GTM Test Pipes
But anyways, back to topic.
hey robby, where did ya get em and how much?
i am debating wether to get these or HFC's. But if it doesnt throw a CEL and makes more power ill get these since the G is no longer a daily driver.

How often do you guys in Cali have to deal with tests/inspections?
There's no way I'd pass my yearly inspection with those things on and from what I've heard, Cali is way tougher than MA.
I heard a set of TP's on a G35 sedan this past summer at OCC... sounded great

These will never show the check engine light. You can tell the J-tube is well designed for this purpose. It take like 7 non-foulers to make it that long lmao
Test pipes give more power than HFC for sure, especially on the HR motor.
I'm ordering them on Monday, so there's still a chance to change my mind and get GTM RTP if Robby installed them and post some sound clips, i'm really worried about the rasp/drone if they'll ever make any.
Well TBH if you install the re-designed X and Y pipes I don't think you'll get any rasp/drone.
All my drone and rasp noises vanished with the new pipes so it'll be nice to hear Robby's car once it's installed because he's got the new pipes as well. Also bare in mind that the sound will get slightly deeper (more natural sounding) well that's how my car is sounding now once the new pipes were broken in.
I went over a speed bump today and I scraped the $hit out of the bottom of the car, I had this freakin country and their messed up roads!!!

I hate it when i face 2 choices and both of them are good, so please Robby install those RTP ASAP so i can pull the trigger on those or the Invidia HFC, until now so many people told me to go for RTP, but i'm worried about the sound, i'd kill my self if i had any rasp/drone after installing RTP, since Defratos got HFC and everything is fine, now i need to see how would it go for the RTP.
I was looking at GTM dyno results for their exhaust on the 370z, they got 9.2rwhp and 13.6rwtq on Stock exhaust, then they installed their exhaust and gained a wooping 21.5rwhp and 24.2rwtq, i think their RTP results speak for them selves, all i need now is a good sound clip.

First of all 
In a good way lol
Second, for those who said I will lose power or said HFC will give more gains, slap yourself hahahaha jk lol
This is, hands down, second best mod i've done. Right off that bat my car was taken off like it was on 150 octane
I felt gains all throughout the powerband, the sound is very aggressive and mean. And they look beautiful with all the chrome piping lol
The guys who installed it even said i will get more gains from test pipes than HFC on the HR motor. Tadashi at Technosquare supports this as well.
I am very impressed how it came out. The quality is great and the sound is amazing. Sounds better in person though. I have no rasp at all and no drone. Only below 2,000rpm
I have one sound clip of the first startup but it sounds like these is rasp after 5,000rpm but i confirmed with my friends that there isn't any rasp at all. So i guess after the 150 miles i drive today, i broke them in a bit. So the huge Invidia resonators took away that rasp
I will post up a pic and a vid in a bit
