Rate this exhaust setup

[silv00]

I really need some opinions before I drop $800+ on this setup. I'm tired of researching...I want my exhaust!!!!!

I've got a stock 2000 GT that's driven about 200 miles a week. I'm looking at a catted Prochamber with an SLP Loudmouth II catback.

How will this setup rate for the following (1-10, 10 being the best vs. other setups):

Gas Mileage:
Horsepower:
Noise level:

Thanks gang. I can't tell you how cool it is to get this kind of help.

gas mileage: shouldn't really change
horsepower: 10-20HP
loudness: at WOT it'll scream other than that it should be louder than stock since you are getting a catted mid pipe

edit: but not as loud as if you got the O/R pipe

gas mileage shouldn't change, hp increase will be like 03ghoststang mentioned because it really depends on what other mods your car has. anyways, your setup looks good, an o/r midpipe will defnitely increase the volume and hp gains.

hp: ~5ish. if you decided to get an o/r midpipe, then ~8-10.
noise: pretty loud.
gas: not even enough to make a difference.

Then get some longtube headers if you dont have to worry about emissions ($%#^& EPA) amnit:

yeah HP wont be much 5-12, depends on what you get. The new h-pipe will make it sound better. but an o/r will be crazy. MPG wont change i dont think. But i cnat really tell you what a SLP will sound like since i got a mac pro chamber and mac cat back. good luck with your purchase...

ive got the LMII's and they sound great, but they are paired with an o/r X-pipe. i have some vids if you wanna see them.

Speaking of SLP did they go out of business or what the guy telling me that an idiot?

im sure your mileage will drop significantly, especially in the city, since youll be wanting to hear the exhaust bounce of of buildings and such. i know mine dropped cause im constantly taching 4k before shifting and going 3/4 throttle cause it sounds so beautiful. but then again thats just me, if you have any shred of willpower, maybe you can hold back on letting it roar.

i havent heard anything like that. i'd be surprised if they did, because i just got an e-mail from them offering me 10% off any order for the holidays. on top of that, with the introduction of their Loudmouth exhaust systems into the mustang marker, they've been selling like hot-cakes.

i doubt it since when they started chevy was there bread and butter with the camaro and vette. When the camaro was no longer in production they went into mustangs, but dont see why since they still make parts for the vettes and GTO's
