FRPP Headers and 2nd Gen Muffler (now with drive-by video)

I've had the 2nd gen FRPP/Borla muffler for a while. It is significantly louder than the 1st gen (which cracked welds and rotted inside).

FRPP/Borla long tube headers were installed today. They up the ante considerably, with very cool pop and burble on deceleration and VERY loud at WOT. Surprisingly, at steady speeds it seems no louder, just deeper, than stock manifolds/cats/FRPP muffler. No drone at any rpm.

The headers were ceramic-coated by Jet-Hot, which, by the way, voids the Borla warranty.

Will try to get some drive by video soon.

Looks and sounds great!
 
P.S. I blame Sinovac for this.

Sounds great, not so sure your neighbors will agree.
 
I love the long tube headers / Borla combo (my Borla is pretty old). I think the only complaints my neighbors have is the initial "bark" on startup. (Tori modified the tune which made it a bit better).

It is loud at WOT.....
 
No "check engine" light yet. Apparently, this is hit or miss with cat delete. How long before I know I'm in the clear?

Most seem to get it within a few hundred miles. I put about a thousand miles on mine and never got one. Torrie switched off the sensors via SCT as I knew it would eventually become a problem.
 
There is a mechanical device...forget what it is called...that you can insert behind the O2 sensors. Ford stopped supplying is some time ago, but apparently they are still around. Simple plug in device versus a tune.

Mine took about 500 miles, Gary. Running leaded gas got rid of the light.

Keep your tips clean - I followed a "Borla long-tube header/racing muffler" at Miller Motorsports Park back in 2007 (SAAC 32), and in certain corners, flames shot out as he backed off. Mine have blackened quite a bit with the rear exit headers.

They are called MIL eliminators.
 
Sounds great, and looks like the added flow is working as the pressure pushed your camera back when you gave it more throttle. Awesome.

I bought a set of those and was never able to get them to work. CEL kept coming back. Had Torrie turn off my secondary O2 sensors and all is fine.

I'm not completely sure, but they might only work on earlier cars. With the highly developed PCM tuning now available, I don't see a need for them.
 
There is a benefit to using the MIL eliminators vs turning off the o2 sensors. With the sensors off in the tune, the catalyst feedback test never shows ready. With the MIL eliminators, when they work, the PCM is happy that they are working and shows the feedback system as ready.

This shows up during emissions inspection. In Texas, you are allowed one 'Not Ready' code and 0 CEL codes. So with the sensors turned off, you can still pass as long as no other items are not ready. If you do not have emissions testing, suppose it does not matter. The engine is happy either way and it does not effect the tune.

A lot cheaper than buying a tuner, no?

I'm happy with my tune, but I'm sure you can convince me that I'm really unhappy and just don't know it.

Won't work in CA where they put a sniffer up the tailpipe. My nose can tell if the Cats are there, or not.

You mistake me for a Democrat. :lol
 
Can't wait to get my FRPP rear exit headers put on...should be in a few weeks. That sounds nice!
 
Just got my car back from GTG, had their exhaust put on, just drove it from the carrier into the garage, still, what a sound!!!!!
I've had the Borla, and the stock. Can't wait to get it out on the road!!!
 
The expression comes to mind (Blown Away) You had better tie that camera down.:wink
