Nice Sound

Once i got the cat cut off it was easy 2 install. Took about an hour. Truck is alot louder and the turbo spools alot faster. Sounds good

Front Pipe

This is a great addition to your cat-back exhaust. Removes cat and opens up the exhaust for an awesome turbo wine. So easy to install, installed this in my driveway in 15 mins. Every diesel on the road should have one. I also talked to the Chevy dealer, it is totally road legal as diesels do not require emission testing in PA. Don't forget to block your egr and install a "finger stick" for added performance

MBRP Front Pipe (Cat Delete)

Best bang for the buck. Took about an hour to install on the driveway. Immediatly noticed on first test drive that it took away the throttle hesitation, it's way more responsive now!! Noticed it allows the turbo to spool up faster, you can definatly feel the increase in performance. On top of that I'm averaging about 2 MPG more per gallon!

Front Pipe Addition
Anonymous (Unknown) 5/1/2008 10:01 PM
I just got done installing the front-pipe into the exhaust system. I was able to modify it a little to fit the Banks Cat-Back system. Immediately I noticed the faster spool up time and the increase in power. However, the best noticeable increase was in the fuel economy. I had a PPE tuner, Banks intake, and Banks Cat-Back and was getting 16.8 mpg. Now with the addition of the front-pipe, I am averaging 21.1 mpg!!! Definitely the best upgrade to buy for the price! I recommend this to all diesel truck drivers.
