Hey guys im getting a tune in the near future and was thinking of getting some better upgrades my car is automatic it has pretty much full bolt ons stillen intake filter obx headers, obx catback exhaust magnaflow high flow cat, nwp bop cxj intake spacers i wanted to upgrade my intake pipping. right now its just got the stillen air filter it works great though but i still have the stock pipping would there be a significant difference in gains if i upgrade to a 3.5 inch? And how do i get the materials to do it. Also my friend want so sell me his custom 3 inch exhaust with high flow cat and resonator right now i have the obx 2.5 inch i dont know how much an improvement a 3 inch would be. The only thing i dont have is the nwp throttle body but ive heard a lot of mixed reviews about since its only 5 mm bigger I might pick it up down the road i would like tonknow if any got tuned with similar bolt ons on the auto trans and what put down for numbers

I always love hearing about org members ready to throw down on their 5th.


would you be doing the mods yourself? If so, props to you my fellow member! DIY makes everything more fun! the difference between the 2.5" and 3" would mainly be flow restriction. Naturally the 3" will allow for more volume to easily pass through the system vs the 2.5" system. the 3" cat back system would best be served if a turbo or SC was being used on the system. You're 2.5" system is comparable for now.


intake piping upsizing means MAF upgrades and TB upgrades... you'll find the details here on the org with some minor searching.


Do you desire any suspension or brake upgrades?

I could do some of the stuff myself and forgot to mention suspension and brakes are already done i have mehsn racing strut bar, eibach lowering springs , progress rsb. And brakes i have power stop cross drilled slotted totors with the z26 extreme pads stops great! So yea should i upgrade my intake? Im relly thinking about getting the nwp throttle body..... wonder how gains it would give on a dyno

Headers first, and once you are able to find those, post back.

Mine were sold before I even posted it. Member got wind of me parting out.

So yes, keep an eye out every 5 mins! Its a dirty game when buying 5th gen headers from what I've witnessed with my part out.
