Al i would like to see how a TXS exhaust compares to the buschur. Ive always made good numbers with both my evos running the TXS. When i get the car fixed maybe ill take a trip down and we can do a test on a competely built evo...
Im sure the buschur is lighter but I would like to see if it makes a bigger difference in HP on a fully built evo..

Well....
I am pleased to hear that Al and to see that this was a good comparison between two TBEs.
I do not doubt that BR would make more power than the HKS. BTW, I have a BR TBE and my buddy has the HKS with same mods. I always run in front of him in 2nd and 3rd pulls. Maybe is the driver! ;-)
Very impressed how close the HKS was to the BR! Good informative thread!

When the Buschur unit was first put in it was a bit leaner on the top end
I dialed in the a/f tables 100% the same and the same timing to try and make as close a comparision as possible
You can see the a/f curves and they are nearly 100% identical
I think the reason why I did this was becuase the power was so close between the two the gain / or loss could have been explained by tuning alone - which is why I wanted the tuning to be identical
The near 9 whp gain in power in the Buschur unit up top required a increase in fuel
I hope that explains why we did a lot of pulls on this car

It should be noted that the taper at the cat is soooo slight. I think most people who ***** about this dont even own this exhaust or have ever looked at one in person. Also, look now straight the HKS is. Very similar to the Buschur and actually eliminates one bend compared to the Buschur. I think that is why it makes good power. Some other brands have bends that do make a difference. The HKS does not.
