test pipes?
#16
I didn't see a *huge* difference between the crawford hiflows and the test pipes, like Dave mentioned. Likewise, I didn't much of a difference from stock to the crawford cats. And like Dave mentioned, I'm sure I'd see greater gains from a tune.
However, my car should not be taken as any kind of barometer. My car showed almost exactly *half* the gains from the mrev+ than any other posted dyno. And that was in addition to the exhaust at the same time.
I'm not saying that my car magically cuts in half gains from all mods; but my car has not responded nearly as well as a few other revups; thawk408 the prime example.
As for the test pipes - I love them. I've got the kinetix resonated test pipes; there is rasp, but not as much as straight pipes. There is also a fuel odor. There's also a rattle from the passenger side; the pipe isn't in direct contact with the heat shield, but I think the passenger heat shield will resonate at certain times with the exhaust; causing the rattle. The noise comes and goes; it's only under WOT, and it's only occurred a handful of times.
Test pipes, in my case at least, will increase overall vibration in the cabin; I feel greater vibration through the floorboard and pedals. If you want your car to retain factory smoothness; test pipes are *not* for you.
If you want to hear what they sound like on my sedan(plus my exhaust), look at this thread:

Immediately after switching out to TP's this flat spot was gone, as I mentioned, my car would now break loose from a stand still; a first for me with my sticky 275 T1R's.
At the track though, I can hardly chirp a tire, even with temps in the 50s. I do feel that annoying dead spot, but the car still pulls ldecent lower to mid 2.1 60 foots, which feel damn slow thanks to the initial deadspot bog.

As opposed to OEM sized 17's, I'm running 275/30/20 which was [up until I got the TP's] impossible to break out from a launch w/o brake torquing. Hell, I couldn't get them to squeak even with brake torquing before the TP's. Hopefully a couple people that have ridden/driven my car before/after will see this thread and offer their impressions.

Test pipes make power. I can attest to that. But even the resonated WILL rasp and they WILL throw a SES light. Wrap them tight with header wrap to damp the ringing and vibe on the heatshield. Then get a $10 set of no-foulers and your SES light problem is solved.
Expect to be a bit lean with them because like with any breathing enhancement, you won't get the most from them until you add more fuel per a reflash or ECU piggyback.
