Buschur Exhuast testing - + 23 WHP (dyno sheet and Video!)
From Al's first post, it seems like the car had the stock downpipe and cat in place.
quote:
"In this case the customer had the Br Intake, upper and lower fmic pipe, mini battery kit and some Greddy exhuast"
"in fact it was a Greddy unit with a giant S bend at the muffler - a extra resonator and a neck down at the cat."
Guess what happens when you replace the stock cat with a test pipe on a 3" Bushur exhaust: Going from the 2.5 dp with the stock cat and a 3" catback to the 2.5"dp, offroad pipe and 3" catback increased the power by 20 whp and 22 ft lbs of torque.

After I took a break, I was walking back up to the dyno and happened to notice the exhuast tip did not look like a Buschur exhuast - in fact it was a Greddy unit with a giant S bend at the muffler - a extra resonator and a neck down at the cat.
now, test the Ebay or Megan full 3" exhaust vs. BR full 3" exhaust and i'll give you all the credit in the world.

And you say that you put the buschur exhaust on and " no tuning , same boost , same air/fuel" Wouldn't the air fuel lean out if the new exhaust did infact flow that much better??
Don't get me wrong im not saying that buschur's parts don't work well. Because they do. Its just we get it already, Can Dave get you to stand out infront of his shop in a giant spark plug suit too??

We did a true A - B comparision
Unlike - for example in previous tests where I mad ethe fueling adjustments - (yes i have tried it both ways and the Buschur unit has made more power eaxh way).

Thank god
With the video of that cat back it is clear that the design of thier cat back section leaves a lot to be desired from a performance point of view
it amazes me that people will waste any money on any cat back with a neck down at the cat area - its simply an un-needed restriction made to satisfy some foreign emissions rules
the giant S bend and the extra resonatior are other features which simply ROB power
I am glad to see a vendor who sells these kind of systems on here supporting this type of pwoer robbing design as it shows a clear example of how it is that customers are mis - directed into buying these kind of systems when there are many other options which sell for similar price points but which make more power

just to clarify, this test is NOT a full 3" vs. full 3". that neck down is what probably rob the most power. so you can't say that not all 3" pipe are the same because you didn't test a FULL 3" pipe. you also tested an exhaust with a cat vs. an exhaust with a test pipe.
now, test the Ebay or Megan full 3" exhaust vs. BR full 3" exhaust and i'll give you all the credit in the world.

Just to clarify
Any one who buy's a "full 3" " exhuast that has a neck down is getting hosed
neck down serves no function other than to satisfy obscure emissions laws in other countries
The real well made performance exhuasts all are 3' all the way through and have no additional resonators or giant s bends to rob power .
As a memeber said before I would like to see a true same parts test. Take any full 3 inch with high flow cat and down pipe tune it the swapit with the Buscher. Personally when I got my exhauts I did a lot of home work and this tread was still here(2 years ago) Buscher makes more power than any other....But I did not like the sound or look. So I got the Tanabe Hyper TI FULL 3 INCH ,3 INCH DOWN PIPE an high flow cat from MachV. Love the sound and look and gess guys made 373 whp??. Stock turbo, but all supporting mods and tuned by Turb Trix.. NO meth or baby bottle.
i suppose people are entitled to their opnions, but honestly, from a place that works so hard to fully ensure that their product isnt a total waste and will get you everything you want TOTALLY AMAZES me. They seem so dedicated to making a perfect product which in my opinion is awsome! the strive for perfection....
^^^and may i mention that i made 331whp and 337torque with just a Wartalon/BUSCHUR package that i spent only $1270 on NO IC piping either.....AND a MAIL IN TUNE BY DYNOFLASH AL... and i see some evo owners putting on these flashy $800 exhaust systems that dont make the power they should...




My fault lol.
