Test Pipe owners chime in
 

Chime in your loves and your hates of your test pipes....keep it breif, just curious

hated the rasp, you might get some fumes. Nonetheless, when I paired it with my otherwise stock exhaust I had good gains and a much better sound.

love: good power
hate: loud and rasp.

No rasp
No Hiss
Fume smell is gone
All the power
No tq loss

GTM TP, just install. Hadn't ran with them yet. Probably loud and raspy. I love that. Adding Greddy TI-C also this weekend.

I'm running the F.I. RTPs. I loud how loud and throaty it is. There is definitely hiss on decel. and the smell of gas when idle or at a stop. Love it though, and wouldn't have it any other way.

I wonder, do the ART pipes resolve the VQ hiss? The hiss I have now is extremely loud but I've come to grips with the fact that its just a characteristic of the VQ.

I have invidia non-resonated test pipes. It is a little raspy but sounds great when combined with a catback. it also adds a little sound if your on a budget or don't want to loud.

Con: Can be a bitch to install.

I forgot about that part, the demon bolt is a real PIA to get off, in my case the exhaust manifold bolt was overtorqued from factory. Nissan did not want to make it easy to drop out the Cats.

Surewin TP, Surewin Y-pipe, Top Speed CBE. Good power with the TP if you can get over the rasp/tin sound at certain rpm's. Some fumes while stopped idling get in. Trying to decide if I want to put the cats back on. Hmm.

I'm switching to resonated TP's soon. The rasp ~2.5K is annoying.

Sounds like a robot farting.

:roflpuke2:

It's gonna be HFC's for me

I'd still try to get a set that is resonated. I think they tend to rasp too.

The ART pipes are basically resonated, so they don't do that.

I had Berk HFC's and swapped them out for CNT RTP's. I havent driven the car very much since the swap but what I can say is that the sound barely changed. No rasp, maybe a touch louder and I did notice a slight fuel smell.

This will be my exact setup after Saturday, I have bought a single Vibrant HFC and will be chopping my Y pipe at the mid pipe flange and adding it in there, see how she goes and sounds.
