  Great product

  Install was a long process but I'm pleased with the overall outcome. I have the pypes x pipe with gt SLP axle backs. Car sounds amazing! Makes a huge difference with performance as well.

  07 Mustang V6 headers

  These headers went on nice but they are not a direct fit especially the driver side coil pack has to be unvaulted it moved up to make the header fit and also the dipstick tube has to be removed but the headers went on nice and easy just a modification to the coil pack they should tell you that when you purchase these headers but they tell you their address fit with no modification there is a modification but with all headers you have to mess with him to get them to work I'm happy with my set thank you

  install sucked, performance good

  so in order to install i had to take off the old headers, remove the 2 bolts that held up the coil pack in order to fit the driver side. To fit the passenger i had to remove two bolts that held up the passenger fuel rail. I also had to move my whole exhaust back a few inches to get the driver side msnifold to fit. it took me about 7 hours to get it all installed. I am by no means a mechanic, but i do know how to work on a car. Idle i hear no difference but i do hear a difference around 2k rpm's. I also paired this install with a sr intake. I completely notice a difference in speed. Since ive installed ive beaten mx5's ,other 4.0's, 4.6's and some honda civics. at least 20hp gains with both install

  Decent Headers, Not an Easy Install

  It took about 14hrs over the course of two days to get these headers installed. Granted a lot of the first day was getting the stock manifolds out and moving the existing catalytic converters and y-pipe back enough to get the new headers in. Once everything was out the oil tube bracket, the metal bracket that holds the ignition coil on the driver's side, and the metal bracket holding the water line and emission lines on the passenger side had to be modified because they get in the way of installing the new BBK headers. Additionally the shape of the new headers does not allow the use of sockets to tighten the retaining bolts in all cases and requires you use hand wrenches. One other note, depending on your existing exhaust, mating it to the new headers takes a bit of effort and may take several rounds of driving and re-torqueing to get it sealed properly. The performance boost is adequate and the sound is a great improvement over the factory manifolds. Overall I am satisfied.

  Solid buy.

  THIS INSTALL TOOK PLACE WITH X-CHARGER EXTREME. Decent headers, beautiful finish, and reputable exhaust manufacturer. I decided to go with these headers, after snapping off a stud in the stock manifolds, while going dual on my 4.0. Rather then drill out the stud I thought it would be a good time to add the headers, along with the duals, and do my tuning all at once. My EGR had to be slightly bent to allow mating on the drivers side. The bracket that holds the dip-stick has to be removed and the header slid over top of the dip-stick and manipulated into place. I chose to do this, rather then remove the dipstick. No problems on that side. Note: with X-Charger the coil pack has been relocated to the passenger side and wasn't an issue. The passenger side, I ran into the same trouble mentioned on the other reviews, not a perfect fit. Leaving 1 bolt out of 3 in the block for the bracket was an effective solution. ( this bolt was left out during the X-Charger install. # The supplied gaskets are good quality, and fitting them was pretty simple. No need to trim excess. Reaching the torque specs is difficult after installation if you just have average tools. I torqued the ones I could,# I believe to 17ft-lbs as stated in my Hanes manual for the stock manifolds) and then tried to apply same arm torque with just by box wrench. No leaks. The folks at AM and Bamachips can address you post install tuning! They make my 4.0 sound bad @&%! The chrome will eventually "blue" due to the high heat temperatures being F/I but im ok with this. Remember, chrome needs to be polished.

  Poor Fitting

  Same problem everyone else had could not put 2 bolt back in due to the flang hitting the bolts. Dirvers side is hitting the back bolt for the Coil bracket the shop offered 2 solutions: 1) The could trim the flang but this required pulling the header back out. 2) Cutting the bracket off so its not in the way and just leave the bolt out. I went with option to since there are several bolts mounting the coil it did not weaken the mount. Suggestion would be to grind the bolt down to the a standard Hex (or just buy a new bolt) and also grind a little off this section of the header to allow the bracket to be mounted correctly. The Passengers side had the same issue with a bracket The bolts head is to big and will need replaced with a standard hex head bolt. The bolt the head is hitting is the one the above the header were the front most pipe comes off the heads. Its a mounting point for a hose which I can't remember what it was for right now (Probably the AC). Have not fully broken in the headers so I can't speak to the color change but its possible it will discolor slightly.

