Best exhaust system

[VeNoMS4]

I'm currently looking for a new exhaust system for my S4. I prefer the non-resonated sound.

Just wanted to ask the community what are the best "bang for your buck" cat back systems out there?

thanks

IMO AWE Touring.

That said, I can't see buying any of them for the prices they are asking given there's near zero gain except sound.

AWE Touring (cut out stock resonators on DPs replaced with straight pipes) LOVE IT!!!

[DannyDeez]

OP I know you said you prefer the non res sound, and AWE touring is resonated, but it really sounds amazing.

[stigster]

Borla. Best note to my ears. However, best bang for your buck.....prolly this CTS on sale:

Can't go wrong with AWE. Probably most popular option. Other solid ones are Borla and Milltek. Really comes down to personal preference honestly

[VeNoMS4]

Thank you all for your replies. I've heard mixed reviews on the CTS. I do like the AWE and Borla is a new contender for sure!

I thought the touring was non res and the track was was reso'd

The best system IMO is the Milltek ValveSonic.
The best value for money system isn't the ValveSonic :)

[MrFunk]

Are you sure you prefer non resonated? Louder? Drone?

If you want to get at least 20 differing opinions on something, just ask what the best is.

[ntsantos]

You can save huge $$ if you buy the mufflers (magnaflow, borla, etc.) and have a good shop install them with 2.5" piping.

I did a full magnaflow system, mufflers and resonated x pipe, and tips for less than 600.

Milltek, non res.. make that V6 sound like a throaty V8

[hurricanes28]

Does any one know if it is possible to customize a 3.0 Non-Resonated down pipe for a q5 2.0.

Yes! I've heard those. But it's pretty expensive system. But I suppose you do get what you pay for

Of course. I saw some videos on the awe system which has a slight done but I can handle it. Just wanted the community's opinion

I did a side-by-side before buying mine. The Milltek is more of a higher pitch, "European," sound. AWE is a throatier, more "American" note. Both sound good, and either is good for 5-8 hp, so it really boils down to personal preference. Haven't listened to Borla on the S4, but literally every other aftermarket exhaust system I've ever owned has been a Borla...love that company.

[S4Drew]

Total n00b question, but will someone please tell me if I am correct in thinking resonated = has resonators = muffled a bit more? Or explain further for me if I am wrong?

I've been debating about exhaust also, but to me this is one upgrade I don't see myself doing. Our cars are relatively quiet, but I think they have a nice deep growl. From what I've read on exhaust systems there is no real HP increase, so it's all for your own pleasure or that of those around you, but it also draws attention to you. On a V6, even the throaty exhaust systems still sound like upscale rice to me (IMHO), but that could also be because I'm hearing it on crappy computer speakers and not in person. Not hating at all, but for the price, I could think of better upgrades.

I would say it is exactly 100% the opposite, AWE has a more "eagle's scream of death" while Milltek is more like "Angry Cthulu awakening". They both sound great but Milltek is most definitely more "throaty" in my opinion.

[hurricanes28]

So you all agree on a Milltek system. How about a manga flow

You are correct on both things.

I just got AWE Touring with Non Res downpipes installed and OMG...

It sounds amazing

[Frinkferta]

A used system from a forum mate is the best bang for the buck.

AWE Touring & end thread

Not only for the aggressive tone, but also for their world-class customer service

That sounds insane for a v6 to sound like a v8! are the exhaust manifold different lengths?

The CTS on my B8 has very little drone if hardly at all. I think I even want it louder.

[VeNoMS4]

Ok thank you all for the suggestions.. i have lots of tips to go off of. END THREAD

It's the last of the v8 ... They switched to v6 last year that one sounds like shit

I'm surprised nobody ever mentions a Corsa exhaust. I still haven't really heard one on an S4 yet, but I always used them for my trucks. Nice deep sound on wide open throttle and no drone inside the cabin. There's only like 2 YouTube videos out there, kind of disappointing.
