Borla or Corsa mufflers?

Depends. Do you need the noise to introduce yourself and if so, how much are you willing to spend on that pleasure? Unfortunately, my combination of LT headers, higher flow cat and Borla cat back is too noisy for the wife and myself so if I had to do it again, I'd go Corsa in hope of a quieter system.

Definitely but from what I am reading, Corsa seems to be able to flow as much WITHOUT as much noise which is what I would want. Unfortunately, I have too much invested in the Borla and don't really want to spend more money unless some killer deal comes along where someone has a used set and I can sell my Borla.

I wonder if they have done any tests with a sound meter INSIDE the car and see how much the sound level is with each different system. Obviously a Mustang will be different from a Camaro or a Charger or vette but that is a guide to the engineering.

Catalytic converters technology may have improved. Emissions production and types of emissions may have gone down with the LT1. Or the design of two large size cats instead of two small size and one medium sized cat won over.

All possible. I bought the 91 to transplant my newly built and tuned L98 from the F-body that got wrecked so I didn't really drive it much or bother to look under the hood too thoroughly to notice anything other than where the plug for this, that or the other went to and from.

Headers completely change the tone of any catback system. Including Corsa. The Corsa will still be manageable from the inside, but it definitely doesn't have the same characteristics with factory manifolds and cats.

For what you are wanting go with Corsa. Buy once/Cry once.
I've done them all on my 94' and finally ended up with Corsa. Sounds great. The only other combo I would consider on a stock L98/LT1 would be long tubes into stock LT1 mufflers (also sounds awesome with a small performance boost).

hey all, i have an 86 l98 completely stock at the moment. Planning on getting some exhaust work done. I'm between borla or corsa. So far my understanding is that borla sounds better but corsa has less drone. I want the best possible performance and minimal drone. At the same time i want people heads to turn haha. I want it to sound good but not be overly loud. Good for the street, not for the track if you know what i mean. Thanks in advance for any advice!
