I recently purchased a 00Z A4 with 3.23's. My question is this, what mods would be necessary to reach consistent 12's, with little difference in daily driving. I am not opposed to a cam change. I have actually been considering doing a cam change without heads. I don't want a crazy setup. Definitely on a budget. Obviously, I will start with an airlid. I do have to pass an emissions check annually, where they are supposed to look for cats. Would this be possible for around $1000. I have read that many people suggest full length headers. How loud are they? Interstate driving is something I do, if you know what I mean! About the free mods, are they really worth it? I read an article in GM High Tech Perf. where they did all free mods on a TA A4 with 3.23's and only gained a 1/10th. To me this is not worth it. I guess if I run 13.00, then I might consider it!!! Thanks for your help and expertise!

I'm thinking it MAY be possible. You're probably going to have to hit the perfect combination of parts and have one hell of a tune on that budget...

all work is going to need to be done by you and maybe even learn how to tune with trial and error to save money.

But my slightly educated guess is yea, I think it can be pulled off for close to a grand.

1000 is what I'm thinking for now! More $$ to come down the road. I have seem some sigs on here that show people running high 12's with few mods.

yea the LS1 responds very well to bolt-ons. You're going to want the lid first off, and I would venture to say it can't be done without some form of exhaust work. Then a stall and maybe D.R.s could do it. Then possibly tuning if you aren't there yet.

Start researching about torque converters. That would be money well spent on your A4. Also look into a set of tires for traction. Do exhaust and your airlid and you should be high 12s.

yea Id do a low stall since you wanna keep it for DD, and exhaust and a lid should get you their with good driving

There's so much information on this site...take some time and look around and figure out a plan, price stuff out. If I was in your shoes I would invest in a pair of good drag radials before anything else...see what it does, and go from there. You're A4, so breaking into the 12's can be had relatively easily. As for the free mods, I never bothered, I personally don't think they're even worth doing....but then again they are free, so that's up to you. Hope that helps you out!! Good luck with the 12's man!

Unfortunately, the previous owner was kind enough to think that the sound of the evil muffler(Flowmaster), was great and so he put one on the car. it's not a catback, just a welded in muffler with factory tips. How bad is it? Please be easy on me, as I didn't buy the muffler myself.

get yourself a lid, longtube headers, a catback and a ported throttle body. you should be able to hit 12's for sure. now get yourself an LS6 intake and a tune and you'll be consistently in the mid-high 12's on an A4 w/3.23's. these mods will give you 60+rwhp to the wheels for sure.

see what it runs as it sits, it may run 13.2's or 13.7's go get a base line

Your flowmaster is worthless to you...other than worth a few bucks towards a cat-back.

You will need headers of some sort and a catback for your goal.

Look at Mac mids since you need to be emissions legal and have cats. They are very affordable and sometimes you can find them used on the board here.

Would it be worth getting a cutout, and leaving the muffler alone? This would obviously be cheaper than a catback.

Yes that would be fine. I have a E cutout myself.

The cutout's not actually very loud, it's raspy but for the cash it's decent.

get a stall and a 125 or 150shot of N20 you'll have 11's easy on a DD

i had a 98 z-28 with a 3chamber flowmaster welded in/stock pipe,off road y-pipe,L.C.A,free mods,slp air lid,k&n filter and ran 13.19@106.i would try a lid,slp mass air sensor,and a tuning with the muffler you have and get rid of the cats if you can they made the big difference. you sould hit high 12s no problem.

mac mids are completely worthless. they aren't CARB legal and they relocate the cats so if you are in california, mac mids will fail inspection. as for the sniffer, mac mids won't cause anymore emissions than longtubes as long as you're using cats on both. get longtubes or keep stock manifolds.

A stock M6 with DR's w/ a good driver will hit high 12's all day long FWIW

Lid/catback/stall will get u in 12's and be very driveable on the street & all that can be attained with $1000 (not including labor)IMO
