Fast Intentions!!

I don't know your intentions but I have the Fast Intentions test pipes they are really loud and there is definitely a noticeable torque increase. Only drawback in the smell my car smells like a snowmobile with the fumes it gives off.

Motordyne has some pretty sick catalytic alternates, I couldn't get them for my awd or I would have, they sound really nice

 

I tend to favor the Orange striped tabby!!!

 

You can never go wrong with Sylvester. Tom as first alternate.

 

But on a serious note, I just noticed that you asked the same exact question in another thread you posted. You only need post a thread on the forum once. Posting multiple fines serves no useful purpose, it can be confusing, it spreads your answers out in 2 different places, and worst of all, it makes it more difficult for members who are actually searching for their answers before reposting questions that have been asked/answered over and over again. Clearly you're a new guy so I'm informing you so that you don't continue to make the mistake in the future. And for everyone else's benefit too. No harm done.

As far as HFC, there's tons of reviews and impressions already posted on the forum. Check out what members with different ones have to say about them all. Good luck.
