I just recently bought a Stainless Works full exhaust system. Before we install them, had to get on the dyno for stock baseline numbers.
After the first pull I snagged the filter off the Lightning so it could breath better. Here is the results. On the 2nd pull he feathered the throttle so it wasnt as straight.
I went ahead and got it dyno tuned from a local guy here in Tulsa. But we used a different dyno. I also ended up not using the 3" over axle pipes or the stainless works chambered race axle backs cause come to find out they only fit the 07-09 GT500's. And NO shop would fab it up for me.
So with LT's, offroad X-pipe, 2.8 Metco pulley, and a better air filter it laid down 540 rwhp and 522 rwtq @ just 10 psi...... Like I said different dyno so hard to compare to the stock dyno sheet. These are also SAE numbers.
