Get some srt8 exhaust manifolds and you are set! I just installed a complete srt8 exhaust on my 09 and it made a huge difference. Stock exhaust manifolds are pretty restrictive and make some very sharp turns exiting the head. Long tube headers on a mostly stock 5.7 would not be worth it in my opinion. Use a bigger cam, porting,etc and I would say yes but my jeep feels a ton stronger with just a a CAI, Diablosport 93 tune and srt8 exhaust with no resonators..... I will get this thing to the track soon but I expect no problem hitting 13's in the 1/4.... stock HP rating was 357 and I figure over 400 now..... FWIW, 09 heads have the "D" port exhaust that matches the port window shape perfectly for the srt8 headers.... TBF
