What is the loudest size Straight pipe? I've heard 2 1/4 inch straight pipes with 7 inch tips is really loud. Is it? If you have any videos, post them. What about 3"inch straight pipes with a high flow cat and 7 inch tips?
Got a stock 04' with 5.3 vortec. Only mod so far is a K&N air filter. I deleted the stock muffler and put a straight pipe and I get compliments all the time. I think it sounds good. I'll post a video when I can.
