car is stock just a K & N drop in filter i want to put in a complete exhaust do i really need a 2.5 collector for the best gains or would a quality 2.25 system be
a good upgrade. No plans for any cams or bigger upgrades. I did search and learned alot but anyone with experience on this your comments would be appriciated. Thanks! Or would i be better off to leave it all stock as the gains would
not merit the cash spent?

 

sounds like you need to visit the FAQ and SEARCH engines of this board.

Quite correct.

 

Asking the same questions in multiple threads is dumb and warrants a

 

just for you who live here like myself i will try and do a better search and believe me i do read the archives for hours just cant seem to get the right words when searching to get EXACTLY what i need to know thanks for letting me know again that i need to search

 

Go to 2.5, I reckon if you are staying with 2.25 you might as well stay stock. JDM DC 4-1 with 2.5, hi Flow 2.5 cat, Kteller8 2.5 exhaust. No more cost than a 2.25.

 

Well at least you search and read, but I think you need to do it more. You already have a 2.25" exhaust, and it happens to be excellent, and also quiet.

 

i keep thinking i want to get this or that but when it comes down to it the stock drive and feels is still great after two years. just wondered if i would realy get 10 hp more with a full 2.5 exhaust that would be worth it. i know that the shock exhaust is like a cheap aftermarket one

 

Exhaust posts in ITR FAQ are good. https://honda-tech.com/zerothread?id=766629

From experience with my car, I don't think its worth it just for performance, might be if you just want more noise. Either stay stock or do all together Intake, Header, Exhaust and tune it.

 

thanks like always i will probably keep her stock it runs great i would probably F it up anyway

 

You are correct. Adding i/h/e mods without tuning can cause you to run lean, especially at WOT, and damage the pistons over time. Many exhausts won't deliver the 10hp without good tuning, and you're talking a lot of money. Stock R is really damn good car right out of the box!

You might consider putting the cash into track time and/or driving school. The R is great, but there's just nothing like it once you get it on the track.

Keep up reading and searching tho, you will learn a ton from this site!

Congrats on the R and welcome to the club.
