Building custom axleback - help with muffler choice!


Recommended Posts

I have a catless DP and 3" custom midpipe/y-pip with a Megan Racing resonator in the midpipe.

 

Right now I am running stock mufflers but would like a deeper tone exhaust. Something similar to what the prodrive mufflers provide. The autospeed CBE also has a nice deep tone. I know the combination of the resonator and mufflers determines the sound, so it will be tough to reproduce those exact exhausts.

 

My question is, is there a particular muffler that is known to provide a deep throaty tone vs. others? I have been looking at Magnaflows, and I know there is Borla, Thrush, and others.

 

Is there a specific brand that is known for deep throaty mufflers? Does it come down to muffler design? I don't have a problem figuring out what size I need, etc... I just want to know if there should be a brand or style to shoot for in order to get the deep throaty tone.

 

Thanks!

I have maganflows like the one linked above custom mated to x02 mid/y Sounds a little too loud for me.

 

I am guessing you have no resonator in the mid? Anything w/o resonator is loud. I have a pretty long resonator in my 3" mid, so that will help.

If you DO have a resonator, then yes, I would be concerned with these mufflers since our setups will be about the same.

I've got custom magnaflows mated to the stock mid/y pipe. Everything upstream of that is aftermarket. Volume wise, its great, not too loud at all and absolutely no drone. I would like a deeper tone though and am considering going to a full CBE in order to do that. Just don't want to increase volume or drone at all so it will be kinda tough.

My mid/y is resonated. but its loud for my tastes. all my friends say its not too loud and it sounds great.

Right now I am just a bit louder than stock... its nice, but not mean. I love the rumble that comes along with the Autospeed CBE or prodrive mufflers.

 

I just cant afford prodrives, but love this deep note:

The Autospeed has a nice note too:

So this is what I am trying to acheive. My custom midpipe and y-pipe were inexpensive to have made... so I know they will throw on some mufflers for super cheap. Now, I just want to find some that will give me a note that is similar to the exhaust notes in the vids above.

I've got Magnaflow 5x8 mufflers (part #12216) with no cats. It is pretty tame with normal driving and a nice rumble when you get on iy. It's about 1/2 as loud as the cat-back they make for the legacy. You wont be disappointed.

 

This is the only video I have. In car 30 - 100.

This is what he listed on youtube:

Dc Sports Up Pipe

Invidia HFC DP

X02 Mid and Y

Custom Vibrant Mufflers which mimick lachute's original design.

 

They look like the mufflers with the oval tip.

 

That is correct, that was my old setup on my 05 5eat.

 

I never thought that video was still being viewed lol.

 

The mufflers are http://vibrantperformance.com/catalog/product_info.php?cPath=1021_1031_1053_1108_1195&products_id=1155

 

Apparently they were lachutes old design. They are very bassy, and make no mistake they get loud. Driving down a street if i got on it the car alarms would go off. If you use a stock mid and y you should be fine though. If you use a 3 inch mid and y make sure you put on a resonator.

 

However there is no rasp which to me is a good thing.

Im going to bring this thread from the dead back to life, in hopes someone can enlighten me.

 

Im looking to take a perrin mid and y, and pair it to a set of mufflers. What do i need to look for in particular when choosing a muffler? What size will fit in the cut outs, without burning the bumper?

 

I was hoping maybe i could pair these mufflers, or something similar to the y pipe, but unsure of size or fit.
