So my engine will be finished being rebuilt this weekend. I'm looking to do a frankenturbo setup for more daily driving power. I am looking at aftermarket 2.5" next and then the frankenturbo. I was looking at the APR, BillyBoat, or Techtonics system. Does anyone know if there are any REAL differences in these options other than maybe a slight sound difference? I am assuming I should go with a 2.5" vs 2.25" if I'm going with a Frankenturbo setup or bigger. Is that correct?

The other option will be to do a custom 2.5" exhaust, but I'm not sure if the cost outweighs the gains a pre-built system offers me.

Any thoughts or comments are appreciated.

APR = Billyboat

Yeah they look exactly the same on ECS's site. The Billboat is $100 less. So I would definitely go with that setup if I decide on a prefabbed system.

Go with Borla. Just bought one, never regreted it. I was going for APR or Billy Boat, but found a Borla for less, and it is defenitly THE best sounding exhaust!

I always felt the Milltek sounded pretty good. A 2.5" would be plenty but you could always go 2.75".

The Borla listed on AWE tuning is 2.25" and the others I listed are 2.5" I'm thinking a frankenturbo or bigger setup would benefit from the 2.5" more than 2.25". I am definitely going Frankenturbo and nothing bigger for now. So I might be able to get away with the Borla. Any thoughts?

I have APR and I love it! IMHO, its probably the best sound for the B5.

I ran 2.5" on my K03, I wouldn't go any smaller then that for a FT.

Thanks for the vids Biketsai. You just made my decision easy for me. That is the exact sound 'm looking for. I'll probably go for the Billy Boat since everything I'm reading suggests they are identical to the APR. And the BB is less expensive.
