I have a '03 Lightning and was wondering what exhuast system would give me the greatest HP gains with good sound thats close to stock sound.

Thanks for any help guys

 

Magnaflow would be your best bet.

 

Full exhaust ie long tubes, hi flow cats(maggie) and maggie catback.
A good one is the dynatech long tubes and high flows.

A catback only just makes noise.

 

So which would give me the greatest Horse Power Gains?

Im looking for somewhere around 10HP+

 

None.

 

+1. Unless your pushing above 480-500rwhp then your wasting your $.

 

HP gains are not the reason to do a catback, do it for more volume, Magnaflow, JDM's silver bullit, Bassani are all solid and should fit the bill, long tubes, high flow cats and a catback on a bolt-on truck should get you 15-20hp add more deeper mods(heads, built motor) add more gains, just don't expect a huge gains, it does sound bada** though T

 

OK thanks
