Muffler Delete Soon

Planning on doing a muffler delete, from the res back for about $80. The tips are old, I want to replace them.
What size should I buy, and which brands are the best for less than $50? How large of a difference would the tips make?

Going for this.

What do you mean by drone? Also, what size piping/tip should I get?

Drone is when your cruising along at part throttle, (All The Time Fyi) and its just goes "BBBBWWWAAAAAA" Annoyingly and constantly...


No rez,2.5- 3" pipe, small flow threw muffler.. Will sound nice..

You have an m50 it will sing.. My m50 had a prototype magna flow..

Just curious why you think it will drone if it is an automatic

Would not a manal transmission drone also? Exhaust is exhaust independent of the transmission.

No res? Now that's just asking for even more noise.. on top of more pollution. :thumbdown: I'm doing straight from the res back and maybe a new tip.
Throwing these phrases to me.. it will sing? Is this a good thing.. ?

That is true but Exhaust tone is noise produced by the motor...

The motor when attached via a clutch follows the rpm directly, and is quiet at a cruise, hums at part throttle, and pops n' crackles on deceleration..

When attached to a torque converter it sits in the stomach of the motor vocal rang as its not a direct link (fluid coupler) and gives a constant belch!

No crackle on deceleration unless you shift it, and auto shift's sound gay.

We watch people drive by and when they are really loud we listen and can tell MT or disappointment. Anything over a gentle rumble at low rpm's is not a good look for auto's

Its a well known thing.. Some high end manufacturers like mercedes use tuned exhausts and trans shift strategies to help it not do it. But a typical auto car made to loud will sound like that..


You never heard then seen a stock auto honda with a huge muffler?
BBBWWWWAAAAA, BBBWWWWAAAAA,BBBWWWWAAAAA... Threw the crosswalk! BBBWWWWAAAAA, BBBWWWWAAAAA,BBBWWWWAAAAA... Threw the intersection now!

Sooo gay!

LOL..

First off, mufflers are sound ONLY! Catalyst control emissions!

Secondly,

"It will sing" like its sound will become like music to your ears... Duh..

I asked if it was auto, i don't recommend a rez delete if it is.. It will keep it to a humble roar until you dig into the peddle a bit. So should help your cruising tone.



Finally,
I AM NOT BASHING AUTO's JUST SOMETHING TO KEEP IN MIND.

Think that'll sound like the guys E34 in the video?

Be warned an auto sounds as good as a MT in Nuetral.. So don't base it on that unless its moving along..

I will agree that the exhaust note is different between the two when shifting (up or down). However, I disagree that the exhaust note is different based on how the driveshaft is connected to the crankshaft. As you stated the exhaust note is derived from the engine, i.e. the combustion in the cylinders and the exhaust of the gases from the engine. If for example, you have two identical E34s (exept for the transmission), they will sound the same when crusing at, say, 65 mph. Or 80 mph. Or even accelerating, until the shift point. Then I agree that they sound different.

Just my 0.2

In an auto the car upshifts for you, keeping the rpms bouncing up/down from 1500-2500rpm as you go a long.. Bwaaw bwaaw bwaw... As the torque converter spins up..

Vs staying in the gear and riding the scale rpm sound scale up into the musical range 3-6000rpm.

As you get older you will learn to hear the difference.

Yes, and you can have that sound..

The car was in Neutral tho, so no way to check for drone..

My 95 e38 droned a bit with the same motor & muffler i have now, currently i use the same motor no drone cause my e34 is a 6 speed MT

Well, I'm 54 and have been driving for way longer than you've been alive and have drivng auto and manual trans cars. As I said earlier, I agree that the exhaust note is different when shifting occurs. Otherwise, the exhaust note is the same and is dependent on the rpm of the engine.

Not going to argue with you. We can just agree to disagree. Don't want to poison the OP any further

Crazy,

I had really loud cars when I was younger, but now I dig the quiet ones. We accidentally left my E34 idling for 2 days while we were working on the body because you cannot hear it running if you are more than 3 feet from it...

Why not see about retrofitting one of these later BMW mufflers with the valve in them????

^ must be def...?

Don't take my word for it, only EVERY forum has a descussion on this topic! This is not an opinion this is a fact..

At certain resonate frequencies a cars exhuast can vibrate such as to cuase a deep base like sound in the car while cruising, FAR more prevalent in autos.

Its just a FACT, look it up..

Yours may not, but thats the risk.

In a MT car you choose the RPM, in an auto the rpm's hangs around the same range (the drone zone)until you cuase a down shift.. Then sounds equal till the shift, let off and back to a drone.

My uncles flow master Tahoe is a great example.. Most big truck with mufflers do it.

lol, stock mufflers even those are way to heavy, and dont offer enough sound. My buddy had that on his e46 330i says the first thing people do it cork the valve with a golf T so its open all the time.. But its still way to quiet.. Nearly the same..

Lot's of modern aftermarket exhaust systems, except in very high exhaust volume applications, such as high horsepower turbocharged applications, is 100% marketing hype.

We put an SLP Loudmouth Catted X-Pipe and full mandrel bent system on a new Mustang 5.0 Coyote for Mustangs & Fast Fords Magazine in 2012 and it LOST horsepower and torque over the factory system on the Dynojet.

They didn't publish that test despite a volume of photos taken...

Go to Youtube, search E34 muffler delete, for multiple examples of sounds for our cars. I agree with earlier post, do the rear muffler delete and tips, no need to drop the resonator. The rear muffler delete will get you the purr you want, tips are just cosmetic to whatever your taste. Leave resonator on, just my 2 cents. Plus, it makes it easy to reverse, later.

Thanks. Hopefully doing so soon. How about this tip?

Is the 2.25 piping going to be a weird size? Also... if you guys know of any rectangular dual tips let me know, I want some. Otherwise I'm probably just going with these.
