i listened on ls1sounds, not a big fan of that site though, all the cars have cams it seems like, and i like opinions as well

i am looking for a catted setup

headers back, full exhuast system

i am also not worried about performance here since the car is stock and will remain that way for a year or so at least

in ya'lls opinions, which setup(brand names) would give me the best sound outside while, being "quiet" on the inside, i make frequent 3 hour drives

also, would setup would just give me the loudest sound, not considering inside noise

how much worse inside would the loudest systems be inside the car than the "quiet" systems

thanks for the help

oyea, i have to be able to easily get inspection stickers in texas

 

Loudmouth with Lt's eat your heart out...or you can always do the dual cutouts

 

If you're looking for something simple, just go with something you have heard of and you wont be dis-appointed. Something along the lines of Borla and Corsa if you have bank, or Flowmaster and Mangaflow if you are tight on money. TSP also has a decent exhaust, light and good but a little louder on the inside.

 

LT headers and magnaflow is suppost to be one of the best setups out their. But I like the LT and SLP loudmouth b/c its more raw. All a matter on opinion. Try and find people in your area so you can hear it in person

 

jwhert, for a great exhaust system, I suggfest a true dual system. In order to keep it quiet and street legal in all the states, here is what I suggest. Run both pipes (2 1/2 inch) down the passangers side close to the body exactly where the factory exhaust runs, then go over the axle with both pipes. Then through straight through, noise cancelling mufflers (one placed on each side of the rear tub) then out the rear from beneath the bumpoer in the stock location. I know that everyone says go with a "X" pipe up close to the engine, but I say NO, use a "H" pipe with the holes in the pipes (into the "H" pipe) no larger than a dime. All that you want to do is equalize the pressure between the two pipes. Using the stock manifolds (which are quiet well designed and flow quiet well) and leaving the cats. in their stock location and the use of the straight through, noise cancelling mufflers you get good performance, a great sound without the loadness and you will pick up a number of horses. That is what I did and in before and after dyno testing I picked up about 15 horses over SLP's loadmouth and that stupid "Y" pipe system that came on my car. By running the pipes exactly where the factory pipe ran, you will have far better ground clearance then you had with the stupid "Y" pipe system. With a system like the one that I suggeted, you will get a great sound without the loadness, Pick a few extra horses, improve gas milage, look stock, be street legal everywhere, have no roar on drone inside the car (quiet as when new and stock), have a true dual exhaust system and with more ground clearance than with the factory's stupid "Y" pipe system. What more could one ask for in an exhaust system?

 

do you have any pics?

i havent actually seen under my car, ive looked, but i havent actually had it on a lift so i could see good

what would a setup like that cost

whatever, before his site, we had nothing

Flowmaster

Hooker, SLP Dual/Dual, Magnaflow

3" True duals X or H, dumped. Catback option, Loudmouth

how much worse inside would the loudest systems be inside the car than the "quiet" systems
Makes your torso resonate (see TD's dumped).

You keep saying this in all your posts, but it isn't true. TD's are not legal in California. I hate to keep correcting you, but it's the truth.

 

I'd like to see some pics too, if you have any. Many people seem to proclaim better clearance with an H pipe over the X, but I rarely see pictures. For clearance alone, I'm considering going with LT and the factory exhaust setup (aftermarket y and cat back, of course). It'd be nice to have convincing photos of a True Dual setup, esp. an H pipe, with just as good of ground clearance.

 

Technicaly there are no "legal setups" but the stock setup.
It is illegal to remove cats
It is illegal to put Midlenght, or Long tube headers, and couple them with custom catted Y-pipe (this moves cats away from the exhaust ports, making temps lower, hence decreasing cats' performance)

It's good that a lot of states have OBDII testing, and with proper tuning you'll pass "emissions" even if you have straight pipes, but the law has not changed - it's STILL ILLEGAL....

 

Redneck Z, You say that TD's are not legal in California and that you hate to keep correcting me, but it's the truth you say. Well, are you telling me that the Mustang can"t be sold in California? It has true duals you know. Besides, I know for sure that there are a bunch of Camaros in California that have true duals. I'll repeat, If you leave the stock manifolds and the stock catalytic convertors on and in their proper place, True duals are street legal everywhere.

 

True duals are NOT LEGAL everywhere. You just mentioned the difference right there. Mustangs come stock with TD's so they are legal. LS1's don't, and that is why they aren't legal. In CA you must maintain the stock exhaust configuration. You don't live in CA anyway, so what makes you think you're right? What does a buch of camaros running TD's in CA have to do with anything? That doesn't make it legal. Tons of LS1's in CA also run LT's and big cams, does that make it legal? Before go out and start spreading this myth, why don't you call a smog ref in CA, and find out yourself.

 

I'll tell you what... I read all the posts here and other sites before I bought my set up. I went with Borla adjustable exhaust and cat. Nice sound outside and quite inside (unless you jump on it). The Borla adjustable has three plates to adjust the sound, 1/4 open, 1/2 open, and 3/4 open. And I guess you could remove the plate altogether and have a full open. I run mine at 3/4 open and it is fine.

 

thanks for teh replies, keep em coming

and i guess i should mention that i dont care if the exhaust is legal, but i care if i can get an inspection sticker in tx, i dont know what method of testing they use here

 

Unless/until they look under there with their mirrors. This is less likely to happen with a dead quiet/smooth idling car with everything tucked up as much as possible. Stock exhaust tips and no skinnies/DRs can't hurt either.
