yeah i dont post on here too much but i was just wondering what u guys would think what would be the best kinda mods for a 5th gen. i got just an aem intake at the moment but im wondering what kinda exhast what would get me the best hp/cost. what kinda header would be best for good performance i guess just give me what u guys think is best to run to get the most hp out of the engine.
thanks

 

the bigger names and most costly exhausts will be able to give you statistical information... most of the time you will lose back pressure and lose horsepower rather than gain.. so do your homework and SPEND THE MONEY...

i'd suggest thermal... you don't need a grapefruit shooter if you aren't running any forced induction...

 

I have a catback, from Thermal R&D. Everyone really likes the way it sounds, cause it produces a deep steady tone and doesn't sound like a weedeater. Prices range from $400-600 for a complete cat-back, but if you just want a good looking exhuast with a deep sound, you can opt for the axleback system. I have also heard Greddy Evo, and it produces reasonable gains, and sounds fine. Tanabe, sounds too much like a stereotypical import, it's loud and annoying. Apexi's dunk system sounds alright, but can be pretty costly.

 

hm.. for your header question...
4-2-1 header for torque...4-1 header for midrange-highend performance.

basically a track/street question. (racing from stoplight to stoplight, or from 45mph+ hehe)

i have an apex'i world cat back exhaust... nice deep sound, and produced a nice gain. i'd recommend greddy evo though..

i have dc 421 ceramic headers, and they are just dandy :-P

 

There's no bolt in 4-1 header with the exception of the Kamikazee which is a POS for NA motors. If I had to do a header again I would search high and low for a good condition Mugen, and nothing else. For catbacks I also run the WS and I like it but it's for cruising and not power, it may make a few hp but it's not an all out N1 style like the Apex N1 or Tanabe Racing Medallion. Personally I think that just about all bolt ons for the 5th Gen dont mean crap. A DC/N2 header, Apex WS exhaust, and AEM or Iceman intake will ad at most 8-10 hp to the wheels.

 

power is power. plus they make it sound better :fawk:

 

does the n1 have a higher hp gain the greddy evo?

i'm gonna trade in my apex'i ws.. if anyone wants it, leme know :naughty:

 

yes the N1 rates higher than the greddy and imo sounds better
this si what i have found from reseach before i bought my N1

 

I would make it look badass first and then do the engine. The lude isn't gonna be all that much faster with the basic bolt ons so make it look tight then do the engine. my .02

 

Some people would rather have a faster car then a better looking car though....
