    I just installed these on my 08 GT and they look amazing the chrome tips with engraved JBA makes it pop. The note sounds better than stock without sounding like a nascar. you may notice people complaining about drone at low RPM, I must admit there is minor drone at under 2000 rpm in 5th gear for me but havent noticed anything too obnoxious about it. I also should mention i found this kit for under $200 elsewhere and thats why im happy with it. There are better kits for the money on this site but have little to no regrets after installing this axle back kit.

    Buy something better!

    I bought these thinking that the exhaust note would be better than what I had with the stock exhaust note on my 2005 GT. I really never got to hear what the exhaust note would be like for a protracted period of time because I could never stop this axleback exhaust system from rattling! No matter what I did, this exhaust system rattled all the time. I finally took them off and bought a Ford Racing system which bolted right up in less time than what it took with the JBA. The Ford Racing gear fits, sounds better and even though it cost more, it is well worth when compared to the issues with the JBA exhaust.

    Great Product for the price

    I was looking for an exhaust for my 08 GT and heard the sound clip of the JBA. I liked the 4" tips and install took about 20-30 minutes. Great part for the price.

    had to return these

    The tip length from the muffler body to the tip edge was different on each muffler, so no amount of adjusting was going to get these right. The "tone" was very nice, but the "volume" wasn't different enough from stock for me. It took 4 days for JBA to get back to AM and authorize a return even after I sent pictures, before which I could not order something else. I think my call to JBA actually helped so it could have taken even longer without me calling. AM did what they could so I don't blame them. They allowed me to buy something different that I'm much happier with. Shipping from AM was top notch.

    had to have em

    Had the old 3" version on my car for years. Loved the sound but always wished the tips filled the exhaust ports a little better. So these and I had to have them. Same sound, 10x better look!

    These Suck!

    These have the worst drone under light acceleration that I have ever experienced. If you drive in traffic and like having a headache when you arrive at your destination then these are for you but since I now have to spend upwards of $120 to add sound deadening material to my trunk, I wish I would have just spent the extra money on a better product. I also have the same problem as the previous buyer that submitted photos. The driver side fits perfectly while the passenger side is too close to the center and points slightly downward. We did every adjustment possible from adjusting the H-Pipe to adding washers and nothing helped.You can see that the tip is slightly crooked from looking down into the exhaust. Very disappointing after spending $330 on a non-refundable product! First & last time I but a JBA product.I will submit pics for comparison.

    Awesome at Idle

    I was looking for something more than a stock GT exhaust but not muffler deletes. These have a great sound at idle, are pretty quiet at 70 MPH, but let everyone know you are here at WOT. They do have some drone when you are under a load with a light foot. I would recommend these to those not looking for the loudest mufflers they can buy.

    JBA's 4 inch

    i've alwyas been a fan of JBA's but never like the tips of them, now that they made 4inch's there sick. installed them in my auto shop class today and even though there not broken in yet they sound amazing. Im going to be honest i thought they would be louder but what can i expect with only getting axel backs with stock catted h pipe and stock headers. anyways im really happy with them it give the car the old 70's mustang growl. Installation wise the drivers side went on in 10 min and the passenger side gave me some problems. i turns out in the directions your supose to detach the exhaust from the h-pipe and when i first saw it i said no need but i was rong. FOLOW THE DIRECTIONS. Great buy for the price!!!!
