need to know the truth
im looking to put headers, high flow cats and y pipe on my 99 t/a. i have slp's loud mouth cat back on it now. i i was going to complete the system with all slp stuff b/c o i love the loud mouth system, but i was told that there exhaust systems have problems and the quality isnt that good. if this is true i was going to go with a MAC system. which would i have better luck with.
