I have read a lot about them here and in andren foren. positive as well as negative. but what my opinion speaks very much for heico is that my extension of the new car guarantee does not expire. and that’s very important for me. I don’t have a buck to destroy my car by “cheap” tuning. I have now asked at heico a stainless steel exhaust and an andren (without volvo designation) cooler grill. result: ca. 300 euro for an unpainted chiller grill ca. 900 euro for stainless steel exhaust with tüv review (fürn volvo c30 2,4i) and the prices have surprised me very much. I am a trained metal builder and for the 900 euro the exhaust can only be murgs.des can not work! or is it a product from far east quality and also the price ratio between a cooler grill (unlacquered) and exhaust (sold steel)????
