Hey guys, emissioni s coming up next month. I am ready to order a new cat. Currently I have gutted pre cat and a gutted cat on my 90 GXL. I am currently looking at either the Bonez cat with pipe (315) Mindtrain cat with the pipe (399) or a Mindtrain Header/Test pipe+a Random Technology cat or something (500)? Which one will be give me the most hp, the header/cat combo will probably do me really good, but it's kinda pricey. What do you guys recommand if i dont go with header, mindtrain or bonez? Also what is the noise like with the mindtrain header and a cat? I have RB Mufflers
