Any one has experience with xo2 exshaust with high flow catalytic converter? Please let me know how it sound and what cat you go for thanks

 

nope not yet but hoping to get the hfc's installed with my x02 within the next month.

 

what brand are you after?

 

ho do you like your xo2? Are they noisy?Don't mind noise but it must be low but not high pitch...

 

i have the x02 and it sounds great, sounds even better after a month of drivin around with it, and yes, its an aggressive low tone

 

No one with high flow cat?

 

I have the xo2 with helix test pipes(straight pipes). I love it. It is deep at idle but it will get to a higher pitch the throughout the rpms. It's not high pitched like the nismo or turbo xs exhaust.

 

I have the authentic hks and aps test pipes, it has a very low aggressive tone, and is decently quiet in the lower rpms. Loud on WOT, and no rasp after about 5min of warm up.

 

I was just getting ready to ask the very same question presented in this post. I have the XO2 and am looking to purchase HFC before a vortech sc install. The problem is I don't know if I could stand my exhaust any louder. I really like the very deep aggressive tone, but it is at the upper limit of what I would ever want. Come on now, I know we've got some XO2 people with some HFCs. Not interested in TPs.

I have heard others mention the real HKS hi-power + fast intentions HFC sound nice, but not too loud. I've never heard an HKS in person so I don't know how loud they are compared to the XO2, but from the sound clips I would say XO2 is louder and deeper at least with stock cats.

 

well i had my xo2 exhaust bolted onto my random tech cats... omg i lov the combo. it sounds sooo low tone and agressive.. music to my ears!!

 

How was the fitment? So it's still a deep tone, that's good to know. How much louder? Metal or ceramic??????
-thx

 

metal.. the tone is awsome.. only realy loud when u floor it.... but loud without rasp... great combo.

 

i have some kinetix cats at home just haven't put them on yet

 

i thought you had the Ti-C. did you sell it? how much did you get for it?

 

direct trade with another forum member buddy. =)

 

What luck?
