Performance Difference. Cat Back VS Turbo Back
Hey Guys,!
I currently have a 3" Cat Back running including a Hi Flow Cat however I left the factory Engine Pipe (If that's what its called
) on.
I was hoping to find out if anyone has really noticed the difference between the two setups?
1. 3" Cat Back exhaust with Hi Flow Cat
2. 3" Turbo Back exhaust with Hi Flow Cat
The car can be quite loud as it is now as well so I wouldn't really want it any louder if you've seen the two did you also notice any sound changes aswell???
Cheeeeers!

Well I believe the only difference would be the downpipe. From what I ve been told the downpipe really doesnt help to much with the hp numbers. I however changed mine when I switched turbos but unfortunately I cant show hp gains because of the turbo and high flow cat being installed the same time I did the downpipe.
