I have a 99 Cobra that I want to keep relatively stock. What is the quietest and deepest cat-back that is on the market? Also, can you just remove the cats to make it a little louder than stock and free up some hp?
Thanks.
Thanks.
Quiet.

Steeda has a really quiet cat back. Its Borla but made for them. Get a hi-flow midpipe to free up a few HP and keep it down.

Won't a highflow midpipe make it sound a lot louder?
American Muscle says this product no longer exists.
Buy it from Lethal they have it and yes a high flow mid pipe will make it louder but with the Steeda Catback it will still very very quiet compared to the rest of the catbacks out there. Actually I have found that the stock OE 00R Exhaust is really quiet with a Off Road mid pipe.
I've heard a MRT catted H and Steeda catback on Red Turtles 04 Cobra when he had it, sounded very good. Wasn't very loud, but noticeable.
You could just run an o/r H if you want a little louder sound. I think Steeda and Magnaflow are the "quietest" catbacks you can get.

Just checked steeda's site and yeah..its gone.
I have a friend that had it on his Mach 1 and it was really quiet. That's the only quiet one I know of.
I like it loud so I never bothered looking.
I have the Borla version of that catback with a Magnaflow catted X on mine. It's very quiet at idle but you can hear it pretty well when you get on it. Here's a video comparing the BBK Off-road X and Flowmaster CB that was on it when we bought it against the current Magnaflow/Borla setup. Forgive the Star Wars music at the beginning, my son thought it would be cool.

If you want a deep tone I'd stick with an H pipe, the X on mine gives it a bit higher pitch. Here's a video I found of an 04 Cobra with this CB and an off-road H.

The regular Magnaflow catback is very similar to the quiet Borla, almost an identical design.
I just put a magnaflow catback mine, hardly any louder, just a noticeable difference in tone.
I ran a catted X with the stock catback and the car stayed pretty quiet. I had a pair of Magnaflow mufflers welded in and any noise increase was barely noticable. Those lasted about a week before I swapped them for a Mac catback.
So where do I get the "regular magnaflow"?
I'm assuming they don't sell the "quiet borla" anymore?
Here's the link to them on AmericanMuscle. I'm sure all the major outlets would carry it as well. The default picture they show you is the CB for the GT but there's a thumbnail of the actual Cobra CB you can click on to see exactly what it looks like.

So the Steeda catback on Lethal is basically the old Borla Quiet system?
The Steeda catback is no longer made, and hasn't been for awhile. Lethal is just not up to date.
I believe you, but I just put one in my shopping cart at lethal.com, wierd???
Sweet! So the Magnaflow looks like my clear choice if I want a quiet and just a lil deeper with absolutely NO rasp.
Check the market for a used catback. You can find clean systems for under $300 on here.
I'll try that! It's too bad that the Borla "quiet" system and the Steeda are both no longer made.
It's gonna be either the magnaflow or a used ^^^ system.
