Got's a quick question. Yesterday I got a SI/DO Original 40 Series Flowmaster thrown on my beater and I was wondering if there is some break in time. It is not as loud as I wanted it to be. Right now I am running shorty headers with a high flow cat. Thanks
I will never understand how, but they do have a break in. I have a SI/DO on my '95 and after a couple months it got a bit louder. It seems impossible, but it does happen. It won't be alot louder, but it will be noticable.
It seems that anybody who's had a FM will say they break in and get louder, and the rest of the people who haven't had a FM will say they can't get louder.
