Okay I want to ask you all what I should do. I'm trying to get the SC kit right now and I currently have MXP Double Resinated test pipes and MXP Catback Exhaust. Im not a fan of the sound personally buy I like the extra pull. The SC kits that are out for the car now have the UPREV tune just for the Catback and not the test pipes. So I would either have to pay for a new tune or take the pipes off.
So my question is how much power would I lose by selling the Test pipes after the SC?

 

I'm not sure exactly, but I think the power lost in taking the pipes off would be well made up for and then some by the SC wouldn't it?

 

yes but what would the gains be with them is my question lol. I want to know if the little power is worth the crap sound and $500 for custom tune.

 

wow a lot views but no replies

 

I'm not touching my cats my Catback is already awesome sounding!!! You want power SC is the way to go , even w stock cats I'm sure you will be satisfed.

 

I would take the pipes off and stick with the catback only if that is possible. Have you considered something like Berk HFC + MXP catback setup?

 

have thought of berk hfc and the stock again. i will deffently be putting the tests pipes up for sale and just leaving the stock cats with the mxp catback

 

Another bump

 

stillen doesn't provide a tune for the sc with hfc/tp's and catback?

 

they do provide a tune for them i was not a fan of the loudness is all. I took them off before i got the SC. ANY TAKERS YET ON THESE OR STILLEN INTAKES?
