pics of s.d. headers WITH cat on please

[quadracer960]

anybody have pics i can look at with stock cat still on? And I have heard there are 2 different types to buy, one fitting better. How would i tell the difference? Also, what looks to be the difference between the once that cost like $205 and the other ones costing around $185? I typed in gtp headers and they showed up. Thanks.

What does the stock cat matter when you do headers? You buy a high-flow one to replace it.

The 3" downpipe on the SD headers is much larger than the stock cat pipe. You won't be able to match them up without using a reducer. You're better off saving a little bit longer and getting the money on a high flow 3" cat.
