I need help. I have a 98 Dodge Ram 1500 4x4 with the 5.2 engine and I wanted to get a glasspack put on it but I dont know what size and all that good crap. Do I just need one with a 3 inch diameter? Anyone know any good brands to get. I dont want to go too expensive I was thinking something like a Purple Horny. Any Advice would be sweet. Thanks
