NeilTindle Posted November 7, 2006 Report Posted November 7, 2006 My 1994 2.0 GLX is going to need a rear silencer soon and I was wondering if it was possible to get a a less restrictive replacement. I've had a search on here and on the net and can't find anything. Anyone know where I can get one?Cheers, Neil Quote

Anyone know where I can get one?Cheers, Neil Hi Neil what you need is a Dunstall Thunderclap 4 into one ...... makes an awful racket and looks really cool ..... espiecally on a MOTOR BIKE!!!!! Since when was a Galaxy a Sports car in need of an unrestrictive exhaust? I thought the idea of an exhaust was to feed the exhaust gases away from the car? Quote
Guest HairyPlateEater Posted November 8, 2006 Report Posted November 8, 2006 Ignore old man Bleeno .... he's turning into Victor Meldrew more and more lol I'd be interested in hearing if you find anywhere that does performance backboxes for the Gal too. I've looked and can't find much about. Fitted a stainless number to a Suzuki Vitara I had and the fuel economy benefit was worth it alone. Quote
tim-spam Posted November 8, 2006 Report Posted November 8, 2006 Unless the exhaust is a principal element in limiting the performance (which it won't be), you are very unlikely to gain any significant performance or economy benefit from a 'performance' exhaust, unless other engine changes are also made (head work, remap, cam, induction, etc.). If, however, you are just after a different sound, it may be just what you want. Thinking about it, though, if the 'performance' exhaust was noisy enough to encourage you to change up earlier, you may improve economy slightly. But then again, if it sounded really good, you may spend more time revving it to the red line - then economy would go out of the window. Quote
seatkid Posted November 8, 2006 Report Posted November 8, 2006 Try fixing one of those old corrugated steel dustbins. Should make it go like stink. :( Quote

Guest gooner52 Posted November 8, 2006 Report Posted November 8, 2006 did you pit on a full system h or just backbox :( Quote
Guest HairyPlateEater Posted November 8, 2006 Report Posted November 8, 2006 Stainless mid pipe and backbox with 3" roll edge polished tail pipe. Original manifold and front section though. Noise was nice - gave a deep pop and burble on downshifting too. Was the fuel economy improvement I was after though as was doing around 2500 miles a month then. Independant 4x4 dealer I got the car from originally recommended the pipe as he had the same thing fitted to his Vitara and had the same improvements. The Dakar 10" wheel and arch kit came next ..... then the removable hard roof :( Quote
tim-spam Posted November 10, 2006 Report Posted November 10, 2006 There must have been a pretty serious flaw with your original system (baffles adrift/misaligned, partially blocked, basic design wrong, etc). On a properly designed modern car, it is very difficult to obtain any significant improvement in either performance or economy by changing the exhaust alone. A Galaxy exhaust system will have been properly designed and matched to the rest of the engine systems. But, if you really want to go ahead, then go ahead - it's your money. Quote
Guest rambo Posted November 10, 2006 Report Posted November 10, 2006 back on the performance exhaust topic i got one for my old mondeo, before the gal came along from a company called sportex they are on the net and it was a straight bolt on re-placement, fitted a treat, started her up and thought oh on it dont sound much different from the standard one a little bit more throaty but not enough for me, so i rang them up and said it sounds shit, the guy said you have to take your middlebox off as it is designed as a straight through system, so i chopped the middlebox off fitted a straight bit of exhaust pipe in its place which i aqquired from the local kwik fit dustbin and wow what a sound, but that was then and this is now if you want a replacement performance box try sportex if not just buy a universal one from e-bay with the same diameter as your gal and saw the old one off bobs your uncle and all that jazz! it wont sound that loud but will look nice if you want it loud take off the middlebox, i was crapping myself at the mondeos first M.O.T. with no middlebox but it went through no probs they guy said as long as the cat is not removed emmisions is not a problem it wont affect it, rant rant rant hope this is of some help :blink: Quote
Guest HairyPlateEater Posted November 10, 2006 Report Posted November 10, 2006 There must have been a pretty serious flaw with your original system (baffles adrift/misaligned, partially blocked, basic design wrong, etc). On both Vitaras it was fitted to? Not usual for modern Jap cars to be designed with flaws, that's usually Vauxhall's monopoly! On a properly designed modern car, it is very difficult to obtain any significant improvement in either performance or economy by changing the exhaust alone. A Galaxy exhaust system will have been properly designed and matched to the rest of the engine systems. But, if you really want to go ahead, then go ahead - it's your money. In this day and age it will have been designed around emmission control above everything else. 3rd party performance exhaust manufacturers design the exhausts to develop better performance and fuel economy while still keeping the car within emmission limits for each individual model they design them for. Different priorities produce different results. I'm not saying that every non standard exhaust will give better fuel economy, but in my experience an exhaust that's designed/proven to give better economy, it will give better economy! I re-couped the cost of the exhaust in around 8 months in saved fuel costs so my money was well spent. Taken from Edworthy's website .....

