Hi,
I'm torn between buying an Axle-Back + HFC (OR) Catback only, Buying an Axle back along with HFC will have the same cost of buying only a catback.

Will there be any difference in power/performance by running axleback+HFC compared to running catback+HFC?

Lets say if I did the uprev tune, any noticable gains will be there for a catback+HFC over a Axle back+HFC?

I went through some topics and people were saying that the HFC is the main restriction in the factory exhaust, So this made me thinking why waste too much money on the catback (other than sound) when I can get a axle back + HFC for the same money and also get the sound and Performace gains?

Let's hear what everyone thinks.

 

Cat back + HFC all day... Biggest bottle neck on Gs are the cats. With a tune you WILL see and feel noticeable gains...

 

Axle back only increases sound no performance gain at all, HFC's and catback will give you a nice WHP gain , With a tune even more.

 

ok thanks
