Coverage and how to read this overview

Counts describe captured discussions, not unique people or a diagnosis. Author identities are not reliably stored. Exact duplicate evidence is counted once across matching discussions; one discussion counts at most once per action/state. Multiple repairs reported together remain a combination. Suggestions and failed attempts do not establish a fix. Matches cover whole discussions and can include related faults, model variants and incomplete threads.

11 eligible posts · 0 unverified posts · 1 discussions match the subject in their title or opening post.

POST 1 / ORIGINAL POSTEROriginal post

Just installed Fabspeed muffler bypass pipes on my 99 C4. Other than being louder are there any sort of drawbacks to running these pipes? The sound is very agressive.

POST 2Original post

Quotes source post: 5964498

Terrible low end torque. Makes sound system upgrade worthless. Makes horn a second choice. -td

POST 3Original post

Next mod is a choice.... ear plugs -vs- going deaf

POST 4Original post

They did take away some of my low end torque. I don't race my car, just use for a weekend vehicle; so I really didn't care that much. It is still as fast and strong as I need it to be.

POST 6Original post

They actually don't drone very bad on the highway at all.... for a system w/o mufflers. I'm taking them off of my car for now as they sound terrible with the top up - most definately a mod that I would steer away from if I had a hardtop. It's just too loud inside the car with the top up.

POST 7Original post

POLICE...you get to learn how to roll by them without giving any throttle. Everyone wants to race you... BTW...I love mine

POST 8Original post

This probably isn't much help, because when I had mine on, I also had cat bypass pipes on as well. It was one of the dumbest things I've ever done. Just too loud. It had to scare the crap out of people as I passed them on the highway. I had them removed the following week and sold them. It was entertaining for about a day though. I would honestly spend the extra money and get a decent set of mufflers. Just my .02

POST 9Original post

will wake up the whole house, sneaking out... on those early morning drives.

POST 10Original post

Had them, loved them and hated the 55lbs of torque I lost on the dyno. However, they still sit in my garage on the shelf for that one day when my neighbor glares at me again. He has no idea how bad his morning coffee could get. And they drone like crazy.
