Hey guys, Im new to this forum. Just wondering if anyone knows what HFC brand this is? I just picked them up for $160 today. Gonna install tomorrow. Thanks.

 

I figured someone might know...Ive tried looking up pics for a while. Looks like aam to me.

 

don't look like hfc's to me...looks like resonated test pipes...look inside, do you see cats?

 

I realize that this is a dumb question, but what do cats look like? The pipes look very similar to all hfcs i looked up i.e. stillen, kinetix, aam...

 

berks?!?!

 

The inside of an HFC will have a fine metal mesh.
just google image "inside an hfc"

 

Okay. Thanks. Still nobody seems to recognize these for sure.

 

Look inside and tell us if it looks like this first

Looks like they might be Invidia HFCs, 2nd pic from the top.

nah those have larger resonators to fit the cat comb..these look like the topspeed (ebay test pipes)

^ ding ding ding.....we have a winnaaa
makes more sense with the price he paid too.

 

Does this help? Cat or resonated TP? I honestly dont understand difference, and tried searching...

 

Haha...close, but no cigar! The o2 sensor bung is much different profile on those ebay "downpipes" as well as a crappier looking weld....Im thinking Invida HFcs is the ones that really look identical to me.

Also, it would seem crazy (tho not impossible!) for the same person to have MREV installed, STILLEN headers (expensive)....and then a crappy no name brand of TPs...Im just saying, not impossible, just unlikely.

 

how does this not make since...that picture is a resonated test pipe.

This is an HFC = high flow CAT

what your looking at here is a cat

 

i don't know what your talking about but those are the pipes you have top speeds also sells the same ones for more
