no. you asked for the BEST combination.

 

you won't see much of a difference between different i/h/e combos. if you buy the most expensive brand name ones, you'll probably get better fitment, but if you're lucky, you could get the exact same results with stuff off of ebay

 

not true. you want as little backpressure as possible but you also want air velocity.

heres how caleb explained it when i first joined the site. take three things, a coffee straw, a big mcdonalds straw, and a paper towel roll. blow all the air you can through all three and see how long you can keep the pressure up. its easiest to do through the mcdonalds straw isnt it? the coffee straw is like your stock exhaust...its narrow and constricting. the paper towel roll is like too big of an exhaust, sure its easy to blow through, but you cant sustain it and overall its harder. the mcdonalds straw is like the proper size exhaust. free-flowing but able to keep velocity of the air.

 

the OEM cat makes sure nothing is free flowing...

 

if you gut it it does

 

yeah with backrpessure u need to find a balance between no restriction and a little bit of backpressure. Read Sac's sticky at the top of the IHE topic to read more. Greddy Evo 2, AEM V2, and DC Sporst 4-2-1. Althoguh yeah, basically any DC/Injen/Skunk/Megan/Magnaflow/AEM combination will be about the same. GL


EDIT: Can't forget the Magnaflow High-Flow Cat

 

or jus make your own custom exhaust. Thats what i did. Have my own cust 2.5' exhaust and it cost me less than megan/skunk or whoever and i'm getting the same results as them and if not then better. Go custom on the exhaust, saves money and performance is still there

 

I already have a Tanabe exhaust... Is there anyway I can build it up from there?

 

Cold Air Intake, DC Sporst 4-2-1 Header, Magnaflow High-Flow Cat, but thats about it for building up your I/H/E

I guess you get an artermarket intake manifold and throttle body to help with the intake too.

 

just curious but how would an aftermarket throttle body benefit?
