First, let me say this is the best cat-back I've ever had the pleasure of laying my hands on in terms of quality, appearance, fit-finish, and documentation. Even it's packaging! Able to install in my garage, no lift or without jacks or jack stands. Snapped togother and aligned up perfectly - like leggos.

I had a totally unbiased ear listen for his opinion. When I first purchased the truck and he said it sounds like a explosion - big boom - on startup from his house! Now a lot of that bass tone is gone. Ok, no big deal. It's the on-throttle sound that everyone raves about. So we go on the highway. I can say the motor feels like it is working with less restriction - just about what Corsa claims - 10 or so hp.

Ok, so we make it to the hwy and I nail it. The sound is not what the sound clips sound like and IMO, a lot LESS aggressive than the stock setup. Hmmm, at this point, I'm not really feelin' my new purchase. Then it shifts and I get this horrible tone that echoes toward the rear hatch area. Yep, the "fart" that the stock setup made (that really sounded ok with the stock setup IMO) is now a lot louder. The only thing I can agree with everyone on is the fact that there is no drone and quieter when cruising at speed.

So at this point, I am thinking my stock exhaust will go back on this weekend. The only thing that sucks about that is I will loose my 10 or so hp, and the stock muffler rattle that went away with the Corsa that will obviously return when the stock setup goes back in.

So what do you want for them old slightly used Corsa's??

I think you're going to like the sound of a full Stainless Works exhaust. 1 3/4" Primaries and 3" from the collectors back. ;) I'll post sound clips next week.

You better not make me sell my B&B. ;)

I always thought the Corsa system sounded raspy on Corvettes also, if you want a nice deep tone go with the Borla system.

Any word on how their Jeep SRT8 headers are coming along? I wouldn't mind having a full exhaust w/ headers from SW :)

Wierd, IMO Mopar/Corsa is louder than stock at all RPM's.

It depends on the vehicle. I have Borla on my Mustang and it's raspy, not deep.

I pick it up on Friday. I'll have pics and sound clips up shortly thereafter. :)

This is exactly why Borla does not release sound clips. Please see this explanation (below) from our FAQ's at http://borla.com/faqs/



"Q. Why don't you have sound clips on each of your part numbers?

We really wish we could just package a sound sample in a box like little shampoo bottles or the cologne ads in magazines -- you know, the ones where you pull apart the page and get to actually smell it. But the nature of our product is such that this is not possible.

Although we have posted a few sounds on our website homepage, it's really a disservice to the actual sound quality of our products because they sound so much better in person - no matter what kind of computer speakers you have.

Recorded with a microphone. There are thousands of different microphones available and they all sound different from one another. Record the same system, on the same car, with different microphones and the sound will be different. Variables of condenser mics, dynamic mics, large capsules, small capsules, tubes etc. will all affect the sound you hear on playback. Are you looking to compare microphones or an exhausts?

A compressed sound file - Sound files are normally compressed for web pages and this drastically changes the sound.

Played back through a speaker - Similar to the microphone issue listed in item #1, there are a wide variety of speakers available and they all sound different. The difference in speakers will completely change the sound you hear on playback. Add a subwoofer and it's even less of a true replication of what you will experience after you have installed a Borla on your vehicle.

We wouldn't recommend making your buying decision by listening to sound clips on the web. It's like deciding who has the best tomato sauce by recreating the smell they emit with scratch-and-sniffs. There is no substitute for tasting it.

When you hear an exhaust in person, there are certain physical properties of sound that are impossible to recreate with a sound file, such as vibration through the ground and into your inner ear. The sound you hear from our Corvette exhaust, for example, is not just what comes out of the tailpipe. It's rather a combination of sounds coming from the tailpipe tip, the engine, reflections off the ground, resonance of the cabin -- even the reverberation of sound through your body affects what you hear through your inner ear. You can't recreate all of these variables over the Internet, yet they all affect the sound experience of your exhaust. Therefore, whatever you hear over cyperspace cannot be an accurate replication of what you will hear when you install it on your Vette for real. If you're as critical of sound as we are, this is unacceptable.


Borla Performance strives for opportunities to match up against the competition in real world settings because, after nearly 30 years of success and customer feedback, we have a very good idea of what our customers are looking for.


Although it's fun (and certainly easy) to surf the web and listen to sound clips, we wouldn't recommend using this as your final decision."
