Dan or Shane from AM and they will give you a discount code for an extra 6% off

I wanted the RTRs for quite a while. There's a unique sound to them, and I love the tips. I scored a really good deal on a set of Flowmaster 40-series with some custom pipe work/H-pipe. I reeeeeally like it, but once in a while there's a real rattle. Tinny sounding. Only when the engine isn't under a load. I looked at the GT500s, and to be honest I'm debating swapping...that price is unreal, and with 3" catbacks, h-pipe, and possible LTs in the future (maybe cat deletes), I think it'll sound great.

Hey Brian, do you have any stats about 'Back pressure' on the GT500s compaired to the Axle-back Resonator design?

Huh??? Axlebacks are just the mufflers. Has nothing to do with back pressure. No axleback will gain/loose you any hp or back preasure. The resonators are a different part of the exhaust, used to help muffle the exhaust. Some get people get them cut out to pick up a bit more sound. The only parts of the exhaust that will make a difference in back pressure and HP will be removing the cats, which will pick you up around 15hp on the dyno, and by switching to long tube headers.

Are you saying that there isn't any difference in 'back pressure', between the GT500's (which I assume is a Chambered muffler, like the stock mufflers I took off my GT) and the Axle-back Resonators (Pypes Pype Bombs), which I replaced them with?

There should not be a change in back pressure. The only option that may affect back pressure would be going with axle backs that have a 3" inlet and piping instead of the stock 2 3/4" inlet and piping. I went with 3" all the way, and it seems to flow a lot better. This will definitely help if I go forced induction.

Exactly correct. You also got rid of the resonators when doing that as well.

I actually went with the heartthrob cat to axle kit with flowpacks in the mid section. They still have fitment issues, but for the price, I didn't mind the 15 minutes of cutting the pipe to the correct length.

Do you have the Stick or the Automatic? I called Pypes again and talked to someone different.

Autos tough as drone can't be varied or controlled by selection of gear as easily and the car'll tend to hunt itself into the drone through the action of the torque converter.

Anyone whao has an auto should be very wary of any kind of drone producing exhaust, as it'll be way worse than on a manual car.

I love my Roush exhaust..just installed it and it sounds bad ***. It has GREAT reviews and really worth it IMO...especially since I didn't wanna spend a buttload on Borla.

I used to have a set of Tanabe Gold Medallion exhaust (for my previous import ... I know I know).

They had a design that you could insert an included piece into the exhaust tip that essentially acted as a silencer. However I'm thinking this can't be good because it effectively narrowed the flow diameter.

But it was very effective. I never drove it more than 1/4-1/2 throttle with it on but was useful for long road trips.

Most exhausts come with a pre-drilled hole. Not sure if it maybe possible to fabricate this "silencer" and bolt it on.

Yeah when I started this thread that was what I was looking to hear. A way to plug or insert something in them. I have since decided to go with a set of GT 500s instead. Thanks for the input though.
