cant really do research on it. all i know is its a 3" TBE with 2 cats both 3" in/out + muffler. can i safely assume it will increase my hp?

 

2 cats? Is the exhaust system different over there than here in the U.S.?

 

It's probly one cat and one resonator.

 

yeh we have different EPA standard and noise level. i believe its 2 resonator + cat + muffler. either that or the sales guy is saying 1 resonator after the turbo, 1 cat in the middle and 1 muffler at the rear. so my question still stands, if its a 3" TBE, will it increase power as i already know it will give out faster turbo spool

 

Yes. Not much more, but yes you will have a slight gain. Go for it and be happy.
