I am not in a position to go spending 600+ on a new exhaust, but wonder if anyone has tried a bigger dump without Cat and-or removal of main muffler box? I can't find one listed for sale that would bolt straight into standard system. Anyone know of one?? cheers.

gday skamme, i have none some people who have precisely cut open their cat converters and removed all of the gunk/baffling inside then tig weld it back together.....

not sure why you would want a bigger dump then back to standard exhaust system??

my opinion, just spend the money mate. even if it takes that little bit longer to get

cheers

I Removed my cat and replaced it with a 2.5 inch hi flow (mandrel bent). By left the rest of the system standard just to see what would happen cause the dumps or only $110 buks and it made it easy to mount the EGT probe. I have no doubt the complete system will be better which i'll get around to eventually, but i was surprised the difference it made. Definatly abit more perky off the line. If you on a budget id say its not a bad mod.
Got mine from a place here in Perth and the rest of the 2.5 mandrel system is only 400 and bolts up to the dump so i'll just do that.

If you are in Brisbane, give Fat Pipes a call. He will do you a without a cat for around $500. 2 1/2 mandrel dump pipe with a 3' press the rest.

Just gutting the Cat will noticeably improve performance. Removing it all together is better. Gutted it on my TD5 Disco and fitted a vortex muffler to replace factory one. Very noticable perfomance increase and better economy. Would be the same on any Diesel.

I have a 2.5" dump straight through no cat, has not made much diff if any, I think the other option is to replace that 1st big muffler as well with a 8" straight through muffler, thats my next thing to do.
