SP/SW Header Satisfaction Check:

Those of your running Whipples with the Whipple tune in combination of Stainless Power headers(catted or O/R), are you still happy with them? Using foulers? Any issues?

I'm on the fence to add them while there's a great price on the table. If I get them, I'll be going catted and buying the O/R pipes. Run the O/R pipes 364 days a year and cats for that one special day.

Thanks all!

PS: I've searched the hell out of the forums to make sure I couldn't answer my own questions.

Whipple did not recommend to run o/r not even using foulers, they said I should run highflow cats

I have the Whipple tune using the 02 extensions and no CEL. Don't think their tune uses the rears to calculate anything.

Good point. I knew that had come up somewhere. I'd be fine with just having cats as long as no one has any complaints or has any knock issues.

Thank you sir. Did you relocate your O2 bungs or leave them where they were? And are you using angled extensions?

I left them right where SW put them. Did someone says something somewhere about having knock issues?

Yeah, I can't remember which thread(s) it was, but some people were having issues with hitting an A/C mount bolt and some had some phantom knock, but I don't remember which brands had the issues right now.

they are one of our best sellers. shouldn't have any issues, let me know if we can help out

There were some guys relocating the bungs, but I think that issue is only with e85.

And when we did my SP headers i would've just taken a Dremel to that AC bolt, but it wasn't close enough to bother.

I'm N/A but the SP catless headers have been great and you can't beat that beefcake deal. I had a question mating them to the corsa sport and he called to help...on a Sunday

I just finished installing pypes longtubes o/r, and was told not to worry about the ac bolt,and guess what, it did hit it, its actually a stud with a nut so I was able to saw off the stud part that above the nut from above the engine bay, but if you take off the stock headers , you can easily acces the stud and take a dremel and take care of if,after installing headers its not a easy access. And yes The vibration off the stud hitting the headers would cause false knock

I've been running them with no cats and the angled foulers for a year now. No issues

For the angled foulers, is there a certain position they need to be at? Like, with the with the "L" pointing forward or pointing downstream? Just curious

Sw headers, no fowlers, 7200 miles on the whole setup. No problems yet

My SP headers have been great. I had some clearance between the stud and the header but just dremeled it off for assurance. Everything bolted up perfectly.
