FRPP X-pipe vs. Borla Resonator Catback W/Headers (Videos)

Had FRPP Touring by Borla catback and thought it was great. Then added Kooks catted headers and it brought out some rasp. Bought the Borla resonator to quiet it down and it did. A lot. Inside I can barely tell I have exhaust even with the headers. This is way to quiet for me but wanted to show the comparison for others. I'll try to get an in cabin video but it might be silent...

Great job with the videos!

The mid-muffler/resonator definitely made a huge difference. I prefer a sharper exhaust note but that does sound very nice overall.

Thanks, so much is preference. I want something with the tone of with the Borla resonator but much louder, thought the headers would get there but still too quiet. Looking at louder axlebacks to pair up with the resonator, anyone know if that will make much of a difference or not really?

Here's some in cabin revs and WOT 1st & 2nd gear. Windows up then windows down.

Try Borla Atak axlebacks. You could sell the Borla mufflers you have now pretty easy if you like the Atak's.

I'll add them to my watch list. So do you think changing mufflers alone will make a significant difference (I'm assuming axleback and mufflers are the same)? I'm still trying to learn exactly what each part of the full system affects the overall sound. That resonator quieted down everything way more then I thought.

very nice

My ears enjoy the Borla the most TY!

i have the same issue lol..It rasp like crazy. I have the frpp sport with SW headers. Im planning on going with SW catback.

Borla touring with the kooks sounds amazing! Do the kooks require a tune with highflow cats?

I was able to use the same Lund tune from my intake and exhaust to adding the catted hi flow long tubes. Still way to quiet for me but going to leave it for the drag tonight and road course next week then probably add roush axle back. Would like to test a sport exhaust so there's no cutting but pretty hard to do that.

Thanks for posting this! I have an S-Type catback, but was a little hesitant to add headers down the line because I thought it would be obnoxiously loud (I was actually looking at Kooks catted headers as well). Looks like I'll just buy the Borla resonator if it's too loud for me.

Now if I can just get over my hangup about tuning a car that still has a warranty... (and the cost and hassle of installing headers...)

[MENTION=13650]Mark5825[/MENTION] Where did you buy the resonator? I have your exact same set up - Kooks Green Catted Headers and Ford Racing Touring. Its way to raspy and annoying now.

I'd like to go for a deeper tone at a few decibals lower. However, it seems that the borla resonator is too quiet. Any other options you'd consider?

If I were going to do it all over again, I might just leave the stock mufflers and spend only $50 to $75 on having the resonator replaced with straight pipe at a local shop. I went the other direction:

Flowmaster 40's welded in. Deep, but too quiet.
Replaced resonator with straight pipe. FFS, it's louder than a 505 now.
Put the resonator back on while awaiting an X Pipe.
This, too, will probably be a mistake. We'll see tomorrow.

Meanwhile, the best sounding S550 that I've heard thus far was one with stock manifolds, stock mid pipe and a Ford Racing cat back. Deep. Loud but not obnoxious. No drone.

My two cents,
-D.

Update: Welded in the Ford Racing X this morning - finally sounds proper! Love it

Borla website. I'm going to buy either the roush or Borla s type axleback (probably roush in a couple weeks) to replace the frpp touring. I've heard plenty systems that sound great but without headers. Whenever most people show off their exhaust at meets its parked revs or low speeds so even the raspy ones sound good. Even with 50ish 2015's last night I don't think very many had headers.
