Are you telling me that by changing out the stock exhaust for any of the above you only gain a maximum of just under 14 hp. Seems pretty weak considering most exhaust systems start at $1,000. Somehow I don't trust that chart. And how does that relate to cost, and other considerations?

Ah. So I assume there's a big difference in hp gains simply by replacing the downpipe in addition to the cat-back? How much is normal? And again, who's turbo-back system meets the above requirements? Thanks again

the only real reason i see to get a turboback is to have matching parts and to say..."i have a turboback", if i had a wrx i would get a downpipe and catback just to save money, as for the hp gains im not sure, do a search im sure youll find something

But doesn't a downpipe + catback = turboback?

Down pipe and cat back= turbo back regardless if the manufacturer is the same.

Let's assume I'm talking about a turbo-back system, or at least a good downpipe/cat-back combo

Not all downpipe + cat backs = turbo backs.

Many downpipes end before the 3rd cat (midpipe) and so you'd have a downpipe, midpipe, and cat back.

TurboXS's website states that there TB exhaust is good for 26.5 whp. You can buy them from Garett at WorldOnePerformance.com - he sells them for like $1059 shipped. Nice increase in power and its suppose to sound sweet. Not too loud at idle and a nice boxer burble when on the gas!

sharky, yea those are whp gains, but they are measured by finding the biggest change on the graph and recording that difference and they are also done by a car magazine. Dont give those numbers much weight...unless you really like disappointments.

sdseagles, when ppl talk about exhausts TB stands for turbo-back. If youre looking for best bang for the buck, scoobysport should be near the last on your list. Its not cheap and doesnt flow as well as 3inch systems. If you want something in 2.5inch, go with buschur. $250 downpipe ($400 with cat) and $375 catback makes for a $625 TB, about half the price of scoobysport and higher quality.

Theres tons of options out there, you just gotta decide if you want to go catless or not. Then pick a catback that you like and match it up to the downpipe of your choice. Turboxs sells a midpipe that allows for their downpipe to be bolted up to any aftermarket catback. The perrin downpipe is the just about the highest quality piece on the market and vishnu even sells their own catback exhaust now (eventho I wouldnt call it a good deal at $795 ).

Default TurboXS is NOT magazine numbers!!

I have to disagree with you mlambert, TurboXS has dyno plots on their website showing the difference between the stock set-up and their own TB exhaust. The area under the curve with TurboXS is nice. It is even more linear in the 4500 rpm to 5500 rpm range than the stock set-up. This equates to smoother power.

On top of that...TurboXS is NOT taking the biggest change in the graph - they're going with peak horsepower. Plus, the TurboXS car hits its peak horsepower approximately 242 rpm quicker than stock.

Check out Scoobysports (hayward and Scotts) from Rally Performance that complete system gives out 25 BHP.

I wasnt referring to the turboxs claims at all.

What I was talking about is the HP and TQ gain list pasted by Dr Moreau. Thats from sport compact car or some other import magazine and they listed those gain numbers as the biggest gain anywhere on the chart compaired to stock. I dont take hp gain claims from import car magazines very serious. I take posted dyno plots from respectable companies like turboxs serious.

mlambert, what if I wanted a high flow exhaust with only one cat, would you still recommend the same? Is there a system with only one high flow cat that still opens up the exhaust, increases power and torque, but is still good quality and reasonably priced? Thanks again for everyone's input

Ya'll have all missed the piont-----


The best free flowing exhaust for the money comes from mexican food Now, mexican food is catless, so you could see fireballs shoot out of the rear end.. But its good for at least 30-40 hp on the butt dyno...

Link didnt work..

Had to delete the wrx suffix to get to the site, then I clicked on "wrx stuff" on bottom left column. Found all sorts of cool stuff.

I seem to be getting a lot of recommendations for TXS. Do they have a turbo back with a single high flow cat? What is the exhaust note like at idle and WOT? Thanks

Is the 2nd cat integral with the dp? DOes anyone sell this hypothetical short dp?

If that was the case I would leave the stock 2nd cat and get a custom pipe made after that with a cheaper universal muffler, eliminating the useless 3rd cat.
