on the 2nd to last chart... you got the names wrong at the end of the file name.

 

so the borla exhaust alone made more power than the tanabe, hks and joe z combo. not bad.

 

I must say I'm really disappointed in your video directing / producing... There wasn't any video of the most important scenario ... the car at WOT driving away from the camera...

I'm really surprised by the AFRs for the dyno runs. It seems odd to me that the richer fuel curve is making more power.

 

Thanks for noticing that. I was in a hurry and got them mixed up. Fixed now.

 

Yeah I would have loved to get more video, but he had to get to work and we spent more time at the dyno than expected. It really does sound good at WOT and is definitely not loud as you would expect with the rear cats being deleted. I think my tanabe is louder than his Borla in normal driving, but under WOT his exhaust has more of a note and mine seems to get quieter.

Gernby, you, I and the rest of the shop were surprised with the a/f and power results. Typically you would expect more power with a leaner curve. I wonder if he were to tune it leaner his power would go up with the increased air flow.

 

we'll have to get a better vid than that..that was my fault cuz i didnt use enough throttle

 

so the fujita intakes are losing 15hp?

 

15hp not bad!

BTW, only difference between the off-road and street Borla exhaust is the cats so you could save yourself the extra $ that Borla charges for the off-road and have your installer put in 2 straight pipes in place of the cats.

Wayne, I'm curious as to how much drone you get - I still get some at 2000-2500 RPM but its reduced.

 

Emil, let me know when you are free for a few minutes and i'll get some better videos.

 

Why cut up the stock exhaust just to save $100? The $100 difference between the 2 versions would be well worth it considering the off-road version doesn't require any cutting at all.

 

Wow, 6HP for the Joe-Z intake? thats awesome! I will consider one for myself

 

only drone i egt is in sixth gear @ 3500 rpm..but just a littlle throttle or a little less and its gone

 

yea..heres the difference:

Now that I see both versions of Borla exhausts side by side, I think they REALLY screwed up on the street version! The "off road" version has what appears to be a better X-pipe and it also has dual resonators before the mufflers. The "street" version has a crappy looking X-pipe and no resonators. Now I'm really curious about the sound difference. I wouldn't be surprised if the street version was louder than the off-road version.

Street version


Off Road version

 

i have the LMS catback. and thinking of getting the Borla.(off road of course what do you guys think? would there be much of a difference performance wise?
