Anyone with HFC or Test Pipe regrets?

bluestyle55

Guys…
I alreaedy have an Invidia Gemini exhaust and am weighing in the pros / cons of the HFC or test pipes. Berk will probably be the product I select. I have a Stillen G3 (Christmas present ) waiting to be put on and I am trying to convince my self to get the HFC and install them at the same time. I think I am pretty much sold on the idea of a HFC but just looking for some additional peer pressure to make the purchase.


I am a little concerned with the hiss sound. Is it really a big annoyance or not? A simple Yay or Nay would be appretiated.

What about exhaust smell? Is that only an issue with test pipes or does smell increase with HFC? How bad is it with the test pipes?

I am just looking for the feedback on weather people have regrets or was it totally worth it dispite the hiss or smell? Did anyone take off there HFC/test pipes desite of these things?

I remember with my STi, a HFC was nessessary to get a PROPER tune. Now I know the Sti with the turbo is different than the VQ37 but would you say that the tuning potential is much better with the HFC or test pipes?
