Hey guys,
I'm looking for some advice on an exhaust modification. I have a 98 K1500 with the 5.7L. I found a guy who is parting out a truck and it has 3" exhaust all the way from the headers (no cats) into 2 magnaflow mufflers. I want to keep my cats but I'm thinking if I buy this setup off of him I could cut it and weld the 3" pipes to that flange just after the cats. Right now I'm pretty sure my exhaust is the 1 7/8" pipe, what are your thoughts on the size change? Would this have a negative effect on my system or since it's far enough back would it not matter? I'm new to this so I would be getting someone else to do it, I just want to know if it's worth buying the exhaust or not. Any advice is helpful.
Thanks,
Jeff
