Corsa's Anyone?


Recommended Posts

The Flowmaster 70 3" single-in/2.5" dual out on my '03 4.8 RCSB was fine when I first got it, but since I added the Radix s/c, it is too restrictive; robs power and doesn't even sound good anymore. I am considering going to Corsa for a replacement. Has anyone tried them? How are they as far as sound and flow? My first preference was Dynomax, but they don't make a muffler with an offset entrance 3" pipe. Also, Corsa CLAIMS to eliminate in-cab resonance via some proprietary design. Is this effective? Any information and experiences would be welcome. Thanks!! :mad:

 

Peace and Coolness,

Sounds almost political: 'CORSA' -- 'CORSA'. Be sure to let folks know just WHICH Corsa. There is the touring and sports verison. There is the single exhaust, there is the dual exhaust.

 

One version is very raspy sounding (I called it East Texas Bubba truck sound), the other is more refined sounding. None have resonance, but one version can be so raspy that even there was resonance, it wouldn't be heard over the rasp.

 

Just my opinion, y'all!

Magnaflow has 3" offsets, and they're reversible, so no worries :mad:

 

Scroll down and look

I gotta go with Dolan here, Magnaflows rock! I like the corsa mufflers too, I drove a dealer demo Ext. cab Z71 with the 5.3L and a corsa side exit setup. Sounded good, but it cost too much to suit me.

 

Good luck!

it would seam their propietary design must be in the muffler itself, so can you get just a corsa muffler? i can weld up my own aluminized system for $50, but haven't been happy with my past choices in muffler because of the interior drone.

You cant get a Corsa muffler seperate. It sucks but thats the way it is. Otherwise everybody would buy the muffler and not the million dollar cat-back.

D**n !! I didn't know that. :mad: Well, so much for that idea! Guess I might give Magnaflows a try, as several people seem to like them. One other question though. I really like the Dynomax Ultraflows, but they don't seem to make one with an offset inlet pipe. Would it be advisaible to try and put in my own offset? Or will the bend be too restrictive?

Yeah, it sucks. I searched high and low for a Corsa muffler. Lot of f-body guys dump the Corsa muffs for something else. Right after I bought my Borla XR1 there was a dam Corsa muffler on LS1Tech 2 days later! It wasnt meant to be! :flag: Im happy with my XR1. You can set your exhaust up pretty much however you like it. It will just be built around your muffler. The bends really wont do much for to your performance if anything. When you start pushing high HP numbers is when I would start worrying about exhaust bends. But in your case you should be fine.

The Corsa systems give you the best of both worlds - quiet during normal driving with no interior resonance and aggressive when you lay into it. It's like having 2 different systems! Their Sport system has a more aggressive sound than their Touring. Sales are usually split between them.

I had a CORSA Sport and it droned in my Suburban. REAL BAD. Through 2 layers of Xtreme Dynamat plus spray on Dynamat stuff underneath.

 

They swapped it out for a CORSA Touring and it is AWESOME! Actually need to turn down the radio to hear it.

 

 

Unfortunately, now I can hear the wife complaining from the back.........
