the vid description explains why and how i got this. long story short, got it running very crapily last year, threw on a cheapo muffler and a hunk of pipe just to get by without getting pulled over in the city but now the car is running well...and i want a better exhaust.

That sounds funky! We need some pics of this "sucky" exhaust.

 

 

I really like my aerochamber, it's not raspy at all.

 

do you have a vid per chance? you probably have the same motor i do. 355 = 350 bored 30over? am i right?

 

furthermore, with the setup pictured above, i think i'd like to just try and swap out the muffler instead of just investing in a sound engineered [and expensive] catback.

i think the actual reason my exhaust sounds so goofy is because of that muffler. it's like a generic flowmaster...but was sitting around the shop. it's just a single chamber open piece of crap.

does my logic make sense? in that i can totally rid of that raspy-ness by putting in a nicer muffler? or am i wrong and it the way the 3inch was ran that's causes it to be so raspy?

 

or....is this the issue? is this thing all piped wrong? lol
i remember the dude saying it didn't matter. the only way i could see it not mattering if the muffler is just hollow. lol.

 

Well, I believe that the top input on the right side is the outlet and the bottom input is where your exhaust enters into the muffler.

 

that's what i'm thinking. in "in" should be the solo nipple on the muffler, while the two on the right should be the "outs"...which isn't my case.

 

here's my "intro to myself" thread if anyone's interested.

so your saying that your not sure you have a "crossflow" type muffler?

 

I believe what Delovont is saying is that the connections on the right need to be swapped.

 

there should have been a arrow or labels on it, i have a flowmaster, and without a cat it sounds just as raspy!

 

all are possible. i guarantee u this muffler is completely hollow. the exhaust soudns so bad...lol. and, assuming i am correct about the muffler being empty, the in/outs don't matter. i'm gonna change the muffler, and it's it's still gooftarded, i sold myself this morning on the gmmg catback.

 

hard to tell what it sounds like backed in a garage. But to me the vid sounds pretty good.

 

as long as that is a 80 series muffler it is piped correctly.


here is a cutaway.




the outlets are directly across from each other and the inlet is offset.


I can't watch the video at work though..

 

I know I have the same muffler, I hollowed it out just to see what it sounds like, and it sounded exactly the same. I was very surprised, but I really like the sound of a 3in cherry bomb glasspack, and I also like the sound of the super 44.

 

finally saw the video, that sounds like a new Flowmaster 80 series to me. It'll change tone after you get some carbon buildup in it.

 

the vid makes it sound better i think...lol...

i will take another vid when i warm it up again tomorrow...but not from in garage. i'll open the door a bit and stand 20 yards away. sounds like poop...lol

 

it's been a year or so. motor was just put in, but i drove it all last summer with old motor but with this exhaust.




it's too loud to be an 80 series...also, it's a generic muffler, not a flowmaster.

 

I remember a local shop trying to sell me a "V Force" for mine about 8 years ago, same internal design as an 80 series.


Have you watched some other videos on youtube to see if they sound like yours?

 

is that a thrush welded muffler? if it is i had the same thing on my dodge ram and it sounded like crap. i took it off and now it sits on my bench.

 

yea...it sure isn't a flowmaster 80 series. i will try and get you guys another video like i promised.

 

finally got that other video. i'll up it to youtube in a few and share.

 

my magnaflow is piped different than yours is. the bottom on the right is the inlet. then the outlets are the top right and left.

 

about to up my newer/better vid to youtube, but it's like...under maintenance...but yea...stand by =)

 

well...it's uploaded...but pending due to site maintenance. maybe i'll still be up when it's done.

here's an updated vid...the exhaust sounds alright (nice and mean) under 2500 and while idling. but when sustaining rpms anywhere above that, it sounds like a civic with a coffee can muffler. i used a real digital camcorder for this, and it still isn't catching all of the sound...but yea, that poppy noise is what bothers me...(not referring to the backfire pops...that's badass)...

 

hmm it sounds like theres no restriction in the muffler at all it looks like a can with pipes coming out of it no offence im ust saying that from the way it looks, i would say go with a magnaflow catback

 

don't wory about offending me. the title of this thread is "exhaust sucks". i totally think it's just a hollow muffler looking thing. i am gonna have them swap the muffler out, and see what it sounds like then...before i spend like a grand on that gmmg catback exhaust i want. a muffler swap will be less than $100 if i bring the muffler in.
