Re: Engine Mods
Always search because there is a ton of good info archived on here. These things are discussed and debated frequently. From what I have read the gains from the intake are not significant. We have a cold air intake already that does it job very well. Some will advise against it, but I like the K&N drop in filter, just make sure you maintain it properly. I have always used their products and feel that a company doesnt stick around that long by selling a bad product. Thats a whole other arguement though.
Borla seems to be the popular for the exhaust mod. Twin pipes,cat back. I am not sure what your gains are going to be, but opening up the exhaust cant ever hurt.
Also I have read some good things about engine management and ECU upgrades. Maybe someone will chime in who has gone this route. I have not. Welcome. Cheers! 
RE: Warranty. Always check with the dealer first, get things in writing or have them install it.

Re: Engine Mods
I wasnt buying them to increase anything. Mainly cosmetic. Wanted to have a nice soound to the h3 and allow more air to the engine. So anyone who has made these mods give me insight?

Re: Engine Mods
Do a little research on K&N filters and decide if lowering your filtering efficiency for absolutely no gain in power is worth it.

Re: Engine Mods
I've had the K&N on past trucks and just ordered it for this one. There are plenty of people that think they are bad but it you keep them cleaned they are fine. And don't over oil them.
I have a Gibson catback also. I didn't notice any power improvement, but I'm sure it helps a little. It's noisier then stock, but not to much. Almost a little to ricey for my taste, though. I wouldn't mind trying something else.
I got a pcm tune and I did notice the power gain on that one.
All together the truck is noticeable faster.
