Ok I know that I would like to get a hytech header but for the catback exhaust what do you all recomend. Do you all think that I should just get the catback that john sells with his headers or do you all think that I should order a 2.5 catback exhaust from kteller (I want a hytech muffler so I wouldnt get that from him). Which do you all think would be the quietest and perform the best. I think that if i got ktellers exhaust it would be a little bit cheaper though.
