well, this is my latest 'secret' mod. as some of you would know, i have a gutted cat converter. as some of you would also know i was dobbed into the EPA for a loud & faulty exhaust (noise & emmissions)
the reason i havent mentioned it earlier is because i dont want loads of questions about it before i've even got it sorted out.
so i've been on the hunt for a new cat converter and i've also been on the hunt for a quieter muffler. i have found the quieter muffler thanks to urq with his stock trx muffler, i was offered one from sssgtr, but i have read somewhere that the trx mufflers have higher flow rates.
the cat converter i have chosen is a stock magna cat converter from a TJ 3.5 litre sports model.
the inlet and outlet of this cat is 2.5" a perfect match up for my 2.5" exhaust.
the overall dimensions of the magna cat converter are 430 x 190 x 100mm
the length was taken from outside of flange -> outside of flange. the height & width is the overall size of the casing. the actaul width of the honeycomb section of the cat is slightly smaller (165mm).
this cat is approximately 2.5 to 3 times larger in volume than the stock trx cat converter, so its good for plenty of flow.
the magna cat converter, 2nd hand, cost me $110. you can probably find something cheaper if you look around more, but because i am running to a deadline of march 24th to get to the EPA, this one was the first one i found in 2 weeks of searching so i grabbed it.
for installation, i have been quoted $90 from carline in northcote and $100 from ace exhausts in ringwood.
the reason it costs so much is that you have to have magna flanges fitted to your pintara exhaust, you have to have a section cut out of your pintara exhaust and you also have to have new mounting brackets fabricated.
i'm booked in to have it all replaced on wednesday which has cut my deadline very very close. so until then i have no photos of it installed, however, i have a photo of the stock exhaust system showing the stock cat converter (taken from autospeed) and also pics of the new cat.
i'll provide updates as i get it, but please dont ask any questions about how it goes until then unless you want me to get pissed off with you.
first pic is a pic of the stock exhaust showing the stock cat.
second pic is a pic of the magna cat next to a 750ml bottle of cordial so you have something to physically compare the size
