Decat stock vs. aftermarket header (with OpenFlash)? - Toyota GR86, 86, FR-S and Subaru BRZ Forum & Owners Community

Tor · 07-15-2016, 05:56 PM

Would removing the cat of the stock header (hammer/chisel way) be close to the effect of an aftermarket EL Header?

Are there any experience if it's possible to use the OTS OpenFlash EL tunes with a stock decatted header?

Is there a noticeable change to the sound level of the stock header without the cat? (Did anyone come across a sound file of a decatted stock header on stock exhaust?)

Thanks.

I doubt it will be as effective but it will free up some flow as well as make it louder and likely more raspy. I am sure a off the shelf tune would be fine but I always recommend a custom tune anytime anything is changed like that. The plus side is that doing that is cheap as... (insert your mom joke here) and its stealthy

That answered all of my questions. Thanks.

I am seriously considering this route a long with an OpenFlash tablet or a Tactrix cable.

Stealth, cheap and effective!

I saw a used header for approx. 200$ locally. I would might pick that up to use for the experiment and have my original intact.
