High Quality, Sounds Great

Exhaust is well made and sounds great. The only reason it didn't get 5 stars across the board is the passenger side header gasket provided with the kit basically desintigrated after a day at the track.

Will this fit an automatic 2000 Mustang GT? I have an automatic 2000 GT and by my understanding some off road mid pipes will not fit, but this one does not specify.

O2 extensions or MIL eliminators I'm looking to get an h-pipe for my mustang but i read you need extensions for the rear sensors. Now if i end up buying it and get the MIL eliminators would i still need the extensions?

  • I did not need any extensions on my install which is on a 2000 gt. But the MIL eliminators will add about 6 inches more to the length of your O2 sensor connections.

    Sounds Soo Good

    I just received this h pipe along with my slp lm1 today. And installed in an hourish. Just let me say it sounds so good, Cant say what it sounds just by itself, but with the 2 combined it was that exhaust note that i was looking for. When you down shift it sounds like thunder, not all that rasp you get with a bbk or/x and flowmasters. I switched from bbk or/x to this cause i was sick of the " tin can" sound the two made together. Hope this helps. Oh and fitment was perfect, no exhaust leaks and it doesn't hang low like the bbk x-pipes do.

    Exhaust is well made and sounds great. The only reason it didn't get 5 stars across the board is the passenger side header gasket provided with the kit basically desintigrated after a day at the track. I recommend this exhaust, but if you plan on running some track events, get a replacement gasket from Ford.

    Amazed how good it sounds!

    The install was pretty easy being a 2 piece design. It took a little adjusting to get the angle perfect, again, being 2 piece made it easier. I'm running the JBA Shorty headers, this JBA H pipe and Flowmaster American Thunder system. At start up and idle, it has the perfect balance of loudness and tone. Its a deep tone at idle. Going through the gears, it gets alot louder, and has a mean old school growl to it. If you do not want a raspy, rediculously loud exhaust, like I did, this is the one to get!

    So.....taking off the stock h pipe was kind of hard....and then installing this one ..... Was cake!!! Because its a 2 piece item...it was just a breeze....I am in love with the sound this pipe gives.....very aggressive....the way a true mustang should sound!! Sounds great with borlas xr1 mufflers!! Exotic! Uncommon!! Rare!!!

    Great quality and fitment

    Make sure you have 1/2" drives and U joints, otherwise getting off the stock H pipe just isn't going to happen. When you install this, put antisieze on the factory threads for the studs, and buy new nuts - it doesn't hurt to buy a heavier duty exhaust clamp than what JBA included (my only complaint). Go slow and even when you tighten the exhaust nuts, and know that you have to crush the steel of the H pipe over the collector dome on the driver's side to get a leak free fitment. Well worth the effort, and a great quality piece that fits awesome and doesn't hang low at all.

    JBA Stainless Off-road H pips

    I have one of these on my 2001 Mustang Bullitt. Very nice piece. I like that it's stainless too. I have this H pipe along with a Magnaflow catback and love it. Great quality.

    Very good quality all around!

    They had a sale on it, and I'm quite happy with how good it is. It's all stainless and the quality is really nice. It bolted right up with very little trouble; maybe 1.5 hours or so. The two piece construction makes it pretty straightforward. Make sure you get the passenger side header connection good and tight. I thought it was but had a fairly decent exhaust leak at the flange, so I had to crawl back under and torque them down some more. Don't be afraid to muscle up and make sure you tighten them evenly or it will try to cock sideways. I have it paired with regular Magnaflow mufflers (not the Magnapacks), and it sounds REALLY nice. Not too loud at idle, but thumps really good when you're on it. It might be a smidge loud for me (I'm 36 not 16), so I got some Pypes M80's to weld in the H-pipe. The only knock is that the 4 rear bolts where it connects to the mufflers are SHORT. They need to be like 1-2" longer. I had to use some longer bolts which I fortunately had around. I was able to use one of the supplied ones on each muffler connection, but it barely grabbed. If they supplied longer bolts it would've been a perfect 5 stars. Don't hesitate to buy though. It's GREAT!

    Head turner sound

    Fit and finish was amazing, sounds great, its got a nice deep rumble to it. Just watch out for the passenger side header flange nut, what a pain to get off, other than that easy install.
