PPE Headers Installed
Well I installed my PPE Headers last night and I must say I am impressed you do feel the car responding better and feeling faster. I am running no cats and the sound is great. There is drone at around 2000rpm but nothing too crazy. I honestly thought this setup might hurt my ears but honestly its a tad louder than my Joe Z exhaust which is loud and sounds great to begin with kudos to Joe. To remedy that issue you can do hi flow cats but it will sacrifice a little performance. At cruising highways speeds like 70-80mph and cruising street speeds like 40-55mph you can bearliy hear it and you can have a conversation in the cabin with no problem. The install was flawless but time consuming around 9 hours. The only problem that arose was the factory secondary O2 sensor attached to my Joe Z exhaust was reading slow and threw a CEL. My installer went and ordered a replacement that should remedy that problem. And of course you have the gas smell in the rear. I will eventually get a dyno and compare the numbers with everyone else with headers. Hopefully i will be running around 400whp. I want to give a thumbs up to Gary from SpeedInjected for making it happen. Looking forward to any questions and/or comments from any other F owners with or without headers.
Thanks
Thanks

Yea i have mine installed now too, no cats atm, and i would agree with everything. it's louder outside the car (when the wife drive away from the house) but inside it's only a tad louder than with the Joe Z only (cept on WOT of course). It's really amazing the difference in power though, the car pulls like a beast and the sound is amazing. It makes the Joe Z exhaust better imo.
The local speed guys who do weekly meets (mostly Stangs/ Vettes and Vipers) said the car sounds like an exotic, heh they all love it too.
Grats Lex, though i'm jealous you got your install cheaper than I did

Update well as I mentioned earlier one of my o2 sensors was reading slow and thus threw a CEL so I was at the shop ready to replace the sensor and solve the problem when the mechanic read that all sensors were reading so what are the changes of that happening? Anyway originally the secondary cat threw the CEL now there all now reading slow. I remember toothdoc had an issue with the wiring melting due to an irresponsible shop. My shop installed everything flawlessly, anyway my mechanic is going to contact Paul and trouble shoot this problem. Any thoughts on this? Bad wiring? O2 conditioner? Blown fuse? So far on the forums from what I see with the exception of one member there has been no CEL issues. Any advice is truly appreciated.

1. I needed to replace both of the sensors aft of the Hi Flow Cat.
2. About 4 months after the install, I needed to install the o2 conditioner due to another CEL.
No issues since then
