What are you going with since you're not doing true duals?

 

What happened?

 

14 inch si/do magnaflow

 

Don't worry man... It's a good muffler. Later this week I can give you feedback on hi-flows... you will be happy

 

Thats another thing I have learned , the cats we call hi-flows aren't really hi-flows. There just a shorter cat.

 

The 05+ 2 cat system flows much better than the previous 4 cat systems that had a little packing to them and longer catalysts. The shorter body does help aid in the volume though. Since your coming from a 4 cat system you will definitely see the difference.

 

They do flow better than stock though. The ceramic brick does have larger holes in it.

I thought you were going dual bullet?
