I like the looks of the hks dual, so I was deciding between hks dual with hfc, or just the agency power single. I heard the agency is loud, but how loud is it compared to the hks dual WITH hfc? If the hks dual with hfc is as loud as the agency, I would rather get the hks. But looking for louder between the two. Please help, thanks. Also, youtube clips dont help judge how much louder each one is over the other.

 

Spring will arrive in a couple of months. Plenty of opportunities for local Z meets. I recommend that you listen to similar set-ups before buying.

 

Deciding between these two also.

 

One is heavy and sounds like a Cesna , the other is light and sounds great. Easy choice.

HKS = too much rasp for me. Looks good though.

 

lol. Tnx for the input guys, but still wondering which setup would be louder.

 

Coming from a guy with the Agency Power... AP > HKS... really loud hence the 3" piping and no resonator whereas HKS has dual small piping and two resonators. HKS sounds better with HFCs or TPs (preferably resonated TPs). The Agency is hot but it just depends on what you're going for. If you want race car loud and aggressive tone all the time look no further. Also, hands down the best looking single exit especially with the bumper tuck. If you decide you want one I'll sell you mine since I have other plans for my car.

 

i had agency powr on my tc and it sounded like an animal, i can only imagine what it sounds lke on a 350z

 

agency power will be louder for sure, and definitely will sound better

but i think the exhaust looks racer-boy..

 

hmm just watched a youtube vid of HKS then Agency power and i can def tell a HUGE diff. Search more kiddo

Merry Christmas!

 

For those of you with hks dual and hfc's, is it loud enough to set off alarms in parking structures? I read in one of the threads that a guy with hks dual could not set off any car alarms, so if hfc with hks can set off car alarms, then I know how much louder it actually is. Sorry but helps me compare.

 

OMG. Im gonna go on a limb here and say ur idk 19?

haha i knew iv seen ur screenname before asking other DA questions

 

I have the injen exhaust true dual track edition. With test pipes, rather not say what kind , and let me tell you its ridiciously loud. I can't even hear myself inside my car. It makes people turn around when im just driving normal, people tell me it sounds like a v8 and I love it. Went to the mall today and like 10 cars alarms went off. My setup is pretty rare haven't really seen anyone with the same exact setup. My friend has the hks with hfc and its not as loud as mine.
