im going to be going FI soon but im stuck on getting a test pipe or a HFC??? i have read that the burks HFC gives you 89% HP inc compared to the TP they offer and it works out that your loosing like 1.5HP. the reason im thinking of the HFC is i dont want to go through the emmision hasle of switching cat back on then going for emmission then putting TP back on etc... but i do want the HP gains now if i gain 2-3HP less than test pipe if i get the HFC then i wanna get HFC if there is a lot of HP loss then ill go with test pipe what do you guys think anyone have a burks HFC installed?? or does everyone just run TP's?


thanks

 

My experience was less than 100 miles on a high flow cat and it was toast. Just get a test pipe and save the money.

 

Serious what kind of HFC was it? 100miless???

 

Hfc robs power , stick with test pipe

 

I've seen threads / posts from other folks saying that FI kills a HFC. But... I've had a Berk HFC on my car for a few years (and two FI setups) with no issues. Maybe I don't drive mine enough to harm it?

 

Test pipe

 

mmm looks like im getting a test pipe

 

If you're worried about emissions just use an extender when you need to.

 

full downpipe to exhaust inlet delete the need of cat or test pipe

 

whats an extender?
