I just got back from dyno-ing my car at ATP. I did a base line run on Dec 10th and I did the last run today with the Borla Hush 3" Cat-back system installed. I cann't post the actually piocs of the dyno results until tommorrow, seeing as how I'm not at work and don't have acces to a scanner right now. But my car in stock form put down 173.4 HP @ ~5.6K and 185.7 ft-lbs @ ~3.7K With the borla hush installed I had 183.1 HP @ ~5.1K and 186.5 ft-lbs @ ~4.3K.

The peak numbers are pretty decieving I think. After about 4.3K the Borla Hush really seprates itself from the stock system. BUt below 4.3K the stock system is putting down better numbers, I already expected that. So I'll put up the dyno grpahs tommorrow so you guys can actually see for yourselves. Oh yeah wanna thank Mike @ATP and Mike @ MPJ for their help.

good results. hurry and get an UP/DP combo

what is the noise difference between the two.

 

At idle they are both same, actually I think I'm idling a little lower. I idle @ 500 when before it used to idle at 750 RPm. When I start the car there is a nice deep growl. At speed I hardly hear it. It is louder than stock but not annoyingly so. At WOT it sounds nice.

And yes I plan on getting a dp/up combo, those sound really nice!! BUt I gotta take care of some home maintenance first Preston.

just as promised. thanks for posting the results. did you have a difficult time switching them out quickly?

those two bolts are a ibt too short and are a pita IMHO

 

Yeah those two bolts were hard. I could quite get my torque wrence to work in that area so I just guest-timated when I was tightening them down. Other than that install went pretty smooth except when the jack I was using to hold the exhaust fell on my hand.

Stock baseline, Run 1 pinged on me; I think because I had a CAI

 

With Borla Hush Installed

 

Dynorun.002 is stock and Dynorun.003 is with the Borla. Now you can compare.

 

Dynorun.002 is stock and Dynorun.003 is with the Borla. Now you can compare, Forgot to add thepic on the psot above

 

sweet.

im glad i bought it now. silent and deadly

 

Me too :banana: I didn't think there would be such a difference above ~4.5K over stock.

 

So is the borla the only mod for the time being?

 

if only borla made it mate up with aftermarket downpipes. Hate to buy something and then start chopping it up. stupid donut gasket

 

Yeah it's the only mod for the time being. I'm trying to pay off my car first, but if one of my plans falls thorugh I'm gonna get my new rims and tires come Feb/March, and then get new springs and struts. Starting with suspension first before I hit up the engine any further.
