FRPP Touring are Too Loud

I installed my new FRPP Touring mufflers two days ago. I picked them since they are reportedly the quietest quality aftermarket item.

They sound simply awesome rowing through the gears, not too loud or quiet, great high performance throaty tone. However they are too loud on the interstate. They get noticeably louder 2200-2800rpm, which with my 3.73 gearing, is 65-85mph. I guess I'm just too old, so the stock mufflers are going back on today.

They'll be posted for sale soon.

They will break in and get a little quieter at cruising. I felt the same way at first was annoyed on the highway. After 1000 or so miles quieted down.

I have have a stick with 2.73 gears and found it is louder in 5th and 6th at low rpm's around 2000, if you avoid the bad resonance rpm they are quiet even under load on the highway.

So what I try to do if I am on the highway with some traffic I don't let it get under 2500 rpm.

Too loud is certainly subjective, but I have Borla Tourings installed (from what I gather, the same as the FRPP Touring) and I don't find them loud at all. No drone on the freeway, nothing objectionable to me at least, and I am running 3.73s also. I get more noise transmitted from my DS, but even prior to it's installation, I found the mufflers to just about perfect for my tastes.

Sorry they didn't work out.

I would give then more time. Mufflers will quiet down a little over time.

Well if they are awfull I could probably find a use for them and take them off of your hands ... just kidding. From what I understand there isn't a quieter after market muffler and the Borla Touring's are a straight flow through design vs the FRPP touring's baffled design.

I know this sounds like an odd question, but you didn't get the ford racing mufflers intended for the GT's did you or maybe not get the clamps seated all the way to the over axle pipes? Those are both sources for noise. Just trying to help out.

They are now listed in the for sale section with photos, thanks all.

I really loved the way they sounded when ripping around, but are just too loud for a daily driver for me. Considered trying just one but it wouldn't look right.

I'm taking a 4-hour interstate trip this weekend and the stock mufflers will be perfect for that. If only I could just push a button and switch between the two.....

I don't think there's room underneath for two sets of mufflers. That would be an outstanding solution!
