next i needed to add my TXS CBE but the large 4" single tips were not working for me. so i sold my SPT CBE and i bought some dual tip 304SS Magnaflow tips for about $52 each. i cut off the 4" tips and welded the new ones on. i also made sure the new tips where flush with the bumper. i didnt like how the SPT tips where set back about 2-3" and blackened my bumper. i also had to clean the **** out of my mufflers cause their metal is junk and not a true 304SS!!