A side benefit is the deeper, throatier tone produced by the exhaust system. Because your car Quote

He aint far wrong there! if you look through the projektzwo back box I have on the shelf it's just a big length of pipe linked too the twin outlets with some sound deadening material packed around it :blink: Quote
tim-spam Posted November 12, 2006 Report Posted November 12, 2006 If you really want to believe that a 'performance' exhaust on its own can give you any significant improvement to either performance or economy (were you claiming around 15%?), then go ahead - it's your money......... Quote
Guest HairyPlateEater Posted November 12, 2006 Report Posted November 12, 2006 I do believe it, as it happened. It was Edworthys claiming the 5-15% improvement. Shall we just agree to disagree ..... :rolleyes: Quote

tim-spam Posted November 13, 2006 Report Posted November 13, 2006 It's really quite simple. The car industry spends huge sums of money trying (and succeeding) to improve the performance, economy and comfort of its products. Exhaust systems have an effect on all three of these, and a great deal of effort is put into meeting the backpressure requirements of the engine (this is vital in ensuring that the power, economy, emissions and noise requirements are met), the quality (not just the quantity) of the noise made, serviceability and durability (both in terms of corrosion resistance and fatigue life) and, of course, cost. Now, if the cost constraint is removed, and with access to all of the analytical and test equipment available to the average car company, it may just be possible to achieve a measurable improvement in efficiency, but it would be very small indeed. However, if you are after a different sound and a smarter look, a special exhaust could be just the ticket. It may be difficult to find one made for the Galaxy - you could try some of the German companies who produce tuning parts for VW group cars. Good luck. Quote

I'll have you fitting 6" big bores to every car you see before you know it ........ :) :ph34r: :wacko: :rolleyes: :lol: Quote
tim-spam Posted November 13, 2006 Report Posted November 13, 2006 Maybe......but by measurable I meant measurable on a dynomometer - perhaps around 1%, maybe 2% if the original wasn't much good. I've actually measured 'free-flow' exhausts that had a higher back-pressure than the standard exhaust, as well as being noisier. The main reason in this case was the smaller company's need to restrict themselves to standard material sizes for the internal components, and space limitations dictated that this was the next size down - oh dear. The smaller size increased restriction and also the exit velocity of the exhaust gases - hence the noise. Car manufacturers can, and do, spend millions on tooling, and, if the optimum pipe size, for example, is an i.d. of 68.5mm, then that is precisely what they will use. Quote
seatkid Posted November 13, 2006 Report Posted November 13, 2006 Broom, Broom! May I first state that LOUD exhausts are a pet hate of mine! :rolleyes: Secondly can I also state that........oh why do I bother?....no-ones listening anyway..... :) Quote

Ghia-X Posted November 26, 2006 Report Posted November 26, 2006 Both Remus and Sebring make a rear twin box for the Galaxy but they arent cheap . I went for a Sebring twin box on my first 99 2.3 Zetec . It was nicely made , extremely heavy , cost me Quote
