My Truck Still feels chocked up?

[Annu Kumar]

ok guys After stage 2 Flash, K and N, the truck pulls hard. But It still lags a little bit. Please tell me the Belanger Headers and Catback Exhaust will make a huge difference. I mean Is the Exhaust system that Choked up? Like For example I assuming the guys without no Exhaust upgrade you guys feel That sometimes when you hit the gas It feels something is holding it back.
By the waymine is a 06 Qc. Thanks guys

I did notice on mine that the mid-pipes opened it up extensively... our stock cats are realllllly restricting...

I have an '05 quad cab. The exhaust upgrade was a consistent improvement of .5+ seconds in the quarter. Yep, really made a difference. Best run prior to the exhaust upgrde was 13.363. Best since the exhaust upgrade in not as good air is 12.820.

How do you lose the Cats Here In Cali. Ok How much horsepower will a good cat back with Mids put out. And How much Hp will the same set up have with no cats at all.

You either keep the stock mid-pipes and cats, and with a Magnaflow... thought debated, you should see around 10-12rwhp... though they advertise much higher...


If you go with mids, and take out rear cats and Magnaflow, I would say that you you will get about 20-22rwhp.


And finally, if you go mids with no cats, and Magnaflow, you should see 25-30rwhp, and a whole different sound.
