Borla header
Im thinking about extending the secondary pipes a bit still going to be 2" secondaries and putting a 3" collector on it. Thoughts concerns? ??

Re: Borla header
I've had the Borla for years but do wish it had at least a 2.5" out instead of 2.25". I think Dino modified his to 2.75". 3" might be too big and lose some down-low torque, but I don't know. 2.25" is too small for my stroker is what I know.

Re: Borla header
The borla header comes with a 2 1/4 inch collector and the conecting pipe to the cat is the same size. Consider that the factory pipe gets "crushed" down to 1 7/8" because of the front driveshaft and the borla lookes like a star! But could it be better? If it were a 2 piece setup like the pacesetter with longer secondaries? Only in stainless.

Re: Borla header
Great work. Only wish you would have done a before and after dyno run to verify the real difference.
Should it work better? -'looks' like it should, In theory...
Will it work better? -only the dyno knows for sure.
