By far our most popular exhaust, the Magnaflow 4" is a great free-flowing system.  Benefits from installing include - Lower exhaust gas temperatures (EGTs), Faster turbo spool-up, better boost at lower RPMs. 

The system uses a straight-thru muffler, and also features -

• Complete Turbo back stainless steel construction
• 3.5" Down-pipe with 4"pipe to a monster polished 5" tip.
• Gains 15-18hp and 40lb./ft of torque over stock system
• Easy installation - uses existing hangars

Magnaflow exhausts let people know you've got power under the hood.  They have a smooth, deep tone at idle that turns into an authoritive growl under acceleration.  Simply put - the system is awesome!

We now offer the Magnaflow XL series exhausts as well.  If you're looking for a lower-cost stainless steel exhaust system, this one is for you!  The XL series features all stainless mandrel bent tubing, and an aluminized muffler.  We include the 5" stainless polished tip for free.
