My car is due for inspection next month and my weld-in flowmasters are getting rust holes in them. So Im looking at some cheap catbacks. (due to wife's cancer treatments)

The FRPP C/B is pretty cheap, and I do want something a little quieter then flows with my o/r h-pipe also.

Ive been reading some theads on the web about the c/b, and have a few questions.

1. How hard to install?
I read somewhere that it is 1 peice per side and its a a pain to install.

2. Would it sound good with an o/r h-pipe?

3. I know its a 2 1/2 pipe, but are the mufflers 2 1/2 also?
I saw a pic of the system and it looked like smaller inlets/outlets on the mufflers.

Thanks :SNSign:

I know during inspection they look for little things like that
to fail you but, it all depends on who the inspector is. I never
heard of Flowmaster mufflers rusting that bad to where they
had rust holes in them? You must drive your car through alot of water?
Installing a catback exhaust is pretty easy it can be done with
simple hand tools but, air tools make the job alot easier though.
I know about the FRPP catback but,I never heard it in person so,
I honestly couldn't tell you what it sounds like? I do know the mufflers
are 2 1/2" and the piping is 2 1/2" also.The best subjestion I can give
you is if you are looking for a catback that is not as loud as the Flow's
and a O/R H pipe look into the Dynomax super turbo catback.It is more
money but, it flows better than the chambered Flowmaster mufflers and
will probably give you the sound you want.
The only catbacks or mufflers I hear alot that has bad rusting issues is
the Mac catback and mufflers so, I would stay far away from Mac.
I hope your wife gets better.

The flows were on my car when I bought it. Its rusting around the weld bead.
Who knows how old they are, could have been on since 1997.

I had the same issue with my flows, thats why they got replaced. I wouldnt imagine that the FRPP catback would be hard to install, especially since its made by the people who make the car! I'm not sure about how it sounds, but if you're just trying to pass inspection, and especially w/ the situation youre in, just go for what the budget allows. I hope your wife gets well soon. good luck!

thats a bummer. yea flows always seem to rust faster than anything else. had the same problem on my other stang. you should search for some cheap used mufflers or something. sorry to hear about the wife. hope all goes well.

Does anybody know if they are a one piece design like Ive heard? Seems like that would be a major PITA to install if that were true.
Most C/B's have a connection over the axle, Im hoping the FRPP does also.

I figured for the money right now this will be my best choice. If I dont like the sound I can always weld in some different mufflers down the road.


Thanks for all the get-well's for my wife..
It has been a rough year.

Well, instead of getting new catback, u could prolly just buy 2 flowmaster muffler cheaper then that of catback. If you want it to be quite, i would suggest Magnaflow tho

I thought about that also. But when I was under the car looking at the mufflers, I saw a bad patch job on the right side tailpipe too...
So Im gonna replace the whole C/B, for 269.99 you cant beat that.

That way 80% of my exhuast will be new, I just installed the o/r hpipe about 4 months ago. Maybe I'll save up for some shorties next, who knows..

My flowmasters rusted on the top and I could actually fit my hand in the top of them. Not good at all

I have some take-off mufflers from a mustang bullitt that could help you pass inspection possibly

So yes it comes in 2 pieces per side, not the typical 3 pieces of other catbacks, and it is more difficult to install because that long piece which includes the muffler and axle tube is welded as one piece. The second piece is the tip. I ended up removing the lower shock bolt one at at time, to give me more working room, so once I figured that out, it went easy.

The Stainless pipes are 2.5" mandrel bent, and much better looking than the pinched stocker on there. The mufflers are SS, but they are welded to the pipes on the inside, so the inlet/outlet has to be less than 2.5". If I get a good deal on either a pair of steeda mufflers (made by borla), or Bassani, I might replace them just so I would have 2.5" all the way back.

Overall they have a nice tone once broken in and have had many compliments on the sound.

LI98GTStang, Thanks for the reply.

So it is a 2 peice design, thats what I was afraid of..

So is it a job I can do in my driveway with jackstands?
How hard was it to get over the rearend?

Thanks again...

u'll prolly need to unbolt lower shock bolt from axle.
Be sure to do one side at the time. Basicaly, you place jackstand under frame, with car as high as you can jack it up. and with floorjack pushing up on corner of axle, undo the bolt. And slowly lower floorjack. it'll lower like may be and inch or 2, which gave me enough to remove over axle pipe of my old magnaflow catback. If you have access to lift, u wont have to do this. But most of us don't have access to lift without paying for it

What he said. I put on the catback in my garage by myself, so it wasn't too bad. Removing the lower shock bolt, disconnecting the shock from the axle was the trick.

Thanks alot guys for all the info.....

I got till the end of August, So I'll be doing this pretty soon. My son is 15 and really getting into cars, so I'll have a helper.

Im good with cars, its just good to know what your in for on a new project. I was worried about getting the pipe over the rear-end but you guys easied my mind.

Ive done some research on the FRPP c/b and seen nothing but good reviews on it. Its weird that more people don't use this system.
And you can't beat the price!

Thanks agian Mity2 and LI98GTStang!
