I will eventually have all three of these, but i don't have the money for all of them at once. I was wondering if anyone knew where the most gains could be made if I was to purchase just one of these for now. Which part creates the most flow loss?

I know most of you will want to say get the exhaust just because of the better sound, but I will eventually get all three.

 

my guess would be catback as its the longest dunno haha

 

I would think it would be the catback for an SS also. The exhaust mani flows pretty decent for the most part. So thats my guess go catback first!

 

Start with the catback and work you way toward the header. This is so you don't free up an early part of the exhust only to choke it further down the line.

 

could not have said it better myself

 

Didn't think about it that way. Makes alot of sense. Thanks guys

 

i agree start with the cat back, what size are you going to go with 2.25 (GMPP) 2.5 (Corsa, MagnaFlow) or 3.0 (vibrant, hahn)?
