[Type R magic]

Don't know which size to get, I heard mixed opinions on this.

Will be mated to oem cat and backbox, only mod I have is K&N Typhoon filter, no plans for anything else like remap, decat or manifold etc.

Just want to replace the restrictive oem one and add little more noise, what you guys recommend?

2005 EP3 Type R.
