Hey guys,
I was thinking of doing this mod to my car, but am wondering how loud would it be? Anyone in the Doyelstown area with this done so I can listen to it?

I was looking at the videos online, but i cant seem to find a good representation what what i really sounds.

It will be very loud. If you daily drive the car, it will not be pleasant.

Here is the similar question already answered.

As I said in that thread, drop your mufflers and put $10 autozone pipe to get the idea about loudness and if you can drive with the noise.

Mine is pretty loud, but I don't daily mine so I enjoy it when I do drive it.

Besides being loud, does it sound like a Chevy without a muffler or does it retain some of the flat six sound?

I ran the muffler delete pipes on my C4S for awhile. It sounded AWESOME, but was just way too loud for me. 15 minutes on the freeway and the droning would give me a headache.

Imo000, it still sounded very much like a Porsche, just really loud with a pronounced rasp (the good kind of rasp).

I like the way it sounds, and you do get a bit of that flat six sound but it is in fact loud.

I think that for a daily the Muffler bypass pipes are FAR too aggressive. Sound is a very subjective thing, and some people love them on the road but I would say that the majority of my customers go with a less aggressive set up.

If you are in D-Town, you should stop by Fabspeed ANY time and you can check out our facility and look at some of the other options for your car.

dont do it.

Have an exhaust shop that does custom work do the fister mod. Subtle at low RPM but sounds awesome at WOT. Best $60 I've spent.

Besides personal preferences, you may not be able to participate or enter some track events depending on venue/rules.

My supercharged 928 doesn't have mufflers or converters and I like the sound. If these bypass pipes are as much or less loud, I'm ok with it. I've got a used pair in the fall that I'll be putting on when I have to pull the mufflers for the vario-cam solenoid replacement.

Thanks for the reply guys.

I am looking for something to bring this car to life! I feel it is nice under WOT, but really want that aggressive sound. Being a car enthusiast, I don't mind a loud sound, as far as it sounds pleasing.

Capt. Obvious

Honestly, if you want to know what the bypass pipes will sound like before you spend the money, take the 20 minutes to remove the mufflers and go for a drive around the block. It will be a bit louder in the car than with the pipes since the noise will be bouncing around the engine bay instead of being directed out the back of the car, but the sound will be about the same.

I was clocked multiple times at an SCCA event (around 30 feet is the distance I think) at 99.7db. The limit was 100db. They do sound like a rocket ship at WOT though.

another option is fabspeed supercups...it's about 80% loud of muffler bypass
