I went with the 3" down pipe as well as the lb7 style up pipe for my 06 lbz.
highly recommend the up pipe, much better than the block off plate.
paired with the 3" down pipe is a must, I can tell my truck is building boost quicker and getting the exhaust out faster.

Simple install and works great

This was a super simple install. Took about 45 minutes, which includes removal of old exhaust. Exhaust fit well and seems to be made of high quality. Truck sounds awesome!

Exhaust fit great, great quality, sounds great, used with the muffler and is surprisingly quiet! Will be ordering more in the future!

Buen producto buena calidad

This is very good quality and the shipping was very quick. Definitely trust this site and will do business with SPELAB again.

Customer service support was great, and the product worked as described and the extra heater hose included was a life saver in helping me fix my HVAC heater when the factory connector broke.

I am happy with my purchase. Looks to be a quality part, and definitely can’t beat the price .

Looks pretty%2C install wasn’t bad other than the very last fuel line which isnt spelab’s fault lol%2C i find that the turbo spools faster and power comes in harder. Less black smoke now that she can breath%21%21%21 Overall very pleased%21%21%21

Had it installed on my ‘99 Camaro Z28. Sounds really nice at WOT, and the tone is very deep at idle. Was decently made, electric motor has held up nicely from water over the past few months. Wireless fob has better range than my cars keyfob lol. Assembly was straight forward, but there were more parts included than the instructions had said. Would buy again for another vehicle with a v8.

I love this product. Easy install. All hardware was perfect. It’s a beautiful product and has qualities that I love. Fill and drain plugs and mostly the sight port.

Awesome product and very easy to install also the best part about this kit is that it does work with other added on fuel filter AFTER the cp4 so you get best of both worlds🙏🏽

The 5' exhaust with the 6" tip looks and sounds really good. The egr delete its made really nice and fits perfect and looks good.
The ccv it's easy to install it fits and looks good too. Thanks soo mutch

It works great, the nut that rubbed a while in the up pie was moved from the original place and doesn’t rub anymore

Not to easy if you don’t know what your doing\not mechanically inclined, but definitely worth it for the quality love the stuff!
