Which HFC is best when running boost? I have ran test pipes with my STS turbo for several years now, but have always disliked the smell. I have always wanted to change out the test pipes for HFC, however I have heard that the HFC break down a lot faster under boost which could possibly destroy the rear mounted turbo. The reason why I was going to change them out now is because I hardly ever run full boost anymore. I hardly ever go WOT, and if I do I have the controller set at 5 psi. So what HFC is the best option for my setup?

 

Turn up the boost n drive the sports car and the FI kit u bought for it the way it was meant to be driven!!

LOL

 

I've done that for 2 years... and then I blew the motor haha. I replaced the motor with another stock one and need this to survive another year until I start working to upgrade the motor, or the car. 10 years of school loans here...

 

Any metal high flow cat will survive FI. Vibrant has low cost options.

 

My FI HFC lasted me 3.5K before I blew them out. The 300-cell metal inside was crushed and became loose. And I was only pushing 11psi on a vortech. FI replaced them and I sold them and bought me some Art tp's. I hardly get any smell with these and love them thus far (5k so far).

I would stay away from any HFC's.

 

My vibrant 200 cell's are going on 30k miles with no signs of issues.
