Mini Spares bolt-on performance kit for 998 and 1098 engines (will require 1-1/2" carby). Gives 20% more power and 12% more torque. Kit includes - single box RC40 exhaust system (double shown), Maniflow Cooper Freeflow exhaust manifold, Torquemaster inlet manifold, K&N air filter element, carburettor needle, exhaust fitting kit, and gaskets for the carburettor and manifold. $595

I have the perry, 1 3/4 and rc40...
can be considered loud, but I don't have any door or side trim yet.

IMO you can't go wrong with either..

Thanks for the input guys!

Unfortunately a custom kit is out of the question as I am pushed for funds.

I realise that everyone has differing opinions but overall is this my best option? (see below)

Carby: 1.5" SU

Inlet Manifold: Minispares/Minisport Water Cooled

Extractors: Maniflow Medium Bore LCB or Graham Russel's Supa pipes

Exhaust: RC40 Twin Box

Which is really the Minisport Kit but with a Twin Box?

Hello everyone I have to get a new exhaust for my new engine and am unsure what i should run. Engine is a rebuilt 1100 with a worked 12g295 head to go into a clubby van with a 1.5 su So my question is what should i run in the way of extractors, exhaust and what is best suited to a van (as it is 4" longer)? I can easily get the extra length welded in. Thanks in advance and sorry if that was very vague Matt

the doc has recommended i look into getting a perry LCB, 1-3/4" pipe and an RC40 and weld 4" into the front pipe. Or get an aftermarket manifold and run a set of maniflow LCBs. Or should I get: Minisport Website wrote: Mini Spares bolt-on performance kit for 998 and 1098 engines (will require 1-1/2" carby). Gives 20% more power and 12% more torque.

Cheers Matt

Blah! bugger the imported stuff, the local stuff can be had for a bargain and works a treat. I am a fan of the Maniflows with the cast ends though...

Mini Mad wrote: IMO you can't go wrong with either.. Josh what are you running on Spiro? Seeing as it has a similar wheel base to the van? I am going to look at some local stuff aswell but these seemed to be the best options to me At the moment i am leaning towards the Minisport/Minispares Kit as I get everything I need. $595 seems pretty good to me can anyone think of a better kit or a better price! Any other suggestions? Thanks again Matt

Call Graham Russell for his Supa Pipes, around $450 and they are proven to work better than most other offerings (as per The Mini Experience). They achieved the best hp figures on a 1098cc and produced a total of 95hp. I've dynoed my 1330 with these vs maniflow medium LCBs and I'm sold on them even though he tells me not to bother and stick with my Maniflows About the only thing better is a custom, tuned length and diameter, mandrel bend pipes like on Group N race cars, but then you are looking at $$$$ No he's not paying me. He only has a few sets left... Here is the article for you cheapskates who don't want to buy TME magazine http://www.minimania.com/web/SCatagory/ ... ticleV.cfm

The article says it all, it contains many of the types you are talking about. Beware there are alot of chinese copy maniflows out there. The easiest way to tell the difference between genuine and copies is the Y piece. The copies will have a Y piece that is vertical not horizontal in many cases, and the join between the 2 outer pipes come together in a join that is on top of eachother rather than a complete "Y" configuration. Before buying, compare pics to the real thing from maniflow's website. There are a few second hand sets out there too and... i might be selling mine if you need a set (the ones that look red hot in the picture on my rebuild thread )

any LCB extractors, into a 1inch and 7/8ths exhaust pipe, put whatever muffler you want on it, if you have extra money, put a flexi joint and or flanges.

Extractors - Maniflow Medium Bore LCB, or the GR Supa pipes Exhaust - RC40 Twin box (don't use single box, noisier and make less power, and transmit more vibration to the shell!!) Inlet manifold....Hmm, go for a mini spares, or a GR (watch clearance here), or there is a nice maniflow item too. Take it all to an exhaust place you can trust to get it fitted properly, they can extend / fabricate the extra length you will need.

Matt The minisport kit has a freeflow exhaust manifold, not an LCB, but yes, it is the same apart from those two differences!! The inlet manifold is actually a water heated one, not needed in Oz in MHO. Much simpler to locate a good second hand i.5" inlet or get a GR one. Or you could go twins!!

Oh, And stick to a 1 3/4 internal diameter system, anything larger is WAY too large. The RC40, maniflow extracvtors are this size. Cheers matt

What is called a 1-3/4 system here is 1-3/4 diameter OUTSIDE the pipe. Tube (which exhaust `pipe' is) is sized on OD, unlike water pipe etc. Exhaust `pipe' is 1/16" (1.6mm) wall thickness, so the sizes nest nicely inside each other in 1/8" steps. Metric sizes??? go wash yer mouth out..
