I've got a 2009 R/T and there's an opportunity to purchase a complete 2011 SRT exhaust. From what I have read, everything including the O2 sensors should bolt up. I'd get the factory headers, bigger mids, and 2.75 exhaust (vs 2.5).
Anybody do this mod and what gains did you get?
But the engine you are bolting them to isn't from the 60s and 70s?Looking at the 5.7 manifold, they don't look THAT restrictive when compared to the old V8 "logs" of the 60s and 70s that I've seen.
Care to explain why you think so?Waste of time and effort.
No track times, I have not been to the track.Dtru - do you have any before/after track times or 0-60 with the long tubes? Are you running cats?
Waste of time and effort.
I don't think that is very strong logic. If there is a benefit, then it should be quantifiable on some test. If you're just looking at things on a bench, you have no way to know if one thing is better or not. You are just going off looks at that point.
More flow is not always what you want, you want good scavenging. Unless someone has actual before and after dyno output of this, I still say it's a waste of time. TUNED headers for the 5.7 are a different story with a tuned exhaust for the 5.7 might be worth the $2K plus but unless I was doing other engine work, i doubt I would ever do any exhaust swaps. For the 30hp gains you might get from some exhaust systems, there are better ways to get more power for $2K plus.That's just it, you really don't need to apply much logic as far as "do SRT headers flow as good or better than RT manifolds". It's a no brainier. Almost everybody that has been on this site, almost, at some point or another has seen the dyno results or the differences in 1/4 times with the headers vs manifolds. That being said is the reason why I made the comment, "just look at the two side by side on a bench and you'll be able to tell which flows better. For me not everything has to be backed up by scientific testing and data if it's already out there. Sometimes, and please this isn't dig on you, but sometimes my common sense comes into play.
