so i wanna do a custom exhaust o my 2is, is any1 running thier pipes bigger than 2.5? what is the best size to use?

 

do straight pipes all the way back going to way more then the oem but will "sound" good!

 

2.25 is best.. but 2.5 will work too

 

did anyone remove thier resonator or those cats?? and what muffler was used at the end?

 

do some research.. and yes several people have.. i do not have that resonator or the secondary cats

 

If you do a search for "custom exhaust design", you'll find a thread that talks all about this topic.

 

I dont believe anyone has confirmed this as of yet

as far as exhaust goes, for the $$ the Megan Mid Pipes are pretty nice and sound good, and give you some slight weight savings. you can then have a Tanabe, HKS, or any of the axle back exhaust.

If you check out the Megan Mid pipes installed thread and towards the end Caymandive has a pic of the mid pipes. It has an extra pipe that you could run custom pipes off of.

What are you looking to get out of the exhaust? do you want it to be loud?? Most of what you do is going to be for "sound" on this car and for looks

Caymandive has a video clip of his set up so you can hear the Tanabe and Megan Mid pipes on his car to see if that makes you happy?

good luck!

 

Run a 2.25" with a x-pipe. Best design for this car.

 

I have my resonator and secondaries removed. I put magnaflow 4" resonators to help with the drone and I have the 4x9 oval mufflers. Nice deep tone, not ricey at all. I didnt get the final dyno runs yet cuz the shop has been extremely busy. I should have some final numbers in a week or so.
