What Say You Exhaust Tuners?

In two weeks I'll be taking delivery of a 2011 JGC 5.7L, and am considering loaning it to Borla R&D so they can prototype an exhaust system for the new rigs. In turn I'll get a no or low cost new cat-back system or even headers all the way back to fresh air if so desired.

Borla says the factory warranty will stay valid with the cat backs installed, but the long pipe headers on back would likely void warranty and not pass emissions either in Cali or in my home state of Colorado.

Other than being without a freshly bought new rig for a couple of weeks, are there any other potential downsides? Should I go ahead and do this?

Thanks in advance.

Re: What Say You Exhaust Tuners?

I say do it, but i would be just as scared to do it too. But it would be well worth it.

Re: What Say You Exhaust Tuners?

Anyone do a short header, keep the factory CAT, then do catback to keep emmissions compliant?

Or is that just two steps forward, one step back with any gain from the headers constricted by the cat?

Thanks

Re: What Say You Exhaust Tuners?

Moose, I wouldn't do anything that would void your ability to have the vehicle pass the emissions tests. I think you would also be constantly trying to get a CEL disarmed. Unless you are doing all the other engine work that needs the totally unrestricted exhaust, why put yourself through this?

Re: What Say You Exhaust Tuners?

I say go for it! I love my Borla and if you got a brand new custom one-off exhaust from them you would be STOKED! IDK about voiding your warranty this soon (ie headers), but I would def get a custom cat-back. Keep us posted and good luck!

I'm afraid you're right JH. Can't help but look at that lowly exhaust manifold and want to unleash the hounds. Guess it would defeat the purpose if the cat has to stay in the middle of the system to pass emmissions.
