Go magnaflow universal and keep the resonator. Sounds really good.

 

no. that is the muffler, it is where the old resonator used to be. so yes it is removing the resonator, because it is not longer there. coming out of the muffler is 2.5". the tip is the stock tip and it is where was orignally. maybe this video will help out. its not a great quality, but you get the point. it was taken before we took the car off the lift.

how restrictive is a resonator anyway?

 

little to none. it works based off the principles of sound wave deflection to achieve a lower volume level and more mellow sound.

if you guys want to replace the resonator with something that will still deflect sound look into the spiralflow moroso mufflers carried at Jegs and Summit Racing. we use them a lot on turbo cars, they work great with no restriction added, and are about 50 bucks

 

yeah, thats what i thought. i can see replacing the baffle muffler for a straight through type, although, i'm sure it's minor even then, the SS and SS SC have pretty performance based exhausts

 

yep, pretty much

consider this too: the two highest flowing mufflers on the market (at least they were not very long ago) were not straight through designs. they were built around deflective theory and looked like a chambered style muffler.

I would possibly put two of those spiralflows on there, one in place of resonator, and one in place of rear muffler. that would be very smooth and clean sounding, and rather quiet as well, but perform great.

 

any approx cost? i wouldn't mind getting a little more performance out of my pipe.

a lot of people think that there is some magic amount of power hidden in the exhaust. most factory systems are not THAT restrictive. i just want an excuse to weld something.

 

hahaha man after my own heart

the sprialflows are like 50 bucks a pop, come in 2.5" at the smallest, which should be perfect for you guys.

my buddy built an exhaust for his girlfriend's car and used only one with no other sound baffling and it sounded better than 75% of the custom exhaust systems I have ever heard.

on a lot of the earlier cars I've worked on they were pretty damn restrictive from the factory, but I think GM kept performance in mind on the delta platforms for the most part.

here you guys go

 

link perhaps?

 

I put them in right after I posted lol

 

that's kinda neat, they should, however, make one in stainless.

 

Well lets do a side by side comparison.

Stock Exhaust with Magnaflow muffler in place of resonator.

Take note of the size of the pipe comming from the Cat.




and SS exhaust (again note the increase in the size of the pipe comming from the cat.



The piping on the SS exhaust is larger. Better flow and I've noticed a performance increase.

 

I just got the same magnaflow muffler in the mail today, im gonna just put it in the stock muffler place (with the res) i hope it sounds as good at yours, very nice.

 

Magnaflow Resonators

no that is replacing the resonator because there is still something there, removing the resonator is running straight pipe in its place.

 

so what if i moved the muffler to where the stock muffler was? would it then be considered removing the resonator? this is pointless to argue over. bottom line: i have no resonator

 

Does any one in CA know if this will hurt the SMOG. I dont think it should only because the resignators are for sound and not emissions, RIGHT?

 

the only thing it will effect is noise levels. you should be okay with carb crap

 

i think the exhaust sounds whack

 

has anyone flamed you for your exhaust? i have a similar setup, catback exhaust but i have a magnaflow oval muffler and its not where the resonator was, its where the muffler was. i have a video but most people just flame me for the sound/learning how drive stick. i dont think mine sounds worse than yours(not that you have a bad sound, i like it.) the camera kinda distorts the rev in the beginning it doesnt sound exactly like that. and my exhaust seems to ''rumble'' a lot. does yours do that? on deceleration?

to the original poster- i would say dont bother with resonator, just change the muffler. butnot flowmaster. it sounds like crap if you dont have a catback.

 

If all you want is sound, then just replace the muffler only. It is the cheapest, easiest way to change the exhaust sound and JUST the sound. Biohazard had a TenzoR can on his car first before he went and ripped the rest of the stock pipes out and it sounded very good. Leave your resonator alone.

 

Those resonators are just Magnflow's version of a glasspack. Save some cash and go to Walmart and buy the original Cherry Bomb glass packs. They are about $25.

 

lol buy a cherry bob oval muffler and put it on there...lol i had one on my old cobalt for like a month. it was pretty quiet. was only 18 bucks.

 

yea some people dont like it. but i didnt do it for them, i did it for me. i like the way it sounds except on a cold start its a little bit raspy. it sounds alot better now then it does in the vid. yea my exhaust does crackle when you let off the gas at high RPM's or when i down shift to slow down. i love that!!

 

Hmmm .... from everything I am hearing the resonator should stay in and just change the muffler. you guys have a set up that you could save more money. Go straight pipe for that is what it sounds like. put yourself next to a honda and you sound no different from a RICER Roni Treat.

you need to seperate yourself from the asian flare or flame. people are giving you looks cause of the noise polution. Most people will turn heads if it sounds like a tight tuned car if they appreciate cars and those who dont wont be bothered. if your bothereing people then your exhaust does not sound good. it should only get loud when you get on it. stick with the stock resonator and put a good magnaflow or Corsa on it.

I heard Zomghax exhaust. it was a little louder. defintely deeper. He did rip it wide open but I new it would be louder than stock but as he said it sounds quieter and cleaner but deeper. it was a good sound.

 

i understand where your coming from...i know it has to be quieted down some because of my ticket (look at my thread: https://www.cobaltss.net/forums/2-4l-le5-performance-tech-46/need-help-fixing-my-exhaust-too-loud-33637/ ) im trying to figure out how to go about that right now
