i have flowtech shorty headers and the flowtech y pipe. im puttin a cutout on and i want it where the cat use to be but its not a very strait place from the exhaust shops handy work so i dont think i can put it there. so i was going to put it on the strait place on the y pipe right under the passenger seat just in from the ground effect. good idea or bad idea? will it sound bad or melt the ground effect? thanks for the info
