3.5 downpipe vs 4

[redsmoke]

How much difference in egts would there be between the two. I have seen where people have said diamond eye 4 inch downpipe fits good but wouldn't do it unless drop some egts.

If you are considering ditching your oe than I would just go right for the 4" and call it done. There won't be any substantial differences in egts between one or the other but definetely won't be any higher goin to a 4" plus you eliminate any adapters and hassles. I went with diamond eye and bought my stainless band clamps from summit and bought my elbow and 3' of flex from 4 state truck when I passed thru Joplin. I have a stack so I didn't have to worry about buyin any tubing. If you're looking for full exhaust, I'm sure you could find a cheap cat back and only worry about a small extension to reach between the dp and the new system.
