I don't know about that Trochoid. Not to question you or anything but from my own experience I've noticed that a complete system seems more responsive and a quicker than no back pressure. I only say this because I've ran straight header for the last week and it just seemed sooo sluggish. I'd floor it and it seemed like the secondaries wouldn't even try to open up. I put the stock manifold back on connecting it to the muffler and it just seems more responsive. It feels like it actually get's up and goes. That's just my experience though and I'm sure it varies.

Rotaries rely on a "scavenging" effect rather than backpressure with exhaust to help draw the exhaust.

Installed the RB StreetPort exhaust this morning....took almost 2hrs...but well worth it. The large SidePex streetport can breathe now!!! (replacing the previous RB single setup).

For those who want QUIET...this is the system for you. Dead quiet at part throttle, crusing, freeway...but as mentioned previously...it has a competely different sound than a single system...it has a crazy sounding deepness to it. With a big ass brapin' lope...it still remains quiet enough to not draw any attention from Glendale, Ca cops...sweet.

ahahah yeah nice Dude!!!
yeah I don't have anyone that can weld.
and this is my first Car.

I have LOTS of friends who are experienced mechanics, I can get parts fairly cheap.
I try to do all the work myself So I can learn, and if I fuck up.
I can learn from my mistakes. "Pardon my french"

So a SP RB exhaust would be the one for me!
Approx how much is it canadian, with shipping?

from anyone who has bought it?
I saw the prices on their site, but It doesn't say last time it was updated.
