I plan on doing an ls1 swap into my 89 chevy truck and I was wondering whats a good muffler to run with it? I wont be running a cat and will most likely be running headers. I also need the muffler to be fairly small because I only have about 4" of clearance for it. I have some flowmaster 40s but ive heard that they are rather loud. Im looking for something right in the middle
thanks
Jim
