ok, so things went as planned. They were able to get more length for the O2 wire by getting some slack from the wire lome. Fit seem to be perfect, maybe 3/4" to long but the rest of the rubber mounts gave a little. Note: the cats hang down lower and now are the lowest point on the car, may about 2" lower. Definetly woke the sound up some. low end sound mean, but as the r's increase its sounds more tiney, kinda ricey. As for horsepower, No big difference. baseline dyons were 231.2 and 234.2 hp: 221.6 and 226.1 trq. With the y pipe installed (2 hours later, with 30 miles on the car) peaks were 233.3 and 235.2 hp with 223.9 227.6 trq. Have pics of install and speadsheets of all runs......

 

Hmmm, interesting. The Japtrix y-pipe/straight pipe gave ~ 11 HP peak on the dyno. Why would this set up not gain much at all? Even with the Y-pipe alone, the Japtrix one gave ~ 5-6 HP.

 

That's disappointing - it doesn't really make much sense either. Oh well, the exhaust system on our car is extremely difficult to tune from what I hear.

 

wow. I am suprised to say the least! I will consult with acosta racing tomorrow.

VFR350, how is the sound? And can you post the dyno chart. thanks.

 

hey matt, saw your car on Queens BLVD 2 days back. You met us at the Limerock Meet in CT. We were the ones driving the Envoy on the way up. Just letting you know because while we were staring at it the guys inside the store were giving us dirty looks.

I dont think i was there at the time. But those guys are harmless. I am glad they keep an eye out for it.

 

i tried attaching the dynos, but i seem to have problems with this site, will try again later. It did wake the sound up, low end sounds nice, growls. But the upper rpm's don't sound as good as stock IMO. It did seem to help the midrange right where i drive it, and the graphs/charts show the most gains their, but only a couple of hp.

 

Wow, what a downer a? O well, borla TD exhaust it is i guess...
