I think the problem with any modern car is that decades down the road you will not be able to get spare parts anymore. Try getting spare parts for a 20 year old PC, and you'll see the problem. No one is going to be making the chips, screens and other electronics anymore, and unlike cars from the 60's or 70's, there won't be anyone able to fabricate parts for you, because the stuff is incredibly complex and proprietary.Well I guess in that instance, if it is kept in excellent condition and low miles, decades down the road it could be worth money.
A lower-restriction air filter can't possibly hurt low-rpm power. Lower-resriction exhaust systems CAN hurt low-end power, but he says he plans to keep his.Be careful what you are doing here. The benefits of lower restriction exhaust and induction systems usually occur in the higher rpm range. Great for race cars but not so much for street cars as you risk the loss of low end torque. The people who sell this stuff don't lie but they don't tell the whole story either.
If you don't believe that, take a look at dyno comparisons and see what happens to engine power in the low end areas where you live. Don't get sucked in to believing that noise and drama is usable power.
Just a word from an old hot rod gear head.
I had 3.06 in my car and went to 3.55's, what a difference! So much quicker off the line, car feels a lot lighter.yes, I know there is no gain in a catback. just looking for a little more sound. I know the corsa has no drone and is not obnoxious. I never thought about gears .
