Yeah that is one option, another is ask people if there is another exhaust that is quieter.

All you have to do is find out what serves its function to you, through research.
Which is a better response then calling the guy a troll because he didn't search first. I mean really it's 4 pages of people freaking on the guy (with a handful of helpful people too) because one, they didn't read between the lines and assumed he only had an exhaust. And two because the exhaust he purchased is just too loud for him.

s8, not a8. Also, Lambos have **** for ground clearance, and I don't have a ton of faith in the AWD system, like I do Subarus. Plus I've driven a lambo around a track, and I really didn't see what all the fuss was about.

lol.

Thanks to the sane members. Whaddup to the guy who used to work at a 3 letter motorsport company.

Also I think I'll take my DP to an exhaust shop and have them weld in a cat and maybe look at sacraficing the invidia mid pipe and have a muffler/resonator welded in.

I was hoping for a concrete answer of 'If you install cat PN 5551234 instead of 5555678, you'll get 22.456432% more flow, and half the dB's', instead of the crapshoot of maybe it'll work, maybe it won't, like I've been doing so far after some 'research'

I'm just getting frustrated with throwing good money after bad with this car, and have been dissapointed by a few shops claiming to do good work.

That type of info doesn't exist. There are proven ways of quieting exhausts down. 1) install a cat, 2) install a resonator, 3) do both, 4) go back to stock.

There's no mystery to what you need to do; it's one of those four options.

The audi AWD system is much more advanced than the Subaru system. For gods sake Bentley has the same system! Watch the episode of top gear where tanner drives the new continental down and UP a ski mountain! Then you will have faith. And by saying S8, that's just proves my point more that your just trying to tell us you have money.

But as far as concrete answers to your question, just buy a stock exhaust, they still have good flow, or borla is a good system, my previous built ej20 had a borla before my invidia and the borla was much much quieter.

The fact that there are an infinite (probably finite but too many to account for reasonably) number of combinations of exhaust systems means that there cannot be a concrete answer unless each specific one has been tested out. This includes headers, uppipe, downpipe, midpipe, and mufflers. As a generalization, adding resonators restricts flow so expect slightly reduced performance. That is true also based on different tuner, different engines, different altitudes, basically there's a lot of combos that determine the power level of a car. As various have said you can take it to a custom exhaust shop and have this done.

Another alternative if you want a quieter ride inside is take it to a sound shop and sound proof the whole thing. Have them do the doors, the floor, the roof, the side, the trunk, essentially everything. Mind you, you will add 100+ lbs and it will affect performance slightly, but its another viable option I haven't seen anyone mention. So while overall noise isn't reduced, you will hear it much less on the inside.

On to the quality of shops, it might not be that they're doing a ****ty job. Maybe they did a good job but you weren't satisfied. A possibility there is that you weren't too sure about what you wanted in the first place, so you ask do this and they do, then you're like oh I thought this was going to be the way it works out, and from there a shop will try to accommodate you but may fail because sometimes there really is no options given what you initially asked of them...aka make a race engine quiet. If your only qualm is the noise level then maybe the shop didn't do such a bad job if you think about it.

But yea check out soundproofing, I've read that second skin is really good if you add two layers: the basic one then on top luxury liner.

Edit: PN5551234 is a great option!! Just make sure you overnight from Japan. /sarcasm

Wow... this thread...

Another example of no research before buying and total lack of knowledge on the sound dynamics behind exhaust....

Putting cats in? lol, that has no effect on sound level... troll

I'll be more than happy to trade my stock exhaust for yours.
