I will be ordering a cat-back exhaust system soon for my 99 Z28. I like the borla, and magnaflow the best. Which one is louder? I am open to other suggestions for cat-back systems.

Borla is adjustable so you will be able to make it louder. A lot of people like the Magnaflow and Hooker. Loudmouth is THE loudest, but the rasp is aa little much sometimes. True duals sound the best.

The loudest catback is NO catback at all.

But the Loudmouth is a good second choice

When I open up my Borla it is loud. I stay on the mid adjustment.

the magnaflow isnt as aggressive as the borla. Duals will prob be the best sounding.
The loudmouth is very raw sounding, but im sure its the loudest catback.

Or GMMG. Its not as loud as LM, but its still loud, with a more refined tone to it

Of the few systems that I have heard in person the Loudmouth is the loudest which is also what I have on my car.

One thing that I have noticed is that it does seem to quiet down after about 700-1000 miles from what I have heard with mine. I have no idea why it sounds quieter but it does.

If you want loud and you want a cat-back then you want the Loudmouth. Personally, I'd go for a true dual, but that's not really a cat-back

loud = Loudmouth (name says it all...)....put that with gutted cats and stock manifolds and I was able to set off alarms before I even go into the parking lot

the best sound though is true duals.....its not as loud but its a better sound

Loudmouth is by far the loudest cat back...and the most annoying. Do a search and see how many are for sale.

That's from the permanent hearing loss...jk

i think the borla sounds good if you put any plate besides the large open one in it.

my friend has the magnaflow and it seems to be smooth & mellow. A certain rpm's, it changes to a blaring sound for a short time(300-400 rpms) then mellows out again. It sounds kinda cool like a 2 stage sound. Most of the guys at moroso run their borla's wide open. it has a menacing sound; raw & intimidating. The corsa cat-back is a pretty good one too. Kinda mellow but it has some ***** to it. I currently have flowmaster cat-back. With headers and no cats, it sounds great. i get compliments all the time.
