Exhaust Size. 2.25" or 2.5"? Pictures up!
Hey guys,
So I decided to get a custom catback exhaust. My question is, what size exhaust should I get? 2.25 or 2.5"?
Also, Lukey or Magnaflow exhaust?
Cheers

I have a 2.5" which is really overkill for the RRM Dp as that looks to be 2.25" OD.
In the upper revs say 4k plus I could tell a difference over stock. The slowness in 3rd gear and 4th gear in these upper ranges seemed to benefit from the larger over stock.
I went with Magnaflow and it was better than the Ebay muffler I had before although still not ideal in my opinion. I think running catless will get you an undesired affect to noise irregardless to what muffler/resonator you are using.

This Saturday I get a 2.25 inch Cat back system which includes a Berklee straight through performance muffler. I have an auto and will keep the car N/A.

3" is perfectly fine on an NA motor so long as it has a large displacement. Ralliart models have a 2.4L motor correct? I know on 240sx's with our 2.4L four bangers, we make more power and torque across the board with 3" exhausts. That whole 2.5" max diameter piping on NA 4 bangers does not apply to large displacement 4 cylinder motors.
What works on a 1.6L and 1.8L honda motor doesn't apply to 2.4L motors.

The shop recommends 2" exhaust, otherwise I'll lose alot of low end torque. They said "Do you want top end performance or driveability?"
Top end 2.25" - 2.5"
Driveability 2.0" - low-mid-high
Do you think I should go 2 or 2.25?
I won't go 2.5 or larger..

2.5" is as large as you should go. It will also make great power when you turbo too, or add more mods.
Stock is 2" so I think that is silly. 2.25" is a great size as there is already lots of premade parts in this size from Magnaflow. Although I prefer the 2.5" if you are going custom.
I mean really there are Lancer 2.0 guys with a 2.5" system with no adverse affects. The Ralliart will suck it up and blow it out either way!

2.25 has been the best compromise.
