I'd like to know this too. I have the secondary cats and mufflers deleted.
The JoeZ catback exhaust adds about 22rwhp.....Anyone done this yet or plan to do this? I guess first off - does anyone know the gains made from the secondary cat and muffler delete?
Secondly - Im considering doing the cat / muffler delete and adding in the Sikky headers..... I think this would warrant one hell of an exotic sound, but also may be too loud.
Just some thoughts and opinions would be great.![]()
The Secondary Cats have no effect on the CEL. The sensors are located before and after the primaries only. Somehow Sikky must fool the ECM, I'm not sure what they do.With the secondary cats deleted though - would this set off a CEL?
Honestly, In my experience its faster than the JoeZ system. I was the first person to do the Secondary Cat/Muffler delete and have loved it! Ive raced 3 different JoeZ ISFs and have never lost to a single one. Checkout my youtube channel to see how my car runs. Trust me you wont be disappointed in your car when the mods are done. Just compare the JoeZ setup to the stock and you'll see that the power mainly comes from the cat delete.I'm planning on taking my car to a referred shop here in the city to see what they can do for a custom set up. I will definitely let them know I want new piping from front of the second cat all the way back....removing the secondary cats and mufflers. Does anyone forsee power LOSS by doing this? I would assume not since it is free-ing up the flow.....?
I really don't believe a modified stock exhaust is going to be faster and I'm certain the Joez makes a tiny bit more power with the x-pipe. The JoeZ exhaust also sounds less raspy than having the cats and mufflers removed and replaced with straight pipe.Honestly, In my experience its faster than the JoeZ system.

Could be the case.I really don't it's faster and I'm certain the Joez makes a tiny bit more power with the x-pipe and it sounds less raspy than having the cats and mufflers removed. From what I have seen I just believe you drive better than the average "Joe".![]()
i agree wit cayman, i think it all comes down to the driver and Mr Slay u are an experience veteran driver my friend. love ur videosCould be the case.
You won't lose pewer with either setup. Comes down to preference I guess. Can't go wrong with JoeZ IMO.from what I've seen the exhaust is high quality.
