Is this compatible with the Flowmaster catted H-pipe?

  • The Flowmaster American Thunder Cat-Back Exhaust (94-97 GT, Cobra) will not be a direct bolt on with the Flowmaster Catted H-Pipe (94-95 5.0L), item # 18468, (http://www.americanmuscle.com/flowmaster-catted-hpipe-9495gt.html). The Cat-Back Exhaust features 2.5" 16 gauge tubing while the H-Pipe has a 2.25" 16 gauge tubing. These can be installed together with some modifications and welding which we recommended having done professionally.

    95 mustang gt/Flowmasters

    Flowmasters live up to there name. They sound bad@$$. For even more power and sound i would recommend The BBK equal length shorty headers for the 94/95 5.0 with the BBK O/R H-pipe. All those togethor my car sounds bad ass. Its got that dont mess with me low idle tone and screams at high RPM's. Great product easy to install. Will need tow new clamps. The ones they give are cheap and break. But thats no biggy.

    Deep Sound Easy FIT

    Easily installed in only a few hours. Fit is as expected. Requires only a little patience when positioning. This product was installed on a six cylinder and connected via an H-pipe adapter. Sound produced is a deep growl. Very nice.

    Gowls but no scream

    Overall I'm pleased with the product, but not without a few downsides. This has a nice deep tone at idle, and really growls when I give it some punch. It's not head turning loud so it won't break eardrums (or upset neighbors if I come home late), but it isn't a purring kitten either. I'd call it right down the middle loud. Personally I'd like a bit more rumble volume but that's just my taste. Install wasn't too bad, although after installing the mufflers, getting the pipes in the mufflers really tested my patience. Even though the directions state to tighten the clamps on the mufflers, leave them loose enough to wiggle the pipes in before locking everything down tight. Had to adjust and tighten things down again after a test run around the neighborhood, I didn't leave 3/4 of an inch between the pipes and frame, but after that, she sings like a tiger. Thanks again AM, excellent delivery and product as usual. You guys are the best!!

    Well Worth It!

    I ordered this and the pacesetter adapter kit for the v6 and I'm very happy I did! I took these to a shop to have it installed and it took about 2 and a half hrs. Now my v6 has a nice rumble to it ! Thanks American Muscle, you've made me very happy with your fast shipping and excellent customer service!

    So quiet!!!!!!

    I was so surprised how quiet this was I was so upset after reading all the reviews and listining to the sound on you tube . I was praying that there was a break in period but after more research found that to not be true. I had it installed by a pro now I am thinking take it off and sell it but I still loose I am very disappointed and hope to hear from American muscle soon. I have gotten many many things for my 4.6 gt 1997 from your company!

    Flowmaster howling whine

    No sure how I managed it but my American Thunders Cat back if done right can actually release a high pitched whining howl, which I love dearly. The howl used to be higher pitched with stock headers, but since I switched to BBK shorties, its even more pronounced and deeper. Further still I upgraded my cylinder heads and it just gets better. By keeping the RPS low I can sneak by, and then turn it loose, hah, its fun to surprise folks. 1994 GT vert, 4.6 ltr w/04 PI heads, BBK/Edelbrock TB, BBK shorty headers, Steeda CAI under hood, BBK catted x-pipe, Flowmaster American (super 44) Thunder exhaust. Over 279 RWHP dyno'd.

    Sounds mean with an O/R H

    Went from straight pipes after the stock mid pipe to an O/R H pipe and the Flowmaster cat back and it sounds 100 times better. A really mean tone that screams over 3000 rpms but is mellow enough when you stay out of it. This is probably the best setup for your money and the tips sticking out from underneath my black bumper looks awesome. I had a local shop install it all for only $100 and the fit was perfect. I did this and a tune at the same time so the sound difference and the extra pep it has from the mid pipe make it a completely different car. For anyone wondering, cruising at 70 with 3.27 gears with the windows up produces nearly no cabin noise. I've not noticed any drone at all with these mufflers as I've heard others complain of and the tone did get a bit deeper and smoother after the "break in" period.

    PURCHASED THE FLOWMASTER CAT BACK FOR MY 97 GT CONV. ON INSTALLATION FOUND THAT TAILPIPES AND MUFFLERS WERE THE SAME SIZE. HAD TO TAKE TO A MUFFLER SHOP TO HAVE MUFFLERS EXPANDED AND TAILPIPES INSTALLED AT ADDITIONAL COST. WOULD NOT RECOMMEND.

    Great Exhaust "BUT"

    Love the Sound but when installing to my BBK H-pipe the Exhaust was about 3 inch shorter making it where I had to take it to a Exhaust shop to have them rework and add some pipe to make a it fit. over all I give this Exhaust system a 3 Star.
