Hey guys, just came back from a session at the dyno to test the Buddy club dual Pro Spec exhaust.
Call me a ricer, but I wanted something with a dual tip for that symetry. I know it's more weight but I'm still saving 10kg's over the stock exhaust (which is so damn heavy) so it's all good.
Here's a before and after dyno test performed in shootout mode on IS Motor Racing's dyno last night.
I suspect exhausts have to bed in and potentially more gain would be had if we dyno tested again in a few weeks. Although some people are very particular about dyno reading accuracy, and would prefer to see dyno test performed at the same time on the same day.
DYNO BEFORE
AFTER
COMBINED
A healthy gain. A/F is a bit crazy now with the exhaust, some tuning would be good down the line.
Some of my pics:
Beautiful design and build quality (something that's been questionable about some other BC exhaust products but not seen in this particular design/model).
OEM exhaust was ridiculously heavy.
With silencers in (also, new plates!
)
REVIEW:
Make: Very nice welds, love the symetrical design more than anything else. Really nice piece that splits the mufflers. Fitting was easy and perfect, ISMR guys said it was a pleasure to install, plenty of room to get hands in and around, perfect fit. Strange then that Rix/VTECMACHINE had so much trouble with the DC2R design, perhaps they've picked up their game? We'll soon find out when we install and test other exhausts from the range.
Sound: Sound is just nuts at WOT in VTEC. Hitting the START button is a different experience too as the exhaust growls when the engine's started. The note is far from raspy, instead a very deep bassy tone. Really nice on idle. I've driven it around for a couple of days now and I have to say it generates a lot of in cabin drone. It's not that loud from the outside, but inside the car it drones a lot. You can reduce the droning, depending on how you drive it, and what gear you're in, but it's definitely not for everyone. I've fitted the silencers that came with the exhaust today and instantly noticed a lot less noise but there's still a fair bit of drone. I'd be curious to see if cutting out the main resonator and putting in a bigger hotdog would help to reduce drone, might be something I will look into in future. I'm also curious about doing a dyno run with the silencers on.
Performance: All the noise the intake and exhaust is adding makes the car feel 10 times faster, of-course, it's not 10 times faster though. Taking off at the lights and 1st into 2nd gear at slow speeds is a lot smoother, less hesitation.
All in all I am happy. The drone's pretty bad but the gain is good. I said out loud in front of Indy and Chris last night, that if the exhaust was to lose power, I'd quit Buddy club as I'm far too honest a guy to try and sell a product which fails to work well! So I'm happy about the gain and looking forward to testing more gear on more cars.
We'll be sending out PM's soon to invite a DC5 and a DC2 to test some products. Of-course we'll be dyno testing everything and posting results. Any more questions about this test, feel free to ask!
