I haven't had my 1994 WRX long, its standard apart from a Down-Cat back exhaust system which is as fat as i've ever seen!, the centre cat is de-catted.

I've got all the service history and it had a cambelt change about 5000 miles ago.

Standard they're are 240bhp?

From this exhaust am what sort of horse power am I likely to have gained.
I did a 0-60 with a stop watch and was getting around 5.2seconds, and my 30-70 through 2nd to 3rd gear was 4.7 seconds, is this about right?

 

i'm guessing it's a 240 BHP. What are the seats like?

 

ER, the standard bucket seats, red and black, very hard wearing thick material!

 

Those power and 0-60 figures seem about right, 0-60 on a WRX in good condition should be between 5-5.5 seconds depending on certain variables.

De cat centre section should release around 5-10 BHP on a good day, down pipe de cat should give another 15-20BHP tops.

 

So I'm probably around 250bhp with the cat gone, and the fact the the new exhaust is a lot larger piping than standard?
Going to decat down pipe then maybe looking around 270+?

These WRX are well rapid on acceleration!!!!

Makes my old Celica GT4 look like an Ice cream van with the gayest music playing and no ice creams!
