There really has been no thought given to an axle back system. Sorry.

Lou who did the pipes with the canted o2 sensor bungs? That is a nice way too keep the o2 out of the exhaust stream. I have to say this new system looks pretty sweet, and PPE has some very nice build quality.

There are no shortcuts and the goal is to have a high-quality system with components that will not fail in the long term thus the pricing reflects these components.

Hi Lou,

I also have the same setup. Just got the PPE header installed last week. Car sounds amazing, but it's stinky. Do you know what size is the cat from Magnaflow? 2" or 2.5"? Thank you.

The 2.25" Model. The 2.25" inlet and outlet were stretched to properly fit the 2.5" exhaust piping. It was felt this would give a better seal.

How did you like the PPE header and Borla combo with cats? Did it sound different after you add the cat? Would my car still be stinky after adding it? Sorry for all the questions. Thanks in advance.

^^^^I never had a Borla system, my prior exhaust system was a full dual system with modified stock mufflers. However I was just trying to show you what could be done with the Borla, because the head pipes are the same in size and design.

As far as an odor, no I never had one, because of the cats. I believe that if you put cats on your Borla system, that will eliminate the gasoline odor that your are experiencing.

^^^^Yes! It is my belief that the PPE system should produce equal results if it were catless. However, that's just conjecture. Also, the dynos were run months apart, as I stated in my post on page 3.
