My 1997 CTD is and EGR model that has the EGR deleted. I know that the EGR intake manifold is really restrictive and have heard that the stock non-EGR is better than the EGR. My question is which should I get, a stock non-EGR or spend a little more on an aftermarket such as an AFE bladerunner. Is there going to be a really big difference between replacing my EGR manifold with a non-EGR or with an aftermarket. I am not looking to get huge performance gains or turn it into anything other than a DD so I am not sure if the extra $ on an aftermarket would be worth it.
