Greetings,


Well I know what you thing but I can't decide between
The bonez high flow or the N-tech high flow cat.

I have already searched but I cant find what I want.

I have a dowpipe, Apex GT cat back, Efini Ypipe and a
ECU on the way.

I am just worry about the N-tech. They say:

"Flows as 96% as a midpipe.."

I don't want to loose all of my low grunt with the N-tech but top end is better for sure with that one.

Anyone got the chance to test the 2 cats?

What a pain. What do you thing ?

Thanks
Serge

 

I had the bonez hi-flow for, ummm...about 3 days before I chucked it for a SS Midpipe...

Hi-Flow Cat --> Dyno'd 285 rwhp/241 rwtq @13.5psi

What's HKS Twin Power?

 

HKS Ignition upgrade

Do you suppose the hp increase was more due to that than the midpipe vs. Cat? that's a healthy power gain!
