If I have new ram intake, exhaust manifold, and header installed on my 99 auto Civic EX, will it hurt motor?

Question

That is having all these bolt on mods installed on the stock motor of my auto ex civic with 90,000 miles on it be too much stress on the motor? Will it have to be like dyno tuned if i want to do all of this?

Or will it be ok on the motor?

Also, can I have all these installed without having a new catback exhaust put on it and just stick with the stock exhaust?

Please only answer if you have experience with all of these mods thanks

Answer 1

the motor should be fine, but you might want to change out the exhaust  while you are making the changes, you will get better performance
