I got the Tomei supreme ti exhaust for my 16 370z nismo, not a cat back as it didn't come with the y pipe so I wasn't able to bolt up the exhaust as the stock exhaust is a true dual with an h pipe, would getting the Tomei y pipe fix my issue? Pictures are of the stock exhaust, and the last one is of the Tomei cat back, including the y pipe obviously. Just wanna make sure before I spend some more $$
