FR500 Catback Interference with Billetflow Brace?

[Quick Strike]

I want to order a FR500 catback (M-5230-M58), but I am not sure if the X behind the mufflers will interfere with my Billetflow differential brace. Anyone have, or know of, a Cobra with the brace and a FR500 catback? I just want to be sure before I order.

Thanks :beer:

It should not hit. I know a guy that has the BF brace and the FR500 catback. :banana:

You might check with Doug but I've never heard of any catback interferring with the brace.

I checked with BF before posting. They said they had not heard of any issue, but could not think of a car with that set up off hand. They suggested I post-up here to find out for sure. And the wheel goes round. Thanks for the information so far. It is looking good.

Borla stingers can. Borla stingers can hit themselves if they arent aligned perfectly.

thats not the fault of the brace or the cat-back, though...

if your cat back hits the diff brace that means it hits the diff

The X in the FR500 goes right underneath the diff. I can't see how it would hit.

You're going to like that cat back. Noticable midrange improvement. But it's quiet and mine had a slight drone around 2200 rpm. Not bad by any means...but it was there. Funny...it didn't have the drone on my 01...which it was actually designed for.

I ordered it from Steve at the discount dealer on this site - [email protected] . Those guys has the best price I have found, and I have been looking a while. These catbacks are going out of stock from FRPP, and are only available while supplies last according to several places I checked. It may be time to buy if you have been sitting on the fence. I hope it is able to quiet my system down. Thanks for the help! ;-)

No, you shouldn't have any problems. I ran the FR500 on mine when I first put the brace on. The only reason I changed was because it was just too quiet around town. I actually had a more difficult time lining up my magnaflow catback correctly to keep it from hitting the weight under the pumpkin!

Is it quieter than Magnaflows?

 

[03 DSG Cobra]

Yes, it is quieter than the magnaflows. It was nice on the 2001's, but the lower compression on the 03/04 keeps it pretty quiet at idle/part throttle. It is nice at full throttle, but it definitely one of quietest exhausts I have ever heard (although, stock= "is my car running?" at idle).

I have always wanted to try an MRT catted H with the FR500. I loved the quality of the FR500, but it just didn't seem right for my 03.

Yep. Lot's quieter. I went to Magnaflows from the FR500. I'm not sure that was the wisest choice. The Maggies have a much more aggressive sound...but not obnoxious by any means. The FR500 has a dual mode muffler in it that opens up under WOT. So it's much quieter around town. The midrange is also noticably better with the FR500.

My Dad just put it on his car yesterday and he has the billetflow brace. No issues at all

Good Luck.

BTW, he is completely satisfied with the pipes, great system and almost stock idle sound, but when you step on it, it really opens up.

Okay thanks. I like the sound of the Magnaflow, however I think they amay be a little loud cruising at 2000 rpm around town - for my taste anyway.