  Nightmare

  So.. I had a shop install mine because of all the rants on here about the hassle with them. Naturally, the shop ran into the same problem.. they just decided not to inform me. I heard the horrible exhaust leak sound that was quaking the street everywhere I drove. When I got home this afternoon I popped the hood and came to find that 3/4 of my gasket on both sides had been burned out and there was a hellish 1/2 inch or so gap all the way around on either side of the head. The mount bolts on either side were the reason for this. They just tried to fasten it as tight as it would go and hoped for the best. Fail. Do yourself a favor, if you get these headers, buy two new mount bolts or shave off the portion that's preventing the headers from seating flush against the head. Good luck! ;)

  Headache but worth it

  I Installed the headers about 2 weeks ago and when i got them i thought they would be pretty easy to install after hearing about my uncles long tube headers on his v-8 but when we put it in his shop we ran into a few problem first problem wasthe egr pipe fitting on the right header, the chrome on the threads made it very difficult, next the bracket on left side holding the water lines for the ac was in the way of the header so we had to cut the on side of the bracket, and then the dip stick what a pain.... but in the end the sound was totally worth it, every where i go i get compliments, car shows, shops, the sore, everywhere people like the deeper v8 rumble the headers give, after a headache with the few inconveniences it was totally worth the buy 5* all the way!

  Not Worth It

  I bought these headers and bbk has made a poor design on these headers. The way the headers bolt on was the worst design ever. Let me tell you why. First off, on the left side you actually have to bend the dipstick out of place and take out a engine bolt just to get the dang thing on. Then the engine bolt wont go back in because the head of the bolt hits the headers. Then after you finally get the bolts on you can't even get a torque wrench in there to torque them down because the dang piping is in front of the bolts. Then on the other side (which is the right side) again you have to take out another engine bolt to get the dang headers on because it hits the head of the bolt. If you buy these headers expect a long install and plan to either buy some new engine mount bolts or to gring the head on the exsiting ones and not being able to use a socket wrench on all the header bolts. And try not to snap the dipstick when your bending it out of the way and then bending it back to mount it back, if you even can. Then the headers turn blue the first day that you drive your car around. All in all, bbk did a poor job in R&D when making these. The performance gains will be the same but spend the extra money and get the JBA headers and skip the hassell. I hope this review helps you out.

  Bolt on performance

  I purchased these headers along with a Pypes brand cat-back dual exhaust kit. Performance gains from this setup has been minimal as far as I can tell, but I'm satisfied. Largest gains seem to be in the 3000-4500 rpm range. Sound is deeper and louder, but I have some drone at cruising speeds. Like Andrew noted, the brackets were interfering with the header flanges on both sides. I choose to eliminate one bolt from each bracket and bend the brackets out of the way rather than modifying the headers. I found this to be an effective and easy solution.

  Not happy like i thought

  I installed them today, well it took me 7-9 last night and 9a.m. to about 8 pm. Took all day because the egr tube (i could be mistaken of the name) was a pain to get off. I removed it with the header as one, used a torch to unbolt the nut, didnt come off. then i soked it in pb blaster for an hour then used three people to take it off. Thats not the worse part, i have to use a table grinder to fit it over some bolt/bracket on both headers. It was really hard to do and just as i thought it sounds like a leak. No sound difference, the only reason i put three stars is the performance. You do feel it but other than that i will never get bbk headers for this mustang again. I have bbk parts and were happy with it so i dont know. Good luck

  California Update

  In response to Eric's review on Dec,7,2009. If you check you're updates BBK has now been approved as a 50 states legal. Great product, love it on my 05 V-6 Pictures to follow in the near future.

  Not Legal in California

  These headers are not legal in California, so that would mean legalizing every smog check, which means more money.
