I don't know where to begin. I am looking at SLP loudmouth I with slash tips, K&N Cold air and tuning the computer. I figured with those upgrades, I will get a little more excitment than the stock LS1. Any other thoughts to these and any other quick bolt on upgrades to gain the most HP?

stock LS1 not exciting enough for you? lol

do the free **** first.

Do your full exhaust and intake (lid)

and tell us if its a m6 or a4

If it is an auto, save you money on the exhaust and get a 3000+ stall TC. I will be a night and day diffrence in your driving experiance.

If you have a M6, do the exhasut and a lid. Save the tuning until you start getting some biggers mods like heads and cams etc..

Don't Go with Slp Loudmouth, Instead go with GMMG Chambered I wish I had of. It's expensive but it's worth the $700.

I would suggest doing the Free ram air mod with a K&N filter, a lid, and a catback. I would go with SLP for the lid, but I would stay away from the SLP loudmouth, personally, I've heard them on other fbody's and it reminds me of cheap glasspacks. A lot of people don't like the Flowmaster Cat back but I have a it on my 99z and I love it! Took longer to get the stock exhaust off that to put the new on. It has a nice low tone at idle and is not overbearing on the highway. Under $350 through Summit Racing. Also, I'd knock out your MAF screen and do a throttle body coolant bypass too.

305 hp is not enogh, One day I would like to see 500hp! Sorry but 80mph is like doing 35mph to me.

It is a A4, What free **** are you talking about?


I am looking for an exhast that is both loud and most HP gains.

i have slp lm on mine and i get compliments all the time on the way it sounds. If you like it loud then slp lm is the way to go.

Free mods are definatly the best to do first.... you notice a lot of gain from FRA, ported/descreened MAF(may throw a code), tb bypass, !CAGS, ect....

its all fun stuff that you should do on your own...
