Change in boost when installing a Efini Y Pipe??
 

Greetings all,

I have ordered a Efini Y pipe and I am just curious
about the boost issue. Does it flows a lot better than the stock unit??

Any HP gain in the process???

I am totally sick of the fucking rubber coupling.


Thanks for your feedback

ya, the efini pipe does flow quite a bit better than the old one. ive heard that people usually see about 1lb of boost increase due to the pipes better flow. this can typically lead to around 5 rwhp.

I picked up about 1lb. But the guys at mazda comp said it was good for around 10-15hp. Don't know if it was flywheel or rwhp. CJ
