Hey Everyone,
First post here, have a 2006 Mazda 5, starting to mod it as much as possible w/o turbo, went to a Midas to check the exhaust and they told me that not too much can be done, is this true? Looked for a c.a.i. had to go with one for a 3, works well, but what else can be done on a budget. Any advice is welcome. Mazda 5 2.3L
