DB Killer Question

[Petepuck]

Good day,

I'm looking for some info on,

"Does a 6" DB killer restrict enough air to act as a Cat?  If the ECU has certain variances of adjusting fuel/air depending on altitude, temp etc.

Would it not restrict enough airflow to not need a Flash or PC V?

I'm plan to run a OEM chopped header with M4 Slip on, stock filter.

My reasoning is I once had a GPR Homologated Slip-on  with front and rear DB killer. They stated it did not need a different fuel map if both were used

If someone has some info on this I would greatly appreciate.

I am no superstar mechanic and limited knowledge on this stuff.

Don't beat me up if this has already been discussed but perhaps lead to me the stream!!!

Cheers

Why bother with a slip on if your going to restrict the exhaust flow with a DB killer

So it doesn’t sound like a sewing machine, and  shedding the weight of a small cow by removing cat ?

I bought a scorpion serket taper. You cut cat off (leaving headers) and replace with link pipe and can. They say no remapping needed even without dB killer, although I use one in mine, throaty but not annoying noisy.  You retain the sensor in headers so I think ? that adjusts fuelling. Not sure about M4 exhaust though.

Exactly.

I just might end up going that route. The wait time threw me off. Will be snow on the ground by the time it gets here. Was it you that posted a video on YT.?  Your baby cow statement stuck in my head.

Not mine, I saw a video after I fitted mine, the ‘baby cow’ comment made me laugh as it sums it up pretty well !  Quite a few on this forum have fitted the scorpion, I’m very pleased with mine, you have 3 options of can finish, carbon, brushed and shiny. You keep the headers saving money on an unnecessary full system, which is nice....
