So basically it's better than just having a de-cat... That's cool because i was gunna get a de-cat pipe for £150 and for the manifold as well... and being an ashley to me it's a bargain lol

no, usually a decat pipe is used, goes from the exhaust manifold to the middle section of the exhaust, or atleast mine does, which i wont need if i can get a 4-2-1 |

So if i got a 4-2-1 manifold then i wouldn't need a pipe to de-cat my car i just have to connect the 4-2-1 to my manifold and mid section? |
