Macky's Type-S : for sale £1000 (p17)
Re: Macky's Type-S : new exhaust, part 1
Finally getting around to posting some pics of my new exhaust
The work was carried out by Meercat Exhausts in Kilbirnie, Ayrshire. Famous for making the exhausts for Colin McCrae's private cars, so good enough for me The blokes there were really helpful and friendly
It is a 2.5 inch system. It runs from the downpipe to the back. It has been de-catted and an extra silencer where the decat was keeps the noise down. I requested this as at the time of fitting I was doing 70 miles a day and couldn't face it being overly loud. My new job means I can get the second silencer replaced with a straight pipe if I wish, as I won't be doing anywhere near the mileage
I had to do a 50 mile run-in as the guys said I could blow the baffles if I used too many revs. I also was told to expect the noise to change over the course of a couple of weeks until it settled down.
I was a bit disappointed with the noise at first but sure enough, now that it has been run in, it sounds fantastic. Really deep and growling compared to my old Kakimoto and it has a strange whistle in VTEC, almost like a turbo
Really happy with the results! You may have noticed that this says "part 1"? Well, as predicted, they had a bit of trouble removing my stock manifold, and ran out of time to geet my Tanabe manifold and custom downpipe fitted. The bolts have now been freed up and I just need to get in contact with them once I have the funds to get this completed.

Thanks all
Will check that outBMCC wrote:Keep the box in rather than putting a pipe for the decat in as from what I have been reading you will not make any more power. GMC motorsport is where I read about this. If your interested have a look on their website.
Info from GMC's website:
"Exhaust Systems:
The same problems regarding pipe sizes and lengths apply to exhaust systems, this is why all manufacturers (until Citroen started with VTR) have the Cat or before Cat’s came into being, had an expansion box or silencer just about 3 feet away from the manifold (or a multiple distance of same). So taking off your first silencer and putting in a straight pipe is unlikely to do anything for performance, unless you happen to be lucky that the rear silencer position just so happens to be the correct length away. This is most unlikely as rear silencers are fitted anywhere that room allows. So what about taking off the cat from under the car, the car goes a lot better without it, yes, it does but this is due to getting rid of the restrictions of the Cat, nothing to do with pipe lengths and gas harmonics. So whilst taking off the cat is good it is not as good as taking it off and replacing it with an expansion box in the same place. This is why our BTB exhaust system is so good, not only is it massive bore all the way down to prevent back pressure but it also has an expansion box in place of the Cat. I know this system is expensive in comparison to many others but none has such a big bore, and none have an expansion box, plus you have to buy a De-cat pipe to make fair comparison to price."

Re: Macky's Type-S : new exhaust, part 1
Yeah, I checked that out on their website
Interesting reading. May have a chat with the guy when I go to get the manifold fitted on his thoughts on this. Might be the silencer box with the sound deadening removed may be an alternative? As this would have the same volume but less restrictive?
Nothing more annoying than someone turning up thinking they are some kind of expert after reading an article on the Internet, telling you how to do your job

Re: Macky's Type-S : good/bad/worse news!
Good news
This little lot has arrived:
Bad news is, it didn't arrive in time to get fitted for Modified Live at Knockhill on Sunday. Scuppered my plans to venture out on the track
Worse news, this happened:
Went over a nasty bump and the lip came off at the corner. Must have caught on the road and flipped back on itself. Cracked most of the way along.
Ah well, thats just about every panel destroyed now I have just ordered another JDM rear bumper from Lewis and I suppose I am gonna get some replica Mugen spats to replace it. I was thinking about this along with the Mugen sides as both my Motegi ones are cracked. Just means the car is looking really sorry for itself now! I saw an Impreza today at the shops and it had scuffs and scrapes and cracks all over it, thought it looked like a piece of shiiite, then realised, that's exactly how mine looks
