Damn you guys must have sensitive ears lol, I don't mind the rasp over the sound increase compared to stock cats. After looking at the stock cats upon taking them off it's visible that they are really restrictive, to hell with them!

i want them so bad but i cant get them, wont pass inspection, have to get hfc's instead

it won't pass emissions in NY either, but there are enough shops willing to pass you for some extra $

yea in newyork, lol not in va haha

They'll pass in NY as long as you aren't throwing CELs..

Now that Ive driven this setup daily for a few weeks I have a few observations:

1) It is LOUD, I have the 18" resonators + RTPs and it can scare bystanders and eat small children if you open it up. It is just below the threshold of what I would consider "too loud" and I cant imagine ANYONE saying this is too tame. I think the RTPs mostly contribute to the volume.
2) Cold start will wake the neighborhood. It shakes the interior and rattles the trunk plastics, but goes away after a minute.
3) 3 weeks of daily driving and NO CELs...knock on wood.
4) Sound QUALITY is excellent. No rasp at all, little to no drone but VERY agressive. SRM downshifts ROCK! The first few had my girlfriend jump in the seat and ask "what was that!?" haha. Those that compare this exhaust to a Ferrari or other exotics...well...need to have their hearing checked or are basing their experience off youtube clips. It is very deep and can be V8-esque burbly at times, but definetely not an Italian V8 40-valve symphony.

Bottom line...get the Resonated test pipes, you cant go wrong!

Overall...I love it!

Thanks for the testimony. I was looking for someone that had already done the F.I. TDX w/ 18" Resonators and RTPs. Do you have a sound clip in the DB or on some other website?

Does anyone else run this same setup?

I think there are a few other guys running this setup on the forum...most guys run the HFC as opposed to the RTPs though. Here is a real quick clip I made but honestly it does not do the sound justice...you must hear this in person to appreciate:tup:

Idk which part of ny your from but if they can hear you before they can see you, you're f*cked...
I want sound clips though!
Your set up is going to sound badass for sure.:tup:

Nice vid!

I have Berk Test Pipe and I love them. They do have a little bit of rasp when I hit 3000 RPM but after that it clears up.

Thanks to you I just bought FI RTP for my Ark exhaust. Let's see if this holds true.

^ hope you enjoy! Does the ark exhaust have resonators?

I wish my exhaust was louder whenever I get passed by a gallardo or an F430 or something along those lines. I got passed by a Carrera GT with aftermarket exhaust...probably just straight pipes....the other day and I literally wanted to go home and cry.

Any other time, its perfect. I do wonder sometimes how the Stillen would sound with RTP's. Does anyone know where I can find clips of that combination?

Hey. Just got a set of test pipes (non res) with the gtm spec 3 exhaust to go with the gtm stage 2 tt set up. Was wondering if anyone is running the same set up an can tell me how it sounds
