View Full Version : Christmas Present

12-06-2005, 12:58 PM
So the parents are asking what i want for christmas, so im telling them i want exhaust...custom. heres what ive got lined up. tell me please if you see any problems with anything listed. ive already got an ecode testpipe, then im thinking techtonics tuning 2.5" downpipe, get the shop to custom mandrel bend 2.5" piping back to a magnaflow 14816. im a little confused when it comes to a resonator though, i looked on ebay at cheapo 2.5'' inlet/outlet resonators. does anyone with custom exhaust have any experience with those? please guys give me opinions on what my potential set up is. and custom guys help me out with the resonator please!

skip the resonator and go loud!!

12-06-2005, 03:30 PM
nahh....im not all about a super loud exhaust. i like a low growl, and great sound at WOT. would you custom guys mind posting sound clips for me? also what about the resonator?

12-06-2005, 03:34 PM
Just my opinion but wouldnt 2.75 be better?

Thats my plan with a chipped K03 - 2.75'' should be fine.

The Borla is only 2.5" which is fine especially for a K03. The Borla doesn't use a resonator does it? It's just a cat-back with one muffler and nothing else?

I think you need to ask for a silver hood so i can buy your beat up CF hood :)

i guess it would have been smart to post my mods in my original post. i have a K04 with GIAC. just running the testpipe now with stock exhaust. i need exhaust for christmas. im planning on pc16 in the near future, so i dont want anything too small. im worried though if i went 2.75, i would have a 2.5' dp, and then the magnaflow would have an inlet of 2.25''. is that too crazy with all the different size inlet/outlets?

actually the borla is ony 2.25, and they claim a 15hp increase.

lots of people run 2.5 (or even the borla, 2.25) with k04s. works just fine.

as for the "cheapo" resonators off of eBay, i'd skip and go with a magnaflow one. i have an 18" resonator, and the whole system is still kinda loud, especially when i punch it. but the sound is high quality stuff.

a good resonator isn't all that much more $$$, especially when you consider the long-run. don't skimp on that, just my 2 cents.

12-06-2005, 04:52 PM
thanks joey. what resonator do you have? is a resonator just a mid-muffler?

12-06-2005, 04:54 PM
love my Milltek and its 2.75"
ran my milltek when i was chipped with just k03 too...worked great then. works great with k04 and will work great when you go BT [;)]
the need for more power is inevitable.

Hey, I have a 1998.5 A4 1.8tq 5-speed with the 2.5" Magnaflow cat back exhaust system with a down pipe. It's honestly one of the best sounding exhausts I've heard on an A4. I paid $575 for the entire system brand new, installed. Where as my friend paid nearly $1,000 for a Milltek cat back system + installation on his A4 2.8 and it doesn't even sound close to as deep and throaty as mine. PLUS Milltek has shitty connections and even after taking his car into Matrix Integrated THREE times, once for an entire day, the he STILL has small exhaust leaks and when the system heats up, it hits his chasis making a very annoying sound. I'm in no way ripping on Matrix Inetegrated, they're one of the best in the business! The exhaust was just poorly engineered. The Magnaflow exhaust is definitely ALOT of bang for your buck! And It's not too loud and never gets raspy or anything like some of the exhausts you hear out there... It's perfect! I get lots of compliments on it ranging from little old ladies to Audi enthusiasts such as ourselves. Magnaflow is the way to go if you're not looking to spend a TON, you won't be dissapointed! [up]

IM me on AOL Instant Messenger @ CaSp3r9 and I'll be happy to send you an audio/video clip of my exhaust if you'd like! [a4]

anyone see any problems going 2.5'' dp, 2.75'' piping. resonator. 2.25'' magnaflow 14816? i might just go 2.5 all the way. what would be better?

edit: where can i find a good 2.5'' resonator for cheap?! im not sure what the hell a resonator is so please help me!!

3" testpipe to a 2.5 downpipe with straight pipe mandrel bent one piece 2.5 piping to a 2.5 magnaflow muffler...sounds amazing...no resonators or anything

12-07-2005, 06:28 AM
so about resonators. i think im sure what they are now. i have three of them in mind, all magnaflow. which one do you guys think would be best for my application? K04. testpipe. GIAC.

part number 10426

part number 10416

part number 10436

im leading towards the 10416. anyone have opinions?

12-07-2005, 01:40 PM
what about no resonator? im not 100 percent sure i want a resonator...would you custom guys with/without resonators post sound clips...PLEASE??? also please post your setup! thanks!!!

I would get the 10426 center silencer as its not that big and has a 2.5" inlet outlet.

Just get a 2.5" system as well it will work fine.

Here is a Vid of my car with a straight through system.


I run it most of the time now though with a bolt in silencer place in the backbox and will probably get a center silencer fitted next year.

I think it sounds great but is too boomy in the car at times.

Here is another one of me pulling away with the camera closer.


They take a while to load.

12-09-2005, 08:38 PM
Heres what mine sounds like with not much interior, with interior it would be ALOT quiter. But it will give ya a idea...

2.5" is generally good up to 400bhp. I run 2.5 turbo back. magnaflow resonators dont' do anything but remove some of the raspyness of a straight exhaust. I have a 4" OD resonator and it's still bassy as fvck. Too loud in my opinion.

12-11-2005, 06:53 AM
DAMN AB18...your car looks fast as balls from the video. exhaust sounds awesome. thanks for all the input guys.

12-17-2005, 11:31 AM
so heres the deal guys...i just talked to my parents and they said they want to get me exhaust for christmas...for sure. now all i have to do is piece to gether the parts, and then they will order them and i will take the parts to midas and have them install them as well as get me custom mandrel bent piping. heres what ive got in line..

so far i have an ecode testpipe, and from there im going with a techtonics tuning dp.

custom mandrel bent piping to center resonator. magnaflow 10426

custom mandrel bent piping to rear muffler magnaflow 14816. i have an eribuni rear bumper so im not worried about the tips being too big.

i know good things of everything magnaflow, ive just never heard any good things about the TT DP. i mean i know its not a piece of crap, i just would like some reviews on it. people please if you have a TT DP or any other product from them, please chime in and tell me good things!!!! i need to know about the DP ASAP, so my rents can order the parts. thank you!!!

come on guys, no one?
