do you think it would be worth it to change from a COBB TBE to a BPM TBE??
The BPM is a true 3" exhaust from the DP back meaning it does not taper at all...the COBB does taper a bit from 3" to 2.75" in places...I say BPM all the way...I have used both and the BPM does sound better to me...but as far as performance I don't think there will be a huge difference.
Its all up to sound preference. The taper isnt a very big deal. If you are running an outrageous turbo set up and trying to crank out every little bit of horse power then I guess the .5in taper would bug you. But as far as stage 2 with a protune or even a mild turbo upgrade it really isnt going to effect performance.
I am going with WRX06TR on this one. I just posted in nother thread a write on Cobbs explanation of several different parts of the exhaust and what is what. If you are trying for 450+ or so that little bit wont matter.
