Realistic gain from headers and downpipe?
Hey all,
I already have a Tanabe cat-back, and my SRT intake is on the way. How many more HP can I realistically gain from changing headers and downpipe too?
Appreciate any feedback.

Its not a huge difference to be honest. When I dyno with injen intake/ toyomoto headers/ypipe/ greedy catback. Tuned with SAFC II. I had 197rwph.
I mean I could tell a slight difference. Im getting a new set up with mazzuri headers 3inch catback with HKS cam gear II, im hoping I can make 215rwhp.
My buddy make 210rwhp with the mazzuri full set up and SRT intake.
GL let me know if you need to know anything.

Honestly I didnt do a before and after dyno, I had only had injen intake and greddy exhaust.
This would be toyomoto headers and ypipe gen 1.5, I would sell for $225 plus shipping. (They dont make these anymore)
Only 7-8k on these and right now I'm not driving the IS.
edit: the site claims 10-15hp. before after. Yes I do feel a decent difference.
Again I will be posting for sale in 1month on here and my.is
