Flowmaster American Thunder Catback

01LaserRedCobra · January 3rd, 2008, 04:23 AM

I was looking through the summit catalog and came across the american thunder catback and was wondering how it would sound without a mid pipe and without headers on my 01 cobra. Down the road I will eventually put long tubes and o/r H but for now money is tight with insurance and car payment. any sound clips or opinions on any other cat back that would sound good would be great.

Mac ftw. I have a set of mac pro dumps and love them. Great deep note and screams at wot.

Doc8224 · January 3rd, 2008, 05:34 AM

Also how much you wanna spend? For the biggest increase in performance and sound get a mid pipe first. If you don't have to worry about emissions testing get an off road h or off road x or off road prochamber. The O/R mid pipes will give you alot more power than just a cat back and they will increase sound quit a bit.

I'm not sure if I will have to worry about emissions I think a friend of mine can get it passed for me because he used to work at jiffy lube and knows some of the people who work there. I want an o/r H but in my town cops can be a real pain so no telling if one would stop and search under it but how often does that really happen? I think the best sound is long tubes o/r H and flowmasters. I just have to buy in moderation so if i bought that kit and down the road bought an o/r H i could add it? same with the long tubes.

Yea the mustang exhaust setups are ball and socket, they just bolt right in. I realy think you should look into mac, they have the chambered sound like flows only much much better. Here are some clips of the mac. These are with off road x pipes. A mac cat back will set u back about $313. These are mach 1's but they have the same excat motor so yours would sound the same. Mine are dumped and sound amazing I will get a clip 2day and post it up later.

That does sound badass. When I added the o/r H down the road would it just sound deeper instead of the raspy sound? and it's 313 for the catback system or the dumps you got?

That's the right kit?

SWEET2KSTANG · January 3rd, 2008, 09:23 AM

that is the right one for your car.
this is the kit he has: MAC PD2960 MAC PRO-DUMPS™ 2.5 inch System 1996-04 GT / 1996-98 Cobra (IN STOCK) - PD2960 MAC

the pro dumps will work on your car as well if you want it. you can get it cheaper than that too, that was just the first place i thought of to post example. the video should be loaded soon.

Doc8224 · January 3rd, 2008, 09:30 AM

Yea 313 for the cat back kit but I forgot you are cobra. Damn IRS. brenspeed has it for 359 Brenspeed MUSTANG GT EXHAUST SYSTEM SLP LOUD MOUTH MAC PYPES
Lethal has it for 389
Mac 99-01 Cobra 2.5" System with 3.5" Stainless Tips [MAC-TK4699] - $389.50

But the kit you listed is the same thing.

Your car sounds awesome. I'm guessing by keeping with the stock y or x pipe can't remember what the cobra came with. it will just be a little quieter and not as deep or what?

Doc8224 · January 4th, 2008, 05:06 AM

Yea quite a bit quiter. And the fact that I have dumps makes it deeper and louder. But go with the mac cat back you will love it. Then when you can get the mid pipe. x or h is up to you. Hell i would say save a little longer and get the mac prochamber.
