Need Advice on improving mid range and top end

Qx_Indulgences · 06-27-2009, 02:07 PM

I have some extra $$ laying around now that its summer and i'm free to work wayyy more hours. I wanna improve the mid-range top end on this beast. WHat would be the best exhaust and intake combo for this? I'm currently running the 07+ pipes and thought about running dual spin tech super pro streets. Any advice would be appreciated. Thanks guys!

I believe JBA shorties will increase your mid/top end (don't jump on me if I'm wrong), after I had mine put on it made a difference in the mid and top end. Also maybe running a little bit bigger pipes like 2.50 inches.

I own/have both the volant and aFe and I kinda think the aFe has more low end but the volant I think may have upper end really trivial. on exhaust larger diameter or duals would be better for mid/upper one pretty common misconception I see thrown around alot is midrange and topend power meaning speedwise. exhaust will control rpm power but not so much speed which is more a side effect of where u make your peak power. so you plan on running your motor into higher revs or get more pull from 40+mph? this is a huge difference imo, more pull overall is on thing that would make a huge impact on pull @ 40+mph. intake exhaust and any handheld will get you quite a bit more pull imo.

so if you want a catback for high rpm I'd say probably the nismo dual setup is a good one. if you want to keep your pipes and just swap mufflers I'd say something that's a flow thru design not a baffled muffler like the spintech. the bullets would be flow thru I think. as well as other glasspacks and the powersticks ( I just ordered me a powerstick

) and as little bending/bends as possible would also be good for either. a JBA catback I'd recommend for more all around pull. this is going by piping diameters and judging from other peoples titans. I understand airflow and can somewhat apply it to exhaust setups so I'm comfortable with those two recommendations. they are also the most popular for a reason. I think the JBA will leave you more cash for an intake and programmer. I'd recommend getting both used so u can get all three instead of just intake and exhaust

I've seen intakes for around $100 and programmers for about $240...

and the JBA can be had for around $400 so for about $700 you should be able to get all 3 or just the nismo catback

really depends on your plans and what you mean by mid/high end power speedwise or rpm high reving power...

Any set of headers, also us 04-06 VK56's can put on an 07+ Intake manifold and with a proper tune can gain top-end...also look into 2.25 b-pipes...I would suggest a flow-through muffler for top-end such as a Magnaflow, Bullet, Borla or the like...HF cats will help...Any intake will pretty much do the same, but I will say, when I got my AEM, the only place I REALLY felt it was on the top-end

you can also do cams if your a 04-06. very sone you will be able to do it for the 07+ also

i had a couple of different setups. i had stock pipes with muffler swap, true duals with 2.25 pipes & last is 2.50 y-pipe to 3" pipe to muffler and i can tell the most difference by far with the 2.50 fm y-pipe. i'm runnin a 3" in/out bullet muffler and afe stage 2 intake. this combo is the best of all 3 i had. decent low end, good mid, and excellent top, for me anyway.
it's hard to say what is the best combo because everyone likes different setups. but this here works perfect for me.
