It's getting harder to make power out of the tailpipe these days. Props to the OEs for tuning their systems to a higher standard. But there are still a few ponies loose in the corral, and as long as that's the case, tuners will go after them.
We crashed Invidia's R&D party as the company developed its exhaust system for the 350Z. Technicians tested a number of different canisters, resonators and tubing sizes to come up with a workable combination that made the proper impression on the chassis dyno.
The result is more power from the drop of the hammer to redline. There is nearly a 10-hp bump between 6100 and 6200 rpm, with peak output checking in at 8.2 hp. On the torque side, a peak gain of 5.1 lb-ft was realized. Invidia has illustrated that while it may be harder to make power, the payoff is still worth the effort. Working from a 237.4-whp baseline, Invidia technicians sampled different resonators and canisters before coming up with the winning combination that pushed output to 245.6 --an 8.2-whp bump. Torque was up from a 233.5 lb-ft baseline to 238.6. It should be noted the engine was equipped with an Injen intake during baseline and exhaust testing.
