This test is completly legit guys. I'm actully with Al, on this one. Results arent swayed a bit.

Results are right on par with turbomag. They gained i want to say 6-8whp just swiching from hks to greddy ti catback

BR exahust is comparable to a greddy Ti.

Al, I'd put my tanabe up against a BR catback. In weight, and performance.

 

Buschur exhaust is great, however I think that HKS surprisingly kept up well. I was expecting the Buschar to blow the HKS aways since the HKS isn't a full 3" exhaust.

But nice work guys!

Which exhaust are you guys going to try next, Greddy Ti, Fujitusbo, Mine's, AMS, Blitz?

I love what you guys are doing. Keep it up guys.

 

I still want to see Buschur tbe vs Ebay tbe, head to head both from o2 further and both with test pipes.

 

we are going to do some before and after testing shortly with an ebay exhaust... and two other combinations... one catless, one resonated and catted...

ill have before and after dyno plots with afr, boost, and powa!

Everyone knows that HKS is NOT a true 3 inche exhaust and tappers down to 2.5 at the cat and its resonated.. Find another TRUE 3 inch exhaust and test again

 

i heard the rsr, i have is bigger then three inch i would love to test that.with very little bends.

 

cool, so i dont really have to change my 3inch downpipe/test pipe + hks catback system?

 

its already been done, minus the test pipes

 

Was timing made less conservative when you dynoed the Buschur exhaust?

If the tunes were the same for both runs, were you using a tune developed with the HKS or the Buschur system on the car?

Everyone's focusing on the Megan RTP, but I'd focus more on the resonator on the i-pipe that you can't measure.

 

i cant wait for the close.

 

Good test but, I want to see a Megan TBE VS Buscher.

 

who is buscher?

 

o god, here we go.

 

Thank you so much!!! I was debating selling my HKS for a Buschur when I install some other Buschur parts this spring but love the look and sound and fitment of my HKS so I was kinda 50/50 on it. I was expecting far more gains from what people have said but now I think I will keep my HKS. I justified buying it based on the fact that, as you said, HKS is a company that actually engineers its products and DOES do R&D as Buschur and many other name brand companies. They also make many high tech items like electronics and even complete engines for ultra-light aircraft so you know they have a large team of engineers who know there stuff. That and the fitment is excellent which was one thing I always hated about the BR cat back. Although they have come a long way.

I asked for this test back before all the drama on the original ebay comparison started and I got what I wanted. Thanks so much Al and I will see you at BR this summer for another tune.

 

That is exactly what I was going to ask. Seems baseline was done with the HKS, and then put the Buschur on and tuned it for about 8 runs, but oh well. I would actually like to see run 14 or 15.
