So how did you get the stock flex pipe off?
I havent looked at header/flex on my car lately so I could be wrong but I didnt think they were just bolted on.
So the 2.3's looked like this:
and the 2.0L:
I guess yours is more like this but were the bolts/nuts easily removable (nuts welded on?) Were you able to remove it from under the car, with the header still on?
wonder what, if any, gain there is from the flex pipe...humm. I never wanted to deal with the added noise of an aftermarket header..
