exhaust system
I am new to this site and a new corvette owner...my first. I wanted to upgrade my exhaust system and I have a convertible 1989. My question is will the dronning from the Borla be just to much noise over a Magnaflow system. Thank you all for your assistance

If you're concerned about drone Corsa is the way to go.
In my experiences with magnaflow and borla on other car (mustangs, fbodies) Borla drones less and sounds better |

corsa, corsa, corsa!!!

procharged 95 here,shorty headers,no cats and magnaflow #16837 3" cat back system.absolutly no drone at all.

This deal about only Corsa doesn't drone is horse poop. The stock system doesn't drone, at least mine didn't. If you leave the cats in place and go with any standard type muffler with one working outlet it won't drone. Corvette Central sells a "no drone" OEM style muffler. www.corvettecentral.com

I went with a true dual chambered exhaust with chambered muffler eliminators from Allens Exhaust. I get no drone at highway speeds or cruising in town. Sounds great at idle and sounds better when you get on it a little. Just my opinion.

(BADDUCK) :iagree: with your statement, but what you'll end up with is a stock sounding system. the OP's topic is upgrading his exhaust and the drone issues between magnaflow and borla, not stock mufflers. forum members with real world corsa experience pretty much state no drone with the corsas. i have had four corsa systems (1990, 1996, 2000, and 2008), and can tell you that i had zero drone or resonance from my corsas. i have also had one magnaflow system and the drone was frickin' unbearable! BTW, my son's 85 has corvette central "stock style" replacement with TWO functioning outlets, and they actually got better sounding with age. they really do sound pretty good, and no drone.

What good is a forum where everyone says Corsa, Bosch III's, and AFR's. You don't have to go to expensive stainless mufflers to UPGRADE.....JMO.
Seriously, that's a great point...I typically try to suggest reasonably-priced alternatives in the same regard. Chambered tubes, performance cats, glass-pack muffers, X/H pipes are all good examples of reasonably-priced add-ons used to quiet sound/drone. Glass packs are sometimes frowned on as Vizzard says canister mufflers can rob some power. People also seem to think converters are always really bad for power. Chambered tubes, spiral mufflers, and other unique approaches are rarely mentioned...maybe they should be. Either probably robs way less power than potential buyers might suspect. People who drop the coin for the high-dollar stuff are usually enthusiastic about the brand. Corsa does sound like a good option thru repeated support. So, you COULD assume that means FIC, AFR, and Corsa really are effective solutions. Otherwise, they wouldn't be mentioned so often. Also, vendor's selling the higher-priced and/or more sought-after products usually have done a better job of advertising and selling their parts. |

Put front cats in. It will help. Magnaflow aftermarkets about $150/pr + installation.

ok let me put the question again in a diffrent way: what is the quietest mufflers that would give you close performance to the magnaflow?

i'm somewhat enthusiastic about corsa, because it gives me the sound quality i was looking for - not loud enough to draw too much attention, and zero drone. another reason is the fit and finish. corsa's are pretty much "plug and play". can't really say that about magnaflow - on the Y-pipe, the distance between the R and L manifold mounting flanges was about .75 inches too narrow, the flange holes were way over sized requiring an extra cost, thick specialty washer to secure to the exhaust manifolds, the magnaflow front y-pipe and the magnaflow main cat wouldn't mate and i had to have the y-pipe expanded (probably around 1/8 inch) to get a good fit. then, top it off with the drone. corsa, on the other hand, a fit perfect - all four systems i've had. i really don't know any vendors that push corsa. they just don't sell enough of those systems for the extra effort. people with real world corsa experience push corsa. nobody is twisting anybody's arms to buy corsa, and you can pretty much buy anything you want. if you want to go inexpensive, go for it. my feeling, it doesn't cost anymore to go first class, ya just can't go as far! :lol: "What good is a forum where everyone says Corsa, Bosch III's, and AFR's" - ??? - first of all, NOT everybody says that, but when 9 out of 10 people do - well, you can take that FWIW. i really have to quit spending any more time on this thread, move on, and finish reading my book on ODD - :D |
I'm surprised I have not heard of anyone on here trying the Dynomax VT. I plan on doing it in the near future. They are $100 ea with a 30 day return policy.
I've had good luck with my Corsa system, or really just mufflers. I bought it used and sold the resonator with no added drone as a result. 408cid, headers, no cats. There have been many less expensive alternatives that have resulted in no drone, the only problem it seems to be different for every person. Plenty of Magnaflow "no-drone" claims but the specifics of system and the application all seem to be different. You basically have risk-reward decision to make. You can try and do it for $200 - $400 2-3 times before you hit the Corsa cost. Problem is, if you haven't found the right combo yet, you're going to be spending more. |
First of all, let's make sure the comments you read are from non LT1/4 owners. Their exhaust systems are different than yours. I'm a LT1 guy so my inputs wouldn't really help you. Just for grins, I went through a lot of exhaust systems and found that I really like the OEM system with muffler elims and a cross over aft of the resonator. Great sound. What you need to do is follow what guys have tried and like. Nobody wants to admit they made a bad buy so beware of the guys that have made high priced systems and rave about them. Hey, I was one of those guys when I bought the B&B system which is now hanging in the shed. Go to car shows that have Vettes and ask to hear their systems. They love to show off. Good luck with your search. :thumbs:
