Hi, I have a 2000 Lancer 1.8l and I am putting extractors and sports exhuast on it. Just wondering if it is worth putting a high flow cat on or not A High Flow Cat will cost 285 dollars. I am not to worried about the price just is it going to do any difference to the car

Cheers

 

Yeah it will make a difference but nothing huge. As they say every little bit helps. I would be looking for a good quality cat as the cheaper ones can often cost you down the track. All in all the cat is not going to do a lot in the Lancer.
