Cheapest exhaust system fitting a stock gsl-se. Is Mazda Trix about it? Trying to not go back to the trio of catalictic converters from Mazda for 1500 bucks. Mazda Trix has a header and primary converter replacing the trio of converters but its still about 700 bucks. Is that about the best one is gonna get fellas?

 

You can save a few dollars and keep your current exhaust and use one of these catalytic converters. I have one on my street exhaust bolt-on mid-section that I use for inspection time.

You'll need to remove your current mid-pipe section and have a muffler shop cut the old out and weld this in place.

 

i guess i should have mentioned that ive taken off the 3 converters, and have thrown them away. and then found out how expensive they were and tried to get a piece of pipe cut to fit with flanges but am told its illegal and dont know where to look. I dunno.
