Wide bore exhaust

Post  tat2_al on Thu Aug 20, 2009 6:08 pm

Have been thinking about the series exhaust and will probably get laughed at for this next comment but worth a shot.

The exhuast on the series is rather small and pathetic I was wondering on the theory of cutting of the back box and exiting it through the rear PTO hole and fitting a cherry bomb or similiar on the back (in effect a striaght through system). I realise this won't make the series faster or anything like that but I am assuming (and probably wrongly) that it should have the desired effect of making the throttle a bit more responsive.

Any sensible criticms welcome? any un-sensible ones will still be read just made to stand in the corner afterwards. Laughing Laughing

Just to help some visualise the series exhaust system here is a diagram of complete system.

You want more power not less as you won't have any back pressure lol!

I thought a straight through system would be better as bits and bobs I was reading on exhaust less bends and striaghter pipes so I thought no back box and heading straight out the back would be the way to go.

Obviously not.

What would you recommend?

if you do fit a cherry bomb or similar, you will still have a full length system most of which is standard bore, so "backpressure" will still be enough to protect your valves but airflow will be improved, throw the oilbath air filter in the skip (if you haven't already) and replace it with a K&N cone filter or similar, and the overall breathing will be much better.

I've done this (minus the backbox) with my 2.5 petrol 90, but with an SU carb as well. There is a noticable difference in power!

Best thing to do is chuck away the little 4 pot petrol and refit with a 200/300 tdi or be strong and fit a v8 on lpg that will make it move affraid affraid

V8? maybe one day.

No thought this would be a cheap and straight forward mod that as said would improve throttle response a bit with the added bonus of sounding rather nice.

Oil bath was first to go! got the K&N filter that paddocks do not a cone just a standard cyclinder, it is planned on getting moved as well as at the moment it sits directly on top of the carb directly under the bonnet. Problem with that is as the engine heats up so does the air less effecient so planning moving it to top of a snorkel or at least outwith the engine bay so it is getting cold air. suppose its similiar to an iduction kit of sorts ish.

just thinking about the the theory of making it move. would I not have to change the gearbox as well for a V8, with it being so low geared would a V8 not rip it to bits?

You know that you are supposed to be looking at the exhaust and not what round about!!

There is no boxers there they are tea towels, Irn bru collection build up over long time keeping forgetting to return the bottels to get money back thought sticking them at the front door might help remind me . . . . it hasn't.

On the back of the door is Morag
