Ktec sports cat and piper cross panel filter

[02teasda]

Hi, I'm getting a ktec sports cat and standard centre and rear exhaust fitted to my 172 cup tomorrow. I put a piper cross panel filter on last week and already the car feels so much smoother and sounds better.
Couple of questions though:

What kind of gains can I expect?
What gains with a remap aswell?
Also theres a thread in the ends of the exhaust hanger brackets on the exhaust itself as though something screws in? Does anyone know what these are for?

Minimal gains. Pay it if it makes you happy.

threads are for screws.....

would have been fitted to the original exhaust and should have been saved and reused

If your car had a dirty and half blocked up standard filter (which it probably was if it was making the car drive badly) you'll see big gains from a new one, standard or modified.

Thanks guys took it to an exhaust specialists to get fitted anyway so they had the screws to go in the exhaust hangers. The exhaust sounds so much better and I can't believe how quiet it is! But.... Now it sounds like my dephaser is on it's way out

Anyway if anyone is after a cheap second hand aftermarket exhaust check out my listing on eBay for the old one. No idea what make it is?!
