How Much? How Much HP & TQ will this add I already have true dual flowmaster, but stock headers at the moment.

Robinson

  • Will add about 25hp and 15tq with a included mid pipe. Make sure you purchase a 'shorty' mid pipe for the longtube headers.

Will these long tube headers hook up to the pypes catback true dual system without modifications?

Dangerous

  • No, the installation of the MAC Ceramic Long Tube Headers (99-00 V6) will require some sort of modification as none of the true dual exhaust systems we have accommodate for long tube headers.

    Amazing buy for a v6!

    So my mid pipe cracked my stock headers. why not upgrade to long tubes right?! well after getting these put in along with an h pipe and a side exit exhaust, my lil v6 runs with the gt's! so much faster and meaner! A must have and the price isnt hurting your wallet! only one problem with these, i have a 2000, but my engine may be a 2001. i dont have the lines for the 2 holes on these headers. NOT O2 SENSOR HOLES, whatever it is closest to the studs on the block. i plugged those though and it works like its supposed to! (Whats my driving style only gives me one option! This is my daily, my show car and my strip car)

    HUGE DIFFERENCE!

    Before I bought this, I had a dual exhaust with flowmaster 40s, and I thought that sounded pretty good. I paired these headers with the off road h-pipe, and boy was I surprised. The difference was gigantic. It sounds like a gt at idle, and stays aggressive throughout the rpms. Last but not least, it made it much louder as well. I get lots of compliments on it and gt mustangs always want to race me because they think it's a gt. I would definitely recommend this part paired with the off road h-pipe if you want a drastic change. It was well worth it even though the total price was around 1,000.

    Awesome headers!

    These make your stang sooo loud and give it a lot more room to breath. Negatives are rattles it gives te car(which can be expected in an old American car), and how careful you have to be about bottoming out... Overall is an amazing product! My exhaust set up is these headers, custom h-pipe with cats still on, and dumped super 40s. Sounds really good(and loud) an won't get ricey until around 5000 rpms

    Mac headers

    The Mac headers are good they made my car move better and sound better. I think the v6 headers sound be a little cheaper but it's still worth it.

    Overall good.

    If you wanna change the sound of your v6 these headers are a must. Also the performance gains are well worth it. Only cons I'd give these bad boys are that the passenger side header was the hardest to install. I think they should hit the designe table one more time and adjust the bends just a little. Only because it was a pain to instal. I actually had to have a buddy pull down on the header piping to bend it to aligne up with the stud wholes on the engine. Over all I give this a 4 1/2 star rating. Just because of the fitment issue. Over all makes your stang so loud and sound like a GT at lower RPM ranges. Higher makes it sound like those v6 stange on YouTube with the off rd exhaust.
