Thanks for any input, this isn't going to be a debate thread on RTP vs HFC or anything like that. I just installed a Tanabe Medalion on my 08 G35 and it just flat out isn't loud enough. I have done quite a bit of research on the HFC vs RTP debate before buying the Tanabe and I was going to wait until after I installed it to make my final decision. My question is in regards to brands... Some of the brands I have come to are Megan/Beluga/Top Speed, Fast Intentions, Berk, ARK and GTM. So here are some of the questions I have:

Does GTM even exist anymore? I cant find any of their products anywhere.

Are the ARK pipes worth dishing out 700 for?

This site loves FI (and for good reason), is there a discernible difference between Berk and FI?

I have seen quite a few positive reviews here on the Mega/Beluga/Top Speed pipes as well.. I know "you get what you pay for" but can anybody attest to the quality of these pipes?

If I am missing any brands or if you have any other suggestions let me know. The Tanabe is great, but I just flat out want it louder. The reason I am shying away from HFC's is because I don't want to buy them and be disappointed because they aren't what I want them to be, but I am open to suggestions.

 

Here is a clip of tanabe with kinetix hfc. Hope this helps some.

 

Yeah I was creeping on the exhaust sticky and found that, it sounds pretty solid. I am a little hesitant on videos though because my Tanabe sounded louder on video too

 

Oh i know what you mean. I ended up going with vibrant resonators with tanabes. sounds really good. I would go with HFC too if i wasn't in CA

 

Yeah I am in Illinois and they are pretty strict with emissions stuff, but I plan on saving my OEM cats to swap them back in when test time comes around. Our laws are a little more lenient than California lol

 

Also... never thought of tinkering with the resonator. I know they'll help eliminate rasp and idk how much you know but heres a curveball.. what about throwing a pair of vibrant resonators along side some resonated test pipes or pairing them with some HFCs?

 

The HFC would probably sound the best. The test pipes might sound raspy

 

Found this. It's a coupe but he has tanabes with non resonated test pipes
