If I remove the stock muffler and replace it with an aftermarket one, but leave the piping/cats/midpipe alone?

Specifically on the freeway 65-80mph

Any advice is much appreciated

 

Depends on the muffler.

 

No baffles or walls, just a straight through design with stuffing (glasspack?) inside

edit: my buddy sells this at his warehouse and im looking for a cheap alternative for a little sound/looks

 

hmm u mite a tad bit, but not really that much bro. if u dont touch the midpipe or the cats, u will not drone a hell of a lot, but you will still have some drone.
what muffler are you thinking of getting

 

thats a pretty sleek design, yes with that u will a bit.

haha it says that you will gain 10-15 hpp

 

would a traditional catback like the Megan OE-RS drone just as much? I assume so since it changes the piping

 

you wouldnt get alot, if you were to take off the resinators then yes you would, i took my resinator off of my coupe midpipe running stock muffler sounds nice but around 4-5k it drones then goes away.

 

yeah all the ebay muffler ads say that hahaha, i'd be getting it just for looks/sound

 

yeah, i hope you're not expecting the "10-15 horsepower gain" lol

like 4drgreatness (i feel silly writing your sn vivek) the muffler will add a bit of drone. if you mess w/ the midpipe and stock resonator, that will significantly add drone.

 

hmm not sure because i havent heard the megan one!! i have the stillen dual exhaust. It does drone but nothin unbearable. I also have kinetix hfc and dc headers, n im still not that loud, lol

 

I see, with HFC, headers and a catback I would of thought the drone to be unbearable.. but everyone has different ears and thresholds especially if you're used to it

 

^ yup!!!!! well on the freeways just keep a constant speed and u be good!!!!

 

y u feel silly?

haha im contemplating 4drmadness again loll

 

imo it will drone because there will be no resontor but u cant go wrong with the price on that part. If you dont like it, you can always just put back ur stockie.

Go for it!!

 

Yeah I imagine the drone to be minimal if anything, will probably jump on it. Thanks for the advice fellas
