Just bought a deCat 2half-inch middle section off eBay for my 2005 WRX.
I now need to know what I need to buy next.
First of all as the lads' car selling it was an 03 WRX, so I assume the 2half-inch is the right size for mine. If so, as I understand it, I now need:
1. deCat Up pipe (not essential tho?)..
2. a de-Cat downpipe.
3. SS de-Cat front section pipe.
Can I get away with changing the last 2 to get the required extra 30bhp before remapping (if so, know anybody who's selling..) ?
I'm also assuming (I know, I know) that the backbox thats on my car (this 4-5" monster thing that was on when I bought it) will simply attach to the new decat middle section Ive just bought.
Also come MOT time, should I expect to change any of the above or will it perhaps scrape through..?
many thanks, Steven
