C7 pipe

[Steve Megill]

My c7 has 495 hp-517 lb torque because of afe intake and performance tune.Would x pipe make that much difference

Just the x-pipe alone ... nope. I assume that hp and torque rating is at the engine and not the wheels.

Agree with Tyho. X pipe will not likely make a lot more difference.The C7 pipes are pretty efficient. Headers, cat delete and a custom axleback (Corsa or equivalent) will give you another pretty good bump. After that, next jump would be a cam, but that's $$$ once you start on the internals.

Agreed. I've had quite a few mods done to my C7 (no cam) and with all of that I got to approximately 535 hp at the flywheel (465 hp at the wheels). You loose about 15% hp to the wheels. The stock C7 comes in at 460 hp (400 at the wheels) so your 495 sounds about right with your current mods and tune.

If you are up to sharing, I would love to see your Performance Mod list and where you had the Car Tuned.

Having something similar for next Summer would be great.

Dave at Race Ready Garage did most of the work on my car, including the tune. Without being biased, I honestly think he is one of the best at tuning and his work is first rate. Dave has the figures from the dyno if you are interested. I think he did post them here quite some time ago.

Car is a 2015 M7 Z51
ARH mid headers with high flow cats
Borla catless x-pipe
B & B Bullet exhaust
MDS intake manifold
Trunnion upgrade
Innovator West light weight balancer
Katech light weight flywheel
DSS carbon driveshaft
LG GT coilovers
Halltech carbon cai
MGW shifter
Low resistor plug wires, heat shielded
Braille light weight battery
Carbotech 1521 brake pads
AFM and NPP actuators removed, NPP valves removed
4 cylinder mode tuned out
1-4 skip shift tuned out
Tuned
All in all, the car is about 100 lbs lighter and gained about 75 hp.

I think that's it. Can't remember anything else other then a few minor cosmetic items.

Awesome, thank you.
I have heard many good things about Dave @ Race Ready.
