Flap is now clamped open and I had the resonator chopped off just now. I'll write up a review soon

drove from the muffler shop back to my house ~10 minutes on city roads, no highway. BUT I LOVE THE SOUND NOW! removing the resonator and opening the valve sure did cause a significant increase in deep, grumbly sound. Can't say anything about the v4 noise cause I haven't driven on the highway yet for it to be noticeable. but omg it sounds delicious, like a v8 ~~

might go get a tune doe. after chopping off the muffler, resonator, and opening the valve, the shifting is a bit off? higher revs before shifts

Hell ya man let it rip now!

I have a diablosport trinity and it improved my truck greatly! You may just be noticing it hanging onto gears longer before shifting now because you can actually hear it lol.

Probably not a bad idea to pull your negative cable off your battery for a couple minutes and then drive it hard after to get the computer to relearn your driving. If you drive hard during the learning period it tends to have better throttle response and shifts better.

whats your opinion on the Diablo Sport intune? and does adding this void warranty?

Its the same thing as the trinity, you can log more and do 0-60 etc with the trinity.

You back up your stock tune before installing a custom tune so you can return it to stock if you ever need to take it in for warranty work.

Dealership can still count how many times the computer had been flashed though

actually before the tune i want to add the airaid jr kit. i see that you made your own pvc pipe. is there a way to convert the airaid kit to 4.3l v6 version?

I have a 4.3 with a super 44, flapper is off and the resonator is gone. I liked the sound and the drone wasn't bad at all in my opinion. I added a cold air intake from Injen technologies and it really changed the exhaust sound around 2300rpm to 3000 rpm. Exhaust sound is a tricky situation because everyone has different opinions on what sounds good but with that said I really like the way it sounds. Not loud going down the highway or around town unless you get on it

I had my corsa sport put on at a local exhaust shop and they left the resonator/3rd cat, would it be worth taking it back and having them remove it?

Some people are calling it both the 3rd cat and resonator like it's the same. There's a 3rd cat towards the front behind the other 2 cats and then the resonator is basically a 2nd muffler that you see at the rear axle. I left my 3rd cat on but had the stock muffler and everything behind it taken out. If you want it louder then get the resonator taken out. I may take my 3rd cat out one day but it's no rush since my truck is plenty loud and I don't think removing the 3rd cat would do much.

I can't get good sound out of my iPhone mic, and can't do it in the driveway cuz the neighbors already complained about my roommates exhaust (straight piped with no cats lol). Anyone have any suggestions to get good sound quality?
