Well, got some time to take pictures today and so i thought i'd post up photos of the embarassing "exhaust fall off car" situation. I had bodged an exhaust together a while back and got complacent with it. On reflection chosing old used exhaust pipe to construct the exhaust was a bad idea. This is what it looks like now, which is asking for trouble as its relying upon only 2 rubber mounts now (one of which is rather perished :eek:) and its also going to be loading the join from the silencer to the mid section as its just not supported anymore. :(

The bill i am sure is going to be huge if I ask for the header to be designed aswell, but will see tomorrow. Should sound lovely after Its done though, and the cost of the exhaust (maintainance wise) will be low as i'll be using a mini RC40 exhaust silencer (about £30 a go i think). I'll have to be mentioning a certain abarth possibility i guess aswell. Just in case they need to change the design atall.

Gulp, time to bite the bullet on this one. Although I'm sure its a good price, £250 is alot to pay. Wont have to buy another exhaust ever again though :D yeeehaa!

Funny thing is, the exhaust is lifetime garanteed. I exect for the reason that peeps dont keep their cars for long and generally dont expect their cars to last as long. I think I'll be keeping mine for long enough that they'll need to replace the silencer :cool: But under warranty, hehe.

Generally excited, cant wait to hear it purrrrrrrr. I am terrified the exhaust is going to fall off as it is. :eek:

I'll post up sexy pics on wenesday :D yay!!

£250 ain't bad cause you'd pay that for one of them funky Mk2B panda exhausts (you know with the flexi section in the middle and the cat).

I'm going to have to invest in stainless steel shortly as I go thou them like no ones buisness. Where did you get yours Si?

If the workmanship's good then £250 is a good price, especially considering the guarantee. If my Panda's future wasn't a grey area then I'd get one, but a standard system is good for the moment and still sounds good, especially after a long run.

I wouldn't recomend a stainless steel system for your car Jim until you find the cause of the failings. Stainless steel tends to be more brittle than mild steel and if stressed cracks more easily:(

btw the springs arrived last week(y) many thanks Damon
 
Right, just got back from the "day of the exhaust" :slayer: Been out and about for a while now. am knackered walking back to get my car. Bus wouldve been a good choice. :eek:

Anyway, the exhaust is fitted and sounds great. Only problems are its possible a bit too loud. I asked for "medium to sport" which is perhaps a little too loud imo. It isnt excessive though, so not gonna be crying over it. They bunged in a free exhaust end upgrade for me which was cool. Looks sweet, but they were out of the size i wanted and so its a little bigger than i intended :rolleyes:

Over all they give a good serive, so recommend it to peeps. Be specific with what you want is my advice though. They literally build it to the spec you want down to the angle you want the exhaust end to point out, loudness, the end style, etc.

Pictures to follow! too dark for pics atm.

Cheers, Si
 
yeah, that was my bad :eek: I did that when i fitted the exhaust before it. Its only a slight indent though, so nothing majorly destructive. Just thought it looked better as high up into the bumber as possible without actually vibrating up against it.

Love the sound she makes when starting now :cool: and a lovely burble on idle too.
 
Hmmm, think I've confused a rather simple situation here. Anyone from this corner shed some light on the issue of power loss with the new exhaust?

I think its performance is improving now though, from the drive earlier today, but will have to see how it goes tomorrow i think.

New exhausts need a carbon build up in the baffles to take the tinyness away if you know what I mean It may be very loud new but when the carbon builds up in the baffles it will get quieter...

Secondly unless the bloke that designed the exhaust knows what they are doing you will loose power. Less restrictive is only one point in additional performance, if you were to remove the exhaust completely it would be much less restrictive BUT as everyone who has lost a back box will know the opposite is in fact true.

The exhaust is quite a complex design and is designed in shape, thickness for the soundwave to enhance gas flow. If designed incorrectly the soundwaves can bounce about to such an extent that it will reduce gas flow even if much thicker than the original exhaust.....

That all sounds right. I think i'll keep looking for my technical advice in the panda section from now on!!
I have been reading into it the last few days. As far as exhaust design is concerned it is as you say very complicated and all about tuning it so that pulses of gas work to aid scavenging of the cylinder by altering the length and diameter of the pipe. Alot seems based on experience of exhaust building aswell. So much to read into, but I have found it very interesting. I would love to have a go at building my own LCB manifold if i can. But that entails alot more information than i currently know. Although, some coursework I did last term (on my engineering degree) would apply to this. We covered sound in a pipe and air flow. Anyway, interesting stuff. :cool:

Only bit i couldnt find out, from internetting madly, was the effect of carbon build up inside the exhaust. Do you know, does it effect the flow and so the performance atall? I am thinking as carbon builds up on the inside of the pipe, the pulses of exhaust will travel at different speeds allong the pipe maybe? As I have been reading, the length of the pipe must be such that when the exhaust pulse reaches the end and exits to atmosphere, a low pressure refraction wave travels back down the pipe and must reach the exhaust valve a little bit before it closes to scavenge any remaining gases out of the cylinder ready for fresh new Air/Fuel mixture to be drawn back in.

Sorry I am getting carried away with my thoughts! Thankyou for your comments though. Just got told my engine is "fecked" (nice and technical) over in the other section :eek: :doh:
Cheers!!
