CA header and XTC DP with high flow cat
 

so i just bought the CA header and the XTC DP with highflow cat. Are these a good combination? i herd they where, but i havent herd anyone on here say they where. Will the high flow cat mess with the post o2? and will this change the tone of my car? I think my next step is the vibrant 3'' cat back. Will this setup run good together?

i have them both, i have the ca header, and the 3" highflow dp....def a different sound, and no ull have no problems

good, so do you like the tone?

yea, its nice...i have a vibrant 3" exhaust too
makes a nice deep tone on the idle

did you need any tuning when you did your exhaust setup?

no, when i got the stage 4 kit it got tuned

CA downpipe looks like crap in my opinon i was not happy with the quality of it. Does it work sure. Well see how long it last. The fitment of the flanges were welded shitty on mine. Would i reccomend it maybe. But id try and find soemthing better.
