Borla makes two cat-backs for the R56, the "Touring" with a single muffler and the "Aggressive" with two smaller mufflers. Otherwise the systems are the same, with dual 4" tips. We installed the Touring on our shop car.

I love the look, and it sounds nice. Very discreet, not at all loud at idle or steady cruise. A little more bass sound. And on acceleration, there's a more raspy tone, but nothing that's in any way obnoxious. I don't think I'm going to be worried about attention from the law.

And, we took a little video!



Edit: Here's the twin-muffler "S-Type" system. Same except for there are two smaller mufflers in the rear, instead of one larger one. More aggressive sound.

Nice!!! How does it compare to the ALTA system you had on before? At least I thought you had the ALTA system...

 

So which one did you end up installing? Sounds really nice by the way.

How was the install? Where is the stock exhaust cut in order to install this? Would it fit with Alta's downpipe?

Nope.

 

The "Touring" system.

Really easy. Cutting the pipe is probably the hardest part. We used a Sawzall, which made short work of it.

Between the stock rear cat and the front muffler.

I assume not, since it's designed to slip-fit over the stock pipe, which is smaller than the aftermarket downpipe.

Very nice. I assume there is little, if any, performance gain (??). The sound is very mature and appropriate for the car.

 

I'd guess not, but we'll find out for sure some time soon when we put the car back on the dyno.

BTW, what wheels do you have? I really like the look with anthracite + polished lip.

 

Thanks. They're Rota RB's. Read all about them here.

Dan,

great looking R56... one of the best I have seen

 

it sounds GREAT!

but i do not liek the idea that to mount it, there needs to be cutting.

 

that video makes whoever is filming look really tall

 

That is such a hot R56. Great job with it! Borla sounds good...would love to hear the louder version though, the tips look great as well .

 

There's really no way around that. Almost the entire MCS exhaust, INCLUDING the second catalytic converter, is one solid welded piece. That means to have a street-legal cat-back system, you're going to have to cut the factory system.

not to mention it's easy to reweld the stock system should one ever need to put it back on. heck, I just cut a system I sold in half and shipped it to Australia - the new owner had it tacked back together and installed. :tu:

 

Good luck finding an aftermarket exhaust the doesn't require cutting out the factory system.

Car sounds great BTW, and those tips are hawt!!!

 

the more I look at the Borla, the more I'm loving the 4" tips

 

mmmhm after i get my goliath back this might be a late christmas present!!!! *goliath found a deer one day headed to see some friends *

 

just got back from Mach V....I heard this in person. For you former R53 people, this system is to the R56 what the Milltek is to the R53.....not stock, but not a fart can either....just right.

 

I added a second video of the (not much) more aggressive two-muffler system.

did I hear the quiet one today?

 

Wow, I never listed to the clip before but that sounds amazing.

 

Is this the same for those downpipes from Alta and Milltek?

 

Yes.

I think that's the first video/clip of the Borla S system, it's really hard to tell the difference, how would you rate/compare them side by side ?

I love the Alta downpipe, but their muffler's just too quiet, it'd be great if there was a way to combine the two. I want to be able to remove & keep my stock exhaust un-modified (un-chopped) in case I ever need to take the car in for warranty purposes.
