will custom exhausts do damage???
 

i have brought an exhaust that was custom made for a galant and it will fit my 99 2.5 v6 galant. it has a single resinator in it and is only half the length of the original, the tip comes out just behind the front tyre, i havnt installed it yet as ive had some people say it will be fine but ive had some people say it will do damage.
any input would be greatly appreciated cheers:)

damage to what?

damage to the motor people have said that it will burn rings out and all sorts because it has been shotened and there is not enough back pressure.

Those people are morons.
