exhaust change

[Stangman]

So thinking about new exhaust for my car. I have 3 inch flowmasters right now and I have run them at the track and taken them off and they dont really hold the car back much. That being said the drone is just to much. I would rather sacrifice alittle bit and be able to hear myself think. What is everybody running. I really need to hear the different sounds whether they are Borla, Magnaflow or whatever else is out there. I dont want to make up an exhaust and not like the sound.

There is a thread about a dozen back that covers some of what you are asking about.
Pype’s exhaust systems used to have audio of some of their mufflers. I have one of their stainless x pipes with built in legs for cut outs. Also some of their mufflers. It’s a 2.5” system.

[Stangman]

Missed that thanks. It would be nice to hear more systems. Doug’s does sound nice.

Barry R's car is the best sounding FE I ever heard, but I don't recall what he was running. I'm almost sure he's running a full 3" system, but don't recall the mufflers.

I run Magnaflow system with tailpipes 3 inch with an x pipe quite loud and has a different sound but I can live with it. I have some vids on youtube at Beraver. Search hbomb49

Quite some time back I used some Flowtech Afterburners on a mostly full exhaust - turndowns at the rear axle.  Had a good sound IMHO.  Right now, it's 3" short bullets with turndowns on the end right under the seats, so not the current guy to ask LOL. 

[Stangman]

I now have 3 inch to a 3 inch X pipe to 3 inch Flowmasters and 2.5 inch tailpipes. I was rushing around at the track and needed to take the exhaust off and cut the tailpipes off so now the exhaust has no tails but has over the hump and pointing down. The 2.5 were a pain in the ass near the rear leaf spring eye in the back. Although I do have old time shackles.

Car sounds nice Harry

here is my 427 with Pype's 3" X pipe, Flowmaster 40's and 3" to the end. With FPA headers. Somehow I got lucky with no drone sounds.

Thanks Doug it is Doug right. Love the sound of flowmaster.  No drone you got lucky, Maybe it’s the shorter system on a mustang?? Well either way she sounds great.

I'am pretty sure i have the same flowmaster's as fairlaniac mine are only on a 2.5" system atm i have an x pipe too sound real close to that note no drone and not bad inside the car.

If you listen to some of the videos of vehicles I have on my Youtube

The Oct 1 of my Mustang is 3 inch with Borla ProXS and a H-pipe on a 489

New exhaust 445 with my red truck is 3 inch with a Y pipe and Jones Full Boar

All iron 68.5 Cobrajet is a 462 with Borlas and an X

There are some others, ask if interested.  I am NOT a Flowmaster fan, in some of them, my Mustang and the truck has Deltaflow 50s, and it sounded great outside, but rattled my head inside, even under the bed of the truck

[Stangman]

Some nice sounding cars in your stable Ross. If the Borlas are quiet inside the vehicle then maybe I will try them. Never heard of Jones mufflers. Doug likes them on his stang also.

[My427stang]

Thanks, I love the Borlas, but the core is slightly less than 3 inch, the Magnaflow on my buddies 68.5 are also quiet inside, but are almost consistent 3 inch core.  Might be a smidge better deal, but regardless, I think I gained power with the Borla

FYI - Any absorption muffler will get rid of the drone.  When Flowmaster advertises sound waves being reflected, energy cannot be destroyed, just changed to a different form (High School science) so the Flowmasters convert some sound energy into heat, and the rest is absorbed into the body as mechanical energy.  They have to vibrate, it's the only way to get rid of the energy, when you hit the right combination of load and rpm, you get the resonance. 

I still have the brand new 50 series on the shelf, I tried them a few times, always took them off.  I want to love them, just can't LOL

I run the 3 inch version of these and absolutely no drone and not as loud as the old Flowmaster 2 chamber mufflers. A totally different sound. See if I can get a video clip of them on my car.

Here is an inside sound video just after I had installed the Pro Series mufflers.  1985 Mustang LX coupe with 550 HP 427 Windsor.
