Good evening everyone,
I was wondering what all of your thoughts were on power loss (if any) from the 2.5" bottleneck on the OEM connection point on aftermarket exhaust systems? I have Kooks headers with green cats, a Magnaflow Foose edition Cat back, but it still has the factory sized bottleneck connection. I am running a P1x Procharger at 13 PSI max, and e85 with Lund tune. I guess my question is, would it be beneficial to me to either change the catback for a full 3" design or have an exhaust shop make it 3" all the way through? How much power am I giving up with the bottleneck in place at this power level if any?
Has anyone done before and after dynos or have any other data (1/4 times) or just opinions on the subject? If the consensus is 5 HP gain, then not worth the trouble. If the consensus is 20+ HP, then obviously it is worth addressing. I'm not chasing quarter mile times or lap records. I do however like things to be as efficient as possible and give me all of what I paid for/put into it.
Apologies if this has been answered before, I couldn't really find any solid info on the subject
