Here are a couple of comparison shots of PPE's new catted headers for the RCF. We will hopefully have some test information to follow. Stay tuned.

Ooh those are nice. Wish they were available when I order my EL headers. I still have the extra weld-in cats sitting in my basement, never got them installed.

 

Those are sweet. I would bet that they sound incredible with that engine.

 

Can’t wait for these. Does PPE in Tempe still do installs?

 

They look great! Will these eliminate the check engine light?

 

That's the goal.

I'd shoot them a call about that. See what they say.

no, I asked a month back and they don’t anymore, but they will give you a referral to a local shop that can.

 

That's a huge collector, so to speak. Biggest 4 into 1 collector I have ever seen. If I recall weren't you selling the G Sport Cats? Is that a G Sport weld in, and what cell count is it? Looks great, and to put the Cat to heat right there is a great idea like stock.

 

These are G-sports and I think Rafi said they are Gen 2 or something. G-sports we have advertised are 300 cell I'm not sure if these have changed.

Any updates on these bad boys?

 

Pretty sure they tested these on the RR blog. Gains weren't super impressive if you ask me.

I believe those catted headers came with 400 cell cats and showed very minimal gains, like 9whp vs catback exhaust only setup. We were waiting for a 300 cell variant since 300 cell showed more promised when welded on to a midpipe instead.

 

This is accurate.

Has anyone tried replacing the 400 cell with 300? I really would like to get this. As it stands price/performance with 400 cell does not work for me. I'm sure it does for many others. It would be paired with my Invidia exhaust. I just don't want it to be so loud and have that smell. Been there with my 01-WS6 and 08 335i.
