R2C Intakes … Looking for Input

anyhow i like the top speed test pipe because its cheap and is a quality piece, megan racing also makes a nice test pipe for around the same price($200)
they will add some rasp though unless you get resonated test pipes

i have them and i love the sound, it really opened up my nismo exhaust's sound

ill make a video when it warms up a bit so you can hear what it sounds like

They come with an 8" resonator build right into the downpipe, whether in the TP, or immediately following the 300cell cat of the HFC.

After doing a lot of research of dyno charts and comparisons of HFCs vs TPs, the #'s are right around 1-2 hp higher at the peak for the TPs, but slightly higher in the midrange of the TQ levels of the HFCs, so basically nothing unless you're looking for "bragging rights" on a dyno chart.

IF you're planning to remain NA, I'd recommend HFCs>TPs. Keeps your exhaust sexy sounding with no rasp, and will give you the gains you're looking for.

There are multiple review threads over on myg37, and in the end, the Gen3's came out on top over and over again over the RC2's. The R2C's are more of a sound maker then anything. They do open up more air to the engine, but without a tune you will actually lose power. My buddy ran a before and after dyno with his RC2's and he lost about 7 peak HP and 4 lbs/tq.

The Gen3's on the other hand gain in every aspect of the map. Midrange, and especially at peak. This isn't necessarily a result of "cold air" as so many people get hyped up on, but its a direct result of how the Gen3's are engineered. They lean out the motor, "tricking" the ECU. Is this safe? Some beg to differ, but no one has ever had any issues with their engines from it, only great gains which get even better with a proper tune.

Or **** it, go TT and get the best of everything,

Just a note, some exhausts turn to complete *** on test pipes. MY old HKS and ARK GRiPs responded like hell to berk TPs(maybe the Helmholtz dont like TPs|?). MEanwhile my F.I. CF CBE was just amazing with my RTPs.
