I have a 1990 Toyota Celica GT, with the 2.2L 5SFE engine, hooked up to a five speed tranny. I am considering purchasing a set of 4-1 headers for my car. Would this be a bad thing, if I am running on the stock muffler, or would the stock muffler hold back the performance gains in any way?
BTW- would I notice a sound change, if I don't change the muffler?
Thanks in advance
