Need some advice and parts

Need some help...

Have an EA that has a stuffed muffler, the second (larger one), can I remove completely, replace with a hotdog/alternate muffler, or do I need to put the correct muffler on.

Also, whats the best advice for cleaning injectors. Its duel fuel and runs very well on gas but shit on petrol, I am assuming clogged injectors.

As for parts, I am looking for a cheap boot spoiler and a set of 4 alloy mags.

Any help/advice welcome.

Apparently using a fuel such as Caltex Vortex or Shell Optimax can go some way towards cleaning the injectors. There is also treatment available. Having it done professionally is supposed to be $1-200 from what I gathered?

Firstly it is cheaper to replace the system with a 2 1/2 sports system and sounds great when burnt in.

Secondly, like you I have dual fuel and the same prob, I have had the injectors cleaned (there was nothing wrong there), replaced the fuel pump, fuel filter, and all the electrics, only thing left to do is check the fuel pressure, so I would suggest that you do this first as it is the cheapest from what I am told.

Exhaust stuff

No, you don't have to use another muffler the same as the original. You can fit a hotdog or chamber resonator or straight thru sport muffler or even try having just a section of pipe put in - ie. no rear muffler or anything - you'll still have one muffler and a resonator further forward in the system.

A good muffler shop will let you listen to it before you decide - ie. you could have them remove the muffler and then just clamp on a section of pipe and start the engine for you to determine if it's too loud or sounds yucky - they should be willing to do that with various mufflers, resonators, hotdogs too if you like.

You could even have the pipe size just in that section taken up to 2.5 inch - or even 3 inch if you like - although mufflers, resonators and doggies in the larger sizes will be dearer.

As far as I know you can get a complete "cat back" bolt on Walker 2.5 sport system for about $160 fitted. It uses two "turbo" mufflers and sounds pretty nice - has a pleasant deep burble that's not too loud and doesn't drone. I've got that system on my ED with EFXR6 head and cam and she goes fine - even tho the mufflers aren't straight thru.

If it's the rear muffler behind the rh rear wheel these usually fail where the pipe enters as this is the lowest point and condensation settles here and causes rust; especiall if you do mainly short trips where the exhaust system doesn't get hot enough to evaporate all the condensation in the system. The tip to prevent this is add a drain hole like all mufflers used to have; simply drill a 1/8" or 3mm hole in the lowest point in tye muffler then spray with galvex or similar gavanising spray. You'll be amazed at the large pool of water you find under that hole each morning.
