Very impressed with the Corsa cat back and CAI. Cruising inside, almost forget it’s there. Outside is a different story. And those cold starts are brutal

You getting that? lol. Shoot I know cold start damnit hahah I need to post. Will try soon
On the fence this moment on the TB. Have used shorty as well as full headers in the past (on RSX pre-boosted) and shorty didn't yield much difference via butt dyno. Watched a video review of their BBTB and they didnt notice any "real gain" until tuned to allow more air flow. Which I guess could make sense in theory. I remember back in the day taking off my stock TB and taking a Dremel to it to open it up....which was apparently wasted time since not consistent. A for effort right :elephant:

hahah yea. i mean its still a nice bit of money for the TB. I honestly would say I do feel a difference when I accelerate. But it can be a combination of headers, intake and throttle body all working together. If you were in Los Angeles area I'd have you take my truck for a spin to see any differences you would feel

Sounds a bit deep than stock; from headers I'd assume. You need a Corsa THEN do the in parking garage cold start :party36:
Probably headers and the magnaflow muffler. But considering swapping to a MBRP car back lol

Okay I just changed my muffler to a borla pro xs and have to say this is the best mod I’ve done to the truck. Sounds like the V8 is supposed to sound. Highly recommend for anyone looking for a deep growl and no drone.

Hi All!

Pretty new to the forum and wanted to get some sage advice from everyone here.
Currently have a Magnaflow muffler and KN CAI on my 6.2 V8.
I'm looking to add a couple more mods and these are what I have narrowed down to:


BBK Shorty Headers 40480​

Soler Performance 87mm/91mm Effective Bore Premium Throttle Body​


Does anyone have experience with these parts? Are they worth the investment?
Thanks all and cheers!
I recommend adding a supercharger and you should be conyent for a long time. Definitely the best bamg for the buck.
