I like taking things step by step and that’s why I asked to keep the cats on before the dyno run as they a vbanded and could have been easily removed. for me this was not a case to compare tunes as both cars have different mods. I just wanted to see how bad the cats would hurt me as I use them to help lower the sound on the roads and kill the smell, I really wanted to see a conservative number and its potential. I will be running the car later with an Xpipe and the cats removed but 1st next run I want to see the car with cats and xpipe then 2nd no cats and xpipe...

I've never even hit 500 rwhp N/A.
What tires and wheels are you two running? Weather (DA)?

Both of us have stock rims and tires. Ambient conditions were the same as those posted in my other thread, equating to a 1.00 correction factor or about 0 DA.

I really think with the cats removed and the xpipe i should break the 500 mark oreven past at least i hope lol...., not sure if i want to do the update just yet as im very happy to pull 489 and lell then 2 tq with cats on.

might put you at the 500 mark.
Good stuff guys!
Which X-pipe are you going to use?

Nice numbers, @xtyper.
Quick question, have you ever tried running your current setup with higher octane gas? It would be interesting to see the power difference on your setup if you let the car adapt up with hard driving, on higher octane.
Also, do you have an opinion on what portion of your gains came from the ROW boxes vs. the hard driving? I would imagine both factors contributed to the power increase, I'm just curious as to how much should be apportioned to each of the two contributing factors (ROW's and hard driving prior to dyno).

Presumably you can install it where the 2nd cats are or where the resonator is. The closer to the engine the better. It is supposed to help equalize the exhaust flow. I think the term is scavenging exhaust pulses to better equalize the exhaust flow from the left and right bank of the engine.
