My 2008 Turbo Forester gets new Killer B headers and Group N engine mounts!

I'll do another video going over my 2008 Subaru Forester XT and what I have done to it. In this video I installed a set of Killer B Holy Headers along with their vband uppipe. Since I was dropping the exhaust manifold I figured this would be a really good time to replace the stock engine mounts that have over 135,000 miles on them.
I decided to wrap the headers in DEI Titanium exhaust wrap. Yes KillerB will not warranty the headers if its wrapped. I didn't want to spend $300 and wait 3 weeks to get the headers coated and figured that with the 321 stainless steel construction, the headers will be in good shape for years to come.
So what has changed after the install? Due to the motor mounts there are more vibrations at idle. However, the car feels really good now that the motor is better planted to the subframe. Wish I would have done this sooner.
As for the headers - the exhaust is now a bit louder. Car is more responsive. Boost comes on quicker and the engine just revs more freely. Was well worth the cost of the headers.
In the next few weeks I'll be ordering and installing a set of bigger injectors, TGV deletes, tubro inlet, and finally a bigger turbo.
I did not get sponsored by any of these companies. Everything was bought and installed by me.

Killer B headers make it sound beefy and aggressive! Nice Job!

[@happywrenching]

The headers and milltek exhaust are a great combo! Not obnoxious under normal driving and super aggressive once you punch it.

Thank you for the video, I learned alot. Subcribing boss.

Do you have to take the downpipe off 100% to lift the motor from the transmission adapter plate?

[@alexnegru2220]

It sounds a lot better💦

[@happywrenching]

Agreed!

Is the Header Lower than the oil pan??

[@happywrenching]

They are pretty much at the same level.

I wish I had your mechanical skills.. Here in my country the car shops and mechanics are really bad, they charge you a lot, they don't know what they are doing and they can even damage your car, they lie about the problems in the cars and so on, so I forced to change a new car every 4 or 5 years to avoid to deal with them.. and new cars are getting so expensive and the reliability is a lot worse, so I don't know what to buy next.

[@happywrenching]

I started out changing oil and brakes then slowly progressed from there - nothing special. Now with so much info on KZbin and forums its much easier for someone to learn to work on their car. I do agree that cars are getting more expensive but there are still some reliable cars out there. Good luck!

Buy a Lexus if you can. Toyota Family cars should be much better to work on

I could be wrong, but I think using Heat Wrap on Killer B headers is not recommended and will actually void their warranty.

[@happywrenching]

You are correct, using wrap on these headers will void their warranty. I struggled to decide between keeping the warranty and having heat soaked engine bay vs voiding the warranty and cutting down on heat from the manifold. In the end I figured since killerb made these with a higher quality 321 stainless steel then it should be less susceptible to corrosion and cracking. I also wrapped these with high quality DEI wrap. In the end, the wrap makes a huge impact in controlling heat from the manifold and I feel it was the right move. Time will tell how the headers will hold up.
