Power Gains With High Flow Cat And Dump Pipe?

[rhodieee]

Hey guys! I'm running a full exhaust system on my 33 s2. Only thing that's stock is the cat and down pipe. I bought a 100cell high flow cat today and going to buy xforce down pipe within the next couple of days. Was wondering if anyone has experienced power gains with changing these items. Anyone feel a difference in power at all?

Yeah just make sure you get one for a 6 cylinder if yr putting it on a skyline cos my mate put one on and now it only runs on 4 cylinders so we think he got sent a 4 cylinder one by mistake.

You will have a slight increase.

ok yes the downpipe is worth it but make sure downpipe is bellmouth type, and if you can port-match it even better. My own testing back to back, split did not make as much power as bellmouth.

This had always interested me and no one has posted results before. Even on other platforms.

What were your findings?

Think of larger exhaust as a support mod, it will not give you increased power right away, but is required when you want to push more boost and will help you make more power when you do that.

You might feel it a little bit but that's subjective really.

Hey guys! Well I got it done today... Honest opinion it spools up much more quicker! I can feel abit more torque at the low range rpm and it holds boost really well aswell!
