Exhaust

**99Ztwenty8** · 11-13-2006, 09:00 AM

I just recently bought my z and it is just about bone stock...I want to get an exhaust that will sound bad ass and give me a modest gain in the hp department, however am not made of money, any ideas..
Thanks guys

some good chioces are :

SLP Loudmouth $400 - very loud

Magnaflow $450 - stainless - low rumble until full throttle

Borla $800 stainless - adjustable

There are many other choices as well. Any one will gain you hp and a nice sound. Just stay away from flowmaster.

now now now, a flowmaster will give you great sound i have a 40 series flowmaster and i love its sound, deep rumble and lout wot sound but quiet enough not to attract too much attention as the SLP loudmouth would

I too like the sound of a flowmaster but have saw losses on a dynojet and mustang dyno with a flowmaster, even up to a 25 horsepower difference on a full bolt on heads,cam car. I personally prefer the magnaflow, barely a loss on the dyno like less then 5 horsepower and for the money its a decent piece but if your talking real exhaust I use a h-pipe setup with eldebrock true duals dumped before the axle but again i would only reccomend this to some-one with a camshaft.

the only stuff that will benefit you is the Lid, exhaust, and rocker arms. Thats probably a solid 25hp.

Everything else combined will give you maybe 5hp so not worth the $$.

like they said , you really dont need all that, but for the price its a good deal, the exhaust, CAI and programmer alone is that much.

I just had the SLP LM on my last Z it was pretty good. I liked the rumble it gave me. Then I totalled that one and got the one i have now and it came with some sort of flowmaster catback. And to be honest, it sounded better than the LM all the way around. Loud at WOT and a good rumble at idle. But since I installed my LT's, the car is quieter than what it used to be, so now, I am getting another LM for this car. But some people don't like LT's and LM combination, I think its going to sound RAW.

**Sassy Cassie** · 11-14-2006, 07:41 AM

Corsa has the best sound, imo.

**FasstChevys** · 11-14-2006, 07:59 AM

I have heard bad things about Diablo tuners for LS1's

**SSNAKEATER23** · 11-14-2006, 09:30 AM

GMMG all the way. i have a magnaflow cat back, but i'm prob going to upgrade asap. Sound is great, deep and loud.

**SSNAKEATER23** · 11-14-2006, 09:32 AM

Whats so bad about the Diablo tuners?

there is nothing bad at all, unless you dont know how to use them. i have one and it's great, you can monitor shift points, fan temp...too much to list but a very good investment by far.

**craz28** · 11-14-2006, 01:51 PM

Honestly what I would have done now instead of a catback is just electronic cutouts, so that when u get headers u can still use the stock catback to be quiet and when u want to be loud just open up the cutouts.

**SSwt00SS** · 11-14-2006, 02:04 PM

sorry I'm biased, but I love the sound of my car, LM all the way...lol

I noticed that yoru putting down 326rwhp and 330rwtq with the LM exhaust.

what would you estimate a Magnaflow cat-back to put down on my SS with my mods in sig.?

**SSwt00SS** · 11-14-2006, 03:18 PM

I would estimate right about the same. +/- 5hp/tq respectively...

I'm not talking shift points, fan temp, etc, etc........I've heard that the claimed gains in horsepower aren't what they say they are. Take it for what it's worth.

What about using the Diablo after a Hooker LTH and ORY installation? I just did that today and now need a tune.
I think my exhaust is now more raspy when I am on it, and almost as quiet when just cruising. I have a Raven performance muffler from Midas, it had a deep tone before my LT/ORY. I might be looking for a different muffler now. I do like the looks of my stock tailpipes, so I will just maybe be looking for another muffler.
