Default how to get the hum sound?

I have a free flow exhaust and the stock catcon and muffler have been replaced by custom built perforated mufflers which provide a free flow of air but at the same time reduce the sound.i tried removing one of the mufflers but it only led to the car producing a diesel car sound.i have seen a lot of ohc,esteems producing a mellowed roaring sound like what a superbike produces.how can i get that sound.i had changed the headers earlier also but they got damaged in an accident.so am running on stock headers and a freeflow exhaust.kindly help

Hi,

Can you explain what you mean by humming. The sound a car develops is based on the state of tune the car is in and also the engine size, that aside a lot can be done to get the desired sound also. Main things would be playing around with the muffler specs and the expansion size. The longer the expansion the softer the sound as a thumb rule. If you want your performance switch back to headers.

BTW which car do you have. Contact Autopysche he should be able to solve your problem.

Viper

PS - what do you mean by perforated mufflers.

by perforated mufflers(i.m sorry if thats the wrong term) i mean,that the inner tube of the muffler has holes in it at to absorb the sound.well even i thought so that the sound is characteristic to the state of tune and displacement.but i saw a zen with the same sound with just exhaust muflers.well i have stock headers,the first muffler has replaced the catcon,and the 2nd muffler has replaced the stock muffler.the exhaust pipes are stock and overall diameter was not increased as it wud have led to loss in low n mid range grunt.I got the mufflers installed from Performance auto,noida and the the mufflers are branded as Remus.wen u hear a superbike u hear somethin like a turbine spinning or something....the best way to explain is just relate it to the sound of a superbike and ul get the picture.i wud go to autopsyche but he is just too far away(gurgaon).and i'm talkin about my zen.

Hey remus is a good muffler and should give you adequate sound. Maybe the installation was not done properly. Why dont you go back to preformance auto ppl and get it re-checked.

dude the rumbling sound is all about it man... thats what makes the whole sound so special... even the astons ve em
neway wat u want is a performance header and then a straight pipe connectin to ur exhaust and ull get a crisp roar .. what i guess is your looking for
just adding mufflers is not gonna do you any good ... tried and tested on my pailo 1.6 so tellin ya and plus your throttle response improves too

Well im getting a custom muffler for my car so as soon as i get the sound that we both like i'l let you know exactly what was done.

What does the performance GURUS here have to say about REMUS exhausts? Is it worth paying 15k?

I'm planning to get one for my Alto LX. Any recommendations?

SZ - I would be very surprised if you are getting an original Remus exhaust. And anyways spending 15k for an exhaust for your Alto is not advisable especially if you are not a performance freak!!

P.S. If you are getting an original Remus at that price & are sure about it then it's not such a bad deal!!

Remus end can would cost you about that much... so would a Magnaflow. However speedy i dont think it will be of much help on an Alto, i would rather have you spend it on something more value for money on your car.
