Yeah I would but I dont have the extra $350. My 3.5 inch high flow cat is costing me $480 installed. Will do it later. Hopefully the tune wont be as much then as it will just be a retune

I would personally get injectors before you get a cat. Safer having the restriction being the exhaust rather than the fuel system.

To be honest, IMHO the cat is a waste of coin without the injectors in place.

Get the injectors in first and when you get the cat installed later you may just need to get the tune checked. If you do injectors later you will definitely need a retune to make them work properly.

Torque delivery will play a large roll in wether the clutch will hold or slip, also how the dyno operator loads up the dyno.

My stocker was fine for up to 300ish, but it depends on if you've given it a hard life and glazed/burn it befor hand.

Hey I just realized I made that piping for a guy in WA a few years ago... one of my very first piping systems for BA's, first one I sold too.

I think he had low 300s with it.

You should make 260 max on stock injectors, and that's the limit.

If you want anymore power the injectors need to be replaced, then you can go for more... Ive seen up to 300 through the stock BF cat with my bigger cooler kits, so it might come close.

Put a better flowing cat on, and it should go over 300.

SennaT has pretty much the same IC & piping set up and is making 340 with an exhaust.

And the torque and response is miles ahead of the stock cross-over - me likey!

Went to have it tuned yesterday and after putting it on the dyno they told me to do injectors and fuel pump. I didn't want to at first but am going to now. Car was making 295.2rwkw but the injectors and fuel pump need to be replaced so they can get more power out of it. At the moment its back to stock tune until I go back to have a custom tune in a couple of weeks.
