Re: low budget bolt ons? If you are not going to do headers, a y-pipe might be good to unleash the hp killed by the stock pancake y-pipe. An ASP crank pulley might be a good mod. You might also want to consider a cold air induction kit (CAI), a high performance lid, or smooth bellows. You could add all of the above for less than $800.

Re: low budget bolt ons? If you wanted to go with a cutout, then I would recommend the electronic one, simply because you dont have to unbolt it everytime you want to open it. All it takes is a switch of a button..and bam! its open. Anyhow..if you wanted to go with a catback...I would recommend the Loudmouth. Some say they love it...and some say they hate it, but I have had a stock exhaust with a 2 chamber muffler and the exhuast mod, the Borla, and now the Loudmouth and I would have to say that the Loudmouth is my favorite. Its the highest flowing catback on the market. Instead of using a muffler over the axle, it uses a resonator in the i-pipe. From there you can go with a ram air kit, pulley, lid, ported/polished throttle body (I recommend the one from Bauer), maf sensor, ported ends, plugs, wires, filter, and maybe some of the free mods. Hope that helps. I would buy some long tubes if you had the money to work with, my favorite mod. <img border="0" title="" alt="[Big Grin]" src="gr_grin.gif" />

Re: low budget bolt ons? if you have an automatic you wont want to put on maf ends or any aftermarket maf, unless you are getting some form of tuning done for it.
start with a lid and catback. lids and pretty generic wether you want a clear, black, or carbon fiber will be the decision to make vs which brand.
these will run anywhere between 150 for lid and K&N to 200.
as for a catback you have many options. you could just do a cut-out which is the least expensive but also gives the most drone inide the car. from the high end corsa, borla and B&B to the dynomouth, flowmaster, loudmouth its all personal preference.
if it were me personally now knowing what i know and i drove a camaro, i would get some longtube headers on there and slap on a dr. gas x pipe and just dump it <img border="0" alt="[evil]" title="" src="graemlins/gr_devil.gif" /> <img border="0" title="" alt="[Big Grin]" src="gr_grin.gif" />

Re: low budget bolt ons? Won't a cat-back bust your budget? The dual/dual is nice but will exceed your budget. A catback will only net you about 10hp. Most people only change for sound. A cut out might be more cost efficient. You may have to do a little research.

Re: low budget bolt ons? yeah i cat back would pretty much be my budget if i got a corsa or something.....but if it is that much better than a cut out then id get it and just wait till i could afford an air box lid and other thinks like that

Re: low budget bolt ons? "a y-pipe might be good to unleash the hp killed by the stock pancake y-pipe."
You'll pick up exactly zero HP by going to a round y-pipe of equal diameter. That flat spot does not impede flow. GM knew what they were doing on that one. It's there for ground clearance. NASCAR uses the same type of pipe for the same reason.

They took an LS1 Y-pipe and started crushing it in a vice at the crossover and found they had to get to less than half the original diameter to get a measureable backpressure delta. The reason is it's a localized reduction in diameter meaning while you are compressing at the front of the reduced section you are expanding at the back of it, it ends up being a wash in the end.

Re: low budget bolt ons? Nope, the y is probably not worth it. On a budget I would go with a:
1. Lid
2. Cutout
3. Converter
4. MAC mid-length headers
The converter would be some $$ but a must for an automatic. Check with dealership to see what they say about the converter and the Headers for warrenty.

Re: low budget bolt ons? Any converter will void your warranty. i went with a Vig, since they state that they will not void the man. warranty and when I had some work done I ended up paying out the ***.

A lid is a great first mod.

Once you start getting into some more serious power (heads/cam/headers) you'll see some descent gains by using a larger Y-pipe. I'm running a 3" Y-pipe but I'm using 1 3/4" headers and have plans for heads/cam this year. When you get on up into large CI engines a bigger Y-pipe is crucial.
But, for running stock exhaust manifolds and internally stock, you are perfectly fine with the stock Y-pipe.

Re: low budget bolt ons? The Dynomouth exhaust is great sounding and very affordable...
Mine was $140 WITH professional installation.
If you are interested, all the info, pics, and sound clips are on page 2 of my website.
