Default Recommended mufflers for C4

I just bought a 94 and it came with the two back mufflers missing.....just two curved pipes from the exhaust tips up to the Y.......and the car is really loud....too loud for a daily commuter.

So, before I buy new mufflers......are there any recommended name brands?

Chevy dealership? Midas? any repair shop that I trust? or is there a Muffler Specialist for Corvettes? Does it really matter?

Personally, I would like the car to be quiet. My job is stressful enough......a quiet ride home is nice....knowing that when I need the power, I got it.

Sent you an email regarding some "factory" exhaust! This isn't in the email! You're "local" and I'll let you "try it before you buy it"!!!

DO your research. I would look up sound clips on youtube to see what sound you prefer search Flowmaster, borla, corsa etc etc. You can buy just the mufflers from any manufacturer. I will call you a morron if you go to the dealer and ask for mufflers they will charge you $XXXX for factory replacements.

If you want it to be quiet and no resonance drone, your options are either stock mufflers or corsa.

I like Magnaflows but I dont think they'd quiet your exhaust, so best just to look for some stockers.

I'm surprised that no one else has said this, so I will. (Need to get it out of the way first! )

OMG! If you drive a Corvette, you SHOULD want to drive a sports-car. If you want a quiet, non-stressful ride home from work, trade it for a Caddy.

O.K., I feel better now.... First thing I'd want to know is if your center resonator is still in the car. If not, replace that first -- before going any further. A muffler shop would do it for the lowest cost.... way lower than a dealership. (BTW: I agree...buying anything from a dealer is stupid. It will cost you too much. OTOH, these fancy, name-brand mufflers cost too much as well. But, at lease you get a better-designed muffler. IOW, they flow better).

If the resonator is still in place -- and you MUST go quiet as stock, try muffler shops on that too. I wouldn't be surprised if that was $500 less than dealer or name-brand sports mufflers!

If there's room for some growl, Corsa is the commonly recommended after-market, name-brand option. If resonance is the issue, you might also consider resonator tips -- like these. If that doesn't satisfy you, you could always replace the resonator with a generic muffler (afterwards).

BTW: The mufflers I linked above are for older vettes that have smaller diameter exhaust. But I believe you can find slash-cut resonators in raw form. (I found them a few years back anyway).

If quiet is the goal you can get someones stock LT1 take offs for cheap and they are quiet. I just did it on mine and can here the air sucking into the carb(not exactly stock)

That will buy you some time to shop for the right sound

Best = None

Actually I have factory mufflers. They just happen to be installed in the storage area over my garage.

I would reccomend putting mufflers on. I don't understand why people don't want a refined v8 growl instead of a 60s garbage low tech machine factory sound.

I had stock exhaust on my 93 when I had bolt ons and with headers and no cats it sounded phenomenal. Try to find someones take off system thats local to you.

I agree



The stock mufflers flow extremely well w/o any resonance.Sometimes I think they are too quite.You could probably pick up a set for $50.00 bucks or so and have your local muffler shop install them.

I think Walker Dynomax LT1 Corvette system mufflers look stock and sound stock.

I have been called a lot worse! ha ha.......Good ending to the story....A forum member picked up on my thread and dropped off a entire exhaust system from the Cats back......had it installed and WOW. Now I can hear all kinds of other noises coming from the car!

However, with respect to the dealer issue.......I have been a backyard mechanic for about 30 years and NEVER would go to a dealership until about 5 years ago......long story......But, I have actually had some very good experiences with them, especially with the quality....not on all parts, but definitely on some.....I do not what has changed, but it some cases they are competitive with the price and in my opinion a better quality.......bottom line is that I tend to shop around and ask questions before buying and a lot has to do with the specific part.
