    Limits of stock turbos HP wise

    Thanks for your knowledge with this platform. Do any of the larger exhaust companies make a 3” for this platform? I’m looking at thermal but I want that deep tone as well. I don’t want it to sound like a rice rocket.

    Limits of stock turbos HP wise

    I figured as much due to the EPA cracking down. I guess it’s not like the days of old when catless was the way to go. Thanks!

    Limits of stock turbos HP wise

    When you say the usual downpipes etc…do you mean downpipes, cold air intake, whipple ic…but no fuel system upgrades (no HPFP/ injectors)? Is the AFE GT that good at cooling and moving air that guys are seeing above 500whp? And I agree dragy and drag strip et/mph is the true king but dyno...

    Limits of stock turbos HP wise

    Ok perfect. That makes sense then that limitations of stock turbos is independent of fuel system. And e50 limitations are around 500whp. Anything more than that upgrade fuel system and turbos. Got it. What are we seeing on upgraded turbos and fuel system? Low 600whp and low 11s right? Anything...

    High flow cats Vs cattless downpipes

    Ok great. Thank you guys for the input. Catted downpipes it will be then. What’s the point of selling catless then if people won’t even tune for them?

    Limits of stock turbos HP wise

    Thanks for the info. Are you saying that on e50, you are close to the stock turbo limitations? I’m thinking I’ll knock out the supporting mods now and when I’m ready to go larger turbos, I can just do the hpfp and injectors and be done. I’m coming from an 18 e63s amg where I had pure 1000...

    Limits of stock turbos HP wise

    Question…it may have been answered; I did a quick search and could not find it. I’m thinking about doing a full bolt on build at the moment stock turbos (I may upgrade turbos and do a hpfp and injectors eventually). That being said, what are the stock turbos good for HP wise? Assuming I do...

    High flow cats Vs cattless downpipes

    So I usually ran catless on most of my previous vehicles (850 WHP z06 and 820AWHP e63). I just wasn’t sure what the majority of guys are running. is it safe to assume the majority of guys here run the catted pipes? And Adam at ZFG only tunes for catted? Thanks in advance.

    High flow cats Vs cattless downpipes

    I’ve usually run cattless downpipes in a majority of my past performance vehicles. That being said, are there any performance numbers for high flow cats vs catted down pipes on these vehicles? Is there a huge HP difference between the two, all other things being equal?
