JBL shorty headers

Reviewed By Robert M (COSTA MESA, CA) Reviewed for a 2007 GMC Sierra —3/12/2018 10:40 PM

Started with a K&N cai with a throttle body spacer from airaid. Gave it a nice throttle response. With the JBL shorty headers it helped with some top end hp. Sound didn't change until I got a free flow magnaflow muffler. Now it has Alot of top end power. Very happy with everything. V6 4.3 need all the extra hours.

Great sales experience on a quality product

Reviewed By Daniel F (North Las Vegas, NV) Reviewed for a 2010 GMC Sierra —8/14/2017 1:33 PM

Quick delivery of well packaged product. Instructions about preparing to install the headers were great. Complete project took about 6 hours and I was not hurried. These shorty Headers gave my 2010 6L GMC 2500 exactly what I was looking for... about 10% better fuel economy and 5% more mid-range power while towing my RV.
