Completely normal your going to be hearing a lot of things you didn't hear before.

Sounds awesome! I have Kooks 1" 7/8 LT's with HF cats and a roto-fab CAI waiting to be put in once the weather breaks. Looking forward to the increase in power, throttle response and of course the heavenly throaty sound. Already have the NPP to go along with it all.

I have the Kooks 1 7/8 installed along with the Z/28 CAI and HF Cats plus NPP w/fuse pull. Oh yea does it sound nice!!! In two years purchase a howards LSA Cam and attaching hardware. For now I am just waiting on my Tune.

That's mint!! Good to hear! I did the fuse pull immediately after purchase too. Makes a nice difference. My performance mechanic is doing a tune with mine and putting it on the rollers to see what gains it makes and to dial it in. Any other dyno numbers out there for LT's, HF cats and CAI?

A friend in California did 435/411 tuned last year with a cold air kit plus headers to NPP.

Thanks. I'd be very happy with those numbers for those mods and a tune. Ag1le_Camaro I've seen your videos and pics on Instagram. Awesome car!

Great post you guys! With the Z28 CAI, Headers, HF Cats, and NPP it sounds great. With the tune from Dynosteve it sounds even better

Glad I got a tune along with the install because it evened out the exhaust sound and makes the car as aggressive as I want it to be.

I'll send you a DM. I don't have a page dedicated to my 1LE, thinking about starting one for fun and to share info with people though.

Yeah, that's what I do. I have 3 IG's. One for the 1LE, the second a personal page for family/friends (kid and dog pics!) and third for my small business.

About to install some Hooker Shortys here soon to go along with stock cats and NPP. If I do a cam next I might do a offroad pipe with a high flo cat. I noticed the C6 corvettes have a single cat, I wondered if you only cut off one cat on each side if it would throw a code
