OK i have an LBZ and i want more whistle out of the exhaust. I do not want it to be more throaty sounding just more whistle. I heard an LBZ on the road and all u could hear was the turbo singing. Any ideas?
One of the things that can make the turbo whistle better is an aftermarket air intake. With our experience that seems to help create more turbo sound, which would work really well with your 4" exhaust you already have.
AFE makes the Stage 1 or Stage 2 air intake systems for your truck and I think it could help with what you want, plus it will give you better performance as well. Just a thought!
Get the cat back system from MBRP, leave the cat alone and the overall cruising sound level will be nearly stock, only when you wail on it will you hear it "talk". We have sold a lot of folks this same set up and they all say it's sounds great when they want to hear it but otherwise it's stock. Plus you get some HP , some EGT drop ans turbo spool up too!
Before you run out and buy anything I would suggest you find other members who have already modified there trucks and see if you can listen to them. It's one thing if your going to run around empty but if you do a lot of towing the deep tone or mellow rumble will drive you nuts in the truck. Our exhaust kit is near stock noise leaves with a little more tone on the outside but the in cab noise level is no louder than stock. You can find them on our web site.
