Default GT haus mid pipe

hello,

Installed the GT haus midpipe several months ago (with stock mufflers). While I really love the sound (esp mid range), there is a mild drone at low speeds that is intolerable to some of the passengers. The midpipe eliminates 2ndary cats, so I am wondering adding aftermarket cats would address this, or adding a resonator?

Thanks in advance,

BK

I have the same version in Titanium. The midpipe eliminates the factory secondary cats and resonators. I would just sell it and buy the Apexi resonated midpipe or tell passengers too bad haha.

You could add resonators too. I’m a fan of the sound. Also running Toms Ti axle back. It sounds glorious.

What was the purpose of installing mid pipes on stock mufflers?
I'm just curious.

Produces more sound than stock, gets rid of secondary cats and resonators.

so I have a gt haus mid, paired with Greddy axle back, its loud in a good way...had it last 2 years, recently put a Toms axle back.
I dont think it made it any less louder, maybe just deeper.
Apexi resonated mid pipe is little louder than stock, some say its too quiet. I know the "drone" you are taking about its at low rpms and goes away on cruise but not enough to bother me. Its not a Daily and I appreciate the exotic sound.

do you have any sound clips by any chance? I was thinking of running a similar setup as I think the all gt haus cat back may be too loud for my liking.

Anyone know how the full Apexi res catback sounds (with the Apexi axle back)? I've looked around but don't seem to find anything. What I have found is the Apexi midpipe with different axle backs. Thanks.

We'll have a local customer get one installed soon, I will try to record something.

We can do custom orders off the website for a GSF midpipe that will bolt you your OEM axle back. Or you can do the complete set and shut the valves to be quiet. Our prices are very reasonable. PM me anytime and I can give you pricing.
