Once those of us that are not doing the FI thing have added every bolt on possible the HFCs are the last possible legal HP adder worth the cost. Along with a tune I'll be just about done....yea right.

Any low end torque you might lose and I doubt if it would be substantial can be regained by doing a quality tune. Wouldn't it be nice if we all had the same emissions standards as Florida? Laws or rules, what's that? lol

I think you meant test pipes. Theres no smell from HFC's.



The car will compensate for the conditions. It learns itself. Thats why you reset the ecu when you put on every new mod. I also am getting it tuned when i find a shop to work with my chip. Headers and cats are the most restrictive parts of the exhaust. You wont really lose low end torque with hfc's. I really dont feel a difference but i have a lightened flywheel so it revs quick.

 

I have hfc's on my car and I can smell the unburnt gas, but I also have generic hfc so that might make a difference..

 

that makes sense thanks !!

 

Thanks everyone. Sounds like with a good tune much low end torque won't be lost. Should I pair the HFC with a Y pipe or just stick with the HFC?

 

ART pipes!! but emissions... bummer. berks hfc's.
