Played around with the exaust today. Some general thoughts

Nele22 · 03-10-2011, 08:12 PM

I installed my cheap test pipes first. For clarification I already had the cheap y pipe. After getting the demon bolts out I drove around with the new tps. There is rasp and it's not the best sound. Kind of like a tin can. I wanted something deeper so I wen back to the shop and pulled the stock muffler. Left the rear pipe open. Drove home. WAY TOO LOUD! It hurts. This from a guy that ran the muffler delete on my c6 corvette. I think the tp and muffler delete is just too much.

Tomorrow I am going to opperate on the stock muffler. Cut it open, gut it and bolt it back up. I am hoping that the hollow muffler will tone it down a bit. Thoughts?

I doubt the gutted muffler will tone things down all that much.

Jordo! · 03-10-2011, 08:23 PM

Gutting a muffler will make it louder...

I doubt much of the noise is coming from the Y pipe -- probably all from the TP's.

The OEM set up has a bunch of counter weights and metal shields and brackets that help cancel resonance.

Nele22 · 03-10-2011, 08:35 PM

I hear ya. Just wondered if the gutted muffler would be quieter than nothing back there at all.

christian370z · 03-10-2011, 08:39 PM

Nope, it would be a waste of weight, time and money. You can get a pair of Vibrant 18" resonators which would tone both the volume and the rasp down for a reasonable cash outlay.

I have...

Stock Cats
Cheap Y pipe
Stock resonators
Muffler delete pipes

It's louder than most cat backs, however the sound is deep and throaty... not raspy at all. It is just enough to give it a little gurgle...

I have been toying around with the idea of test pipes but I don't want it to be extremely loud.

This pic was taken from Kastley85891 after he gutted his muffler

So, looking to cover my costs and time, it currently is fitted with 2 90 pipes internally, it did free up some top end for me power wise via the ole butt.

What was removed.

hope that helps a little. maybe he can provide some insight

I spoke with him last night. With the muffler gutted and TPs installed it was very loud. I decided to bolt the stock muffler back to the car.

Has anyone removed the resonators before the muffler?

antfd3s · 03-11-2011, 09:15 AM

Your going to have rasp from non resonated cheap tps. Now you wanna gut the muffler? Im thinking thats only gonna give you tons more rasp/ a loud ricey note.
So i have some thoughts! lol.
Id put all your original stuff back on or at least keep the OEM muffler stock till you look into a cat delete. AAM Competition short tails looks like a good redemption idea? Considering i see the route that your trying to take. Either way, I just hope its clean and non raspy. I give props to TypeOne, he made it work.

Nele22 · 03-11-2011, 09:38 AM

Not sure what you mean by "I see what route your trying to take." My thoughts were to play around with the exhaust and see if there was a cheaper solution to the quiet stock version.

I plan on ordering some resonated HFC and a Cat back as soon as I decide what I want.

Nele22 · 03-11-2011, 09:39 AM

Stick with your current set up. With the Y and muffler deletes the TPs will make it unbearable. This coming from a guy who LOVES loud exhaust.

Oh sorry i just posted without knowing your gonna keep your stock muffler. Ok good idea, Now. Removing your resonators along with having a stock muffler? I think thats not gonna get rid of your situation. Resonators are good to have with toning down drown/raspyness. Removing them only will increase flow into your stock muffler. Generating more obnoxious sound. Id keep the resonators. imo

Right. You dont wanna spend a whole lot of money just to get the sound your looking for. This is just a meantime setup to hold you off.

Don't fear the loud exhaust, the VQ sounds awesome when full freed
