I have a 04 Silverado with the 4.8 and I'm looking at getting an aftermarket catless y pipe. Preferably one that will just bolt right in to the factory flanges so I could swap as need be. Anyone have any recommendations for Y pipes to look at? Really would like to stay under the $300 mark

 

cant help you on where to get them from but be warry of peoples return policy if you have to return them. i had an issue with rockauto, they sent me a cat that was built wrong and wanted me to pay to return it and to get the replacement part back. after a few weeks of going back and forth about why im responsible for shipping at all they said they would pay to return it and i would just have to pay to ship the new part. then they stopped talking to me and wouldnt tell me about how to get them to pay or anything at all.
