Cat Info

[Trough Lolly]

ok after many weeks of searching around today my new cat came in the mail.

besides the SMB and "Magic-cat" I think this cat is the much better option to adapt to a STOCK T exhaust or even to a modded exhaust!!

3.5' ends and flows heaps more CFM then all the other alternatives!!

its a "Metal-Cat" imported from the states, I sourced it from nissan silvia forums and the mob that sells them are "option 1 garage" in brisbane.

it was $300 to my door and I must say, this thing is HUGE!!!!

Waht will it cost to get it fitted to te factory dump pipe and centre nuffler ?

<{POST_SNAPBACK}>

I got quoted $100, it would be cheaper but the standard cat diverts into twins that's why its so restrictive. I need a "Y" divider to be installed after the cat so it converts back to the standard twin system after the cat. theres alot of farting around to get it right as its a tricky setup between the factory dump and centre mufflers.

Lumpy, standard dump is 3 1/4' then splits into twin 2 1/4' outputs.

So the actual opening's (pipe diameter?) for the CAT itself is 3.25" in and out, then splitting?

Sorry, just a bit confused by the reference to 'dump'.

3.25 INPUT and twin 2.25 OUTPUTS.

the cat splits into twins in the middle. that's why the stock cat is the most restrictive part of the exhaust, because of the dodgy "Y" shape inside.

Interesting!

I can't wait to see the results. To bad you don't have a custom tune already. If you did it would be a much fairer comparison with the new cat after your retune verus the stock cat.

if people can "feel" the different by removing the centre mufflers I should definately be able to feel a difference as the cat is a bigger restriction.

ill let you all know wednesday how it all goes. hopefully ill get a pic of the cat fitted if I get a chance.

I wanted to get all this stuff out the way before I get my custom tunes next month, that way I have no restrictions holding me back!

The only thing removing the centre muffler will do for you is make you feel the headache from the noise, it flows more then the cat does.

The cat will make all the difference if it really does flow wehat they say. What are they quoting this cat to flow?

well the same cat in a 3' version flows 534.8 CFM so this being a 3.5' version maybe close to 600??? just a stab in the dark guess but its more than enough for 300+atw that's for sure!
