I just got my sp2 put on and im wondering if i need a hi-flow catalytic converter with it?

will it increase power at all? considerably?

and will it make any difference with the sound of the exhaust?

thanks!

 

I don't think the hi-flo cats give much HP. I have a high flow cat and didn't notice much change. I changed the Y-pipe and noticed a big difference.

 

get sound clips and pics if possible cause i want to know how it sounds and look before i get it.

 

I think CustomMaxima.Com has a sound Clip of it

 

sounds really good! not too loud at all... it looks very nice too

 

niiiiicce.....do you have any pics of this setup? I'm kinda getting tried of my WS and looking for a different setup.

 

yes.....your car/exhaust will sound a lot louder.....and if you get a y-pipe later on, it'll be disgustingly loud. might even get bees in the can like i did. hi-flow cats are a waste of money and only gives you 1hp.

 

do u have an intake? get an intake and y-pipe. then go for UDP.

 

mike sounds great ! how much did the sp2 set you back ? any idea how wide the muffler tip is ? i have the sarona rear and not sure what will fit through it. will have to measure. anyways good deal ! bet its sweet

 

Don't get a UDP, get it if you don't mind extra vibrations from the engine.
