Hey guys
I have a custom RP just sitting about atm..
Item:custom RP
Location: Sutherland Shire
Website:
Item Condition: Looks like a stock 2nd cat.. gasket in good condition
Reason for selling: Dont use it anymore
Price and price conditions: Make me some offers
Extra Info: it started life off as the second cat.. however it has been gutted, and has had a straight through pipe welded in the restrictive cats place. All welds are neat, and in exactly the same place as the mazda factory welds.
So, you'll have a nice race pipe.. that will look stock..
Pictures: if req'd
PM me some offers if interested
Doc

Doc, use the for sale template, you know you want to.
didnt know about that templet
bum bump it will fool mazda if you go for service with them...

what are the benefits of thie 'race pipe'?
Does it change the exhaust note?
Does it just bolt up to the original exhaust setup. So I would not have to make any cuts?
Thanks![]()
Benefits: Removes second cat. ie it removes the second largest restriction in the exhaust. (biggest being the 1st cat/factory downpipe) Car will spool a little earlier/faster, and will have a bit more punch.. Car feels less asthmatic with this bolted up
It IS the exact part you will be replacing.. externally anyway... I have gutted it, and had a straight through pipe welded internally (rather than just gutting it and having turbulent airflow choking up the exhaust path with vorticies as it swirls in the open space of the cat.. sorry im a fluid dynamics nut).. so yes, it will bolt straight up.. no cutting no nothing... It looks identical to your stock piece from the outside.. even the welds are in the stock position.
So no problems taking to mazda for service..
Sound wise.. It made little to no difference to sound.. I honestly say it was less than 5% if anything... I couldnt tell squat difference to be honest..

sounds good.. pictures?
PM's replied..
havent bother taking pics yet.. just seeing if anyone interested..
ill take some tomorrow..
Cheers for the interest guys..
