Hey ppl
really unsure on what pipe size for a cat back i should put on my ES. Dont really plan on putting any future mods except for changing the air filter. I Just want a little extra power in between the 2-4rpm rev range. By getting a 2.25" will i get a lag in power in the low end?
thanks in advance for your advice guys!

If your breather mods are just gonna be a new air filter, I'd go no bigger than 2.25". Stepping up to 2.5" will seriously drop your low end without accompanying intake mods.

What's the stock piping on the lancer? I have never really gotten that info.

2" OD.

Dyno proven gains at 2.5". I've yet to see a dyno for a 2.25", but I'd still like to see the comparison. Suit yourself.

C'mon Andrew It's 1 7/8" ID. Giving measurements of piping OD is silly especially if you are trying to get an accurate figure for volume. Not that anyone cares about figuring the exhaust volume for a catback anyway. But standard measurements for piping and tubing and hoses is ID.

If you're just putting an intake on the front, I would save some cash and just get an awesome sounding muffler. That will reduce your backpressure enough to get some gains, and a catback won't be all that much better with the rest of the restrictions on the cats, exhaust manifold, intake manifold, and throttle body.

Do you have any idea how lazy I am?

i will most likely end up getting a high flow cat a while after i get the cat back.
do u guys know if i will get a loss in lower end power if i go for a 2.25'? would i even get an increase in power from just a catback exhaust?
If some ppl can let me know how they have went after installing a 2.25" catback that would be great..thnx
