Exhaust

Ok, am starting a new thread on this. I just wanted to know if my 2.25 exhaust will be ok for my turbo set up, or am I going to have to make it bigger. I'm not looking for huge numbers seeing as this is my DD for the next 2 years while im still in school. Any feedback would be good. Also If anyone is selling an HKS exhaust I am very interested.

Thanks all

you are going to need something bigger... how much boost are you looking for? if you only want low boost than 2.5 would be fine... but i can bet you will want more later on... and you will need to go 3inch exhaust then

^^thats what I did with my setup. I'm only running 9 lbs now, but I know I'll want more later so I just did 2.5" downpipe and flex with a 3" flex-back.

But if you have 2.25" now, you can keep it, I'm pretty sure it won't make too much of a difference at like 8 lbs of boost or less.

your 2.25 inch exhaust will work. you dont need to go bigger. but if your running like 10lbs of boost, going from 2.25 to 2.5 would add like 15hp.. with the duratecs, ive heard focussport recommends 2.5 inch with their turbo kits.
