New exhaust on today

richo77 · 17-10-2005, 07:07 PM

Hey all,

Just thought i'd share that i picked up my XR8 this afternoon after having a twin 2.5 mild steel cats back system put on at Genie Exhausts..

I wish I had done it ages ago!! As soon as I started the car it was the sound i've been wanting for so long. At idle it sounds great and when I gave it a bit of a gun on the freeway it sounded even better.

anyway they dynoed the car before and after its gone up a little from 242.13 hp to 256.82 hp with its best increase in the 3,500 - 4,500 range. i wasnt really worried about any power gains so this is just a bonus.

another good thing was it finally solved an ongoing rattle when going over potholes, speedbumps etc This problem which could not be solved by Ford despite 'resetting exhaust system position' and the service advisor complaining that his techs spent hours trying to track the problem turned out to be a bent bracket.

:
cheers
Nathan

ok i'm going to machine buff and wax it this week and take a few pics of it, basically its just the rolled stainless twin tips which are angle cut if u know what i mean.

Hey Richo, I got the same thing as you and wondering how much a cats back system costs for an auIII XR8. Also, how much better does it sound?

richo77 · 21-10-2005, 01:47 PM

yep it sounds so much better, its best at start up and idle and when your giving it some squirt. its also pretty quiet at freeway speeds which is what i wanted.

was $750 all up with the stainless tips.

There good figures for a AU3 after doing the exhaust going from 181rwkw or 242rwhp to about 191rwkw or 257rwhp
I take it the rest of it is not stock and a manual
Good stuff

richo77 · 24-10-2005, 08:59 PM

Thanks for the compliment mate, nah its only an auto unfortunately and the only other mod is a K&N panel filter. Is that a decent figure?? what other figures are around?

Lightning Strike GT · 25-10-2005, 09:18 AM

Mine is the 200kw version in manual and the last dyno I did it was a tad under 170rwkw or 227rwhp and that is with exhaust and a K&N and an extra pipe in the front of the air box to collect the cold air from behind the headlights as well so 190rwkw out of an 220kw auto is very good with the mods you have done
BTW who is your engine builder - his name should be on the RHS rocker cover

heya mate the engine builder was "S Berry".
Some of those other names on Aufalcon.com sound like engine building was outsourced to a foreign country like a lot of the call centres these days!
cool i must be a lucky one to have a good power output in standard form.

Richo77,
Yeah i wish that i stayed with the twin instead of 3" single even though it sounds awsome it sits to close to the ground.

Yep you are right sounds like a roll call from Bankstown High but they seem to be great engine builders as I think FPV have the same guys building the Boss motors

Yep I was going for the single 3" but the exhaust place said the same thing as speed bumps, rough roads and angled driveways would tear it off or put dents in it , the twin 2 1/2 is definately better for clearance

Oh well ill just see how i go if it gets damaged ill replace it.
