Subscribed... I wanna hear the soundclips, but I'm not sure how smooth that would go at work.

 

I really like the sound of trix4kidz...that purr when he let's off the gas, but I'd like to hear more soundclips of the berkshire. TrixR4kidz..did you have any check engine light problems?

 

^ +1.

 

Correct Berks won't pass visual check.. I had my smog check last Jan, the guy told me no codes came out, but he heard something weird "the hisst sound" so he checked it visually. He gave me 3days to change it to stock and come back for repeat check. (the guy told me he is just doing his job, he was going to pass me, but that haist sound really noticeable)

you guys think if I change my Y pipe I can eliminate the "hisst sound?"

 

I actually was interested in this too, specifically the FI Resonated HFC's. I know that they're supposed to make it quieter, but is it too quiet? Planned to get the Resonated HFC's first and eventually FI's carbon fiber exhaust. So which do you think I should go with? FI regular HFC's or the resonated HFC's?

 

what does a borla cat back cost ? i wonder if it or any other cat back is actually good for a for hp/tq. i knew on my old bimmer they really didnt do nothin power wise

 

FI cats somehow made more power for me than art pipes on a dynopak. Go figure. This was with full FI exhaust though too. Personally think they make wicked cats and exhausts, mine still dont sound like a shaker instrument.
They might pass smog tests the first year, but after one year of driving i doubt it.

 

sound good guys, man i want my car to sound like this xD

 

really? thats odd. do u have the dynos? i've been thinking about getting md art pipes but if they dont add any performance then ill just stick with the FI hfc and get a tune instead.

 

I had the exact same question. Has any one had any experience with fi resonated hfc's is it really worth the extra 100 bucs for them?

 

I love the Fast Intention exhaust. However I'm still undecided. I might go with HKS HP exhaust. Anyone know what exhaust goes best with the Berk HFC?

 

anyone know when your cats are bad? I get the smell of bad eggs everytime I gas it hard.
