      Which one does everybody have/recommend for the corrado?

      I was told that maybe a test pipe (cat delete) would sound good, but I am open to suggestions....as my corrado has a hollowed out cat, and it sounds VERY much like an exhaust leak right underneath the cabin. I checked the exhaust though, no leaks, just sounds ****ty.
      Let me know, i woul like my car to sound better

      Sure, I have seen some of them, but even as I am looking through them I see that lots of people go with resonators or test pipes...The thing is, I don't know a whole lot about either, so if I could get some extra help, it would be appreciated.

      ... I'm pretty sure they all explain it...

      I mean what do you want? To get the cop's attention or not, to be able to converse within the car or not, to go deaf or not, to pass emissions or not, etc.

      You wanna play it safe, just get Techtonics

      TT 2.5 stainless w/ a cat and you're done... forever. The exhaust will outlast the car.

      Well emissions is VERY lenient here, i passed emissions without a cat on several occasions....but i dont want to be a cop magnet, just want to sound good! i want a nice low idle and a low to moderate sound. nothing obnoxious.

      I would also like to know if a test pipe is reasonable or not

      If you want to keep your low end torque stay 2.5".

      How much is that without the cat? I'll need a bung for a wideband too... Also, any vids of it? I was thinking of the MBSP that William runs, but those welds, clamps and Borla you got on there are really omnoms!

      I had the Bprla and cat, but you'd have to ask Dave for a price as most of my stuff kind of got rolled into one price with paint and some other parts. His buddy does all the welds and I must say I don't regret the money I spent. It's obviously not cheap like some of the bolt on stuff, but the extra money was well spent, plus it was hung really tight to the body so you won't see any of it (i know it kind of defeats the purpose of have such nice exhaust but I'll never worry about it.

      Doesn't he have a G60 not a VR guys?

      I've had a TT stainless system on my car since 1994. It still looks new. At the time, I was told that without the resonator, it would be very loud IN the car same noise outside. So, get the resonator. I don't know if they use the same grade SS now but the system I got has far exceeded my expectations.

      About a year after it was installed, the joint at the downpipe broke. I had one of their first systems so they still had a little to learn on these. I believe they use a better joint now but haven't looked in years.

      Also years ago, I knew a guy that went to the factory training on the Corrado. The car was very advanced for its time and VW provided some in depth training. One of the items was the role the cat played. Basically, the car is tuned to such a degree that removing the cat hurt more than it helped. I'm sure in the years since somebody has developed a tune that can get you more without a cat. I am buy no means a green, save the earth person. I did grow up in the 60's and 70's before cats. I distinctly remember eyes watering and chocking sitting in traffic. To this day, I can smell a car without a cat very clearly in traffic. The tail pipe on my Corrado is still shiny inside after some 40,000 miles on the TT system, no soot at all. In other words, the emissions work very well on these cars. Do whatever you want but all you are doing is making nasty exhaust with a test pipe.

      sounds like what you really need is a VR6 swap.

      ^I'm with Raven. Nothing better than a vr with a 3" system (not literally people) I was mostly just showing off my exhaust, I know this might not be the best option for every application but, LOOK AT THEM WELDS!!!

      haha if i had the money for that right now, i would. I LOVE this car to death, trying to make it sound decent, like i stated before, and I am trying to learn the ropes! Not only am I new to the VW scene, but to the corrado one as well.
      I mean, this may be a common post, but I really am looking for help.
      By help, I mean like the 5 W's of what I am doing.

      Right now I am looking at doing a test pipe because of the cat delete, since mine is hollowed...I am not sure if this is common, but it sounds bad. I dont have the money for a new cat, cuz i got school full time and work full time. No excuse though!

      That exhaust looked amazing up top, but like dogger said, isn't for the vr6? Even if it is, would it fit?
      Right now, I have a few tiny rust spots to eliminate, which i am learning how to do today, the next step is making everything FULLY functional. IE: motor/tranny mounts/thermostat gauge, and then onto getting all the pieces i need.

      I am just looking for which exhaust is gonna be the most respected as far as the car goes, I'm not looking to make it sound like a honda powered lawnmower.

      I stand by the tt ss 2.5" exhaust too. There's no reason to go up to 3" and loose your low end torque. I've beat up a lot of cats from speed bumps and the chip tune that keeps the motor a hair on the rich side.

      Every two years this car gets on a dyno for the CA emission check and the same spec's show up: super low emissions and instant pass for a smog check. The only time (for giggles and kicks) the car did not pass is when I allowed the motor to literally gut an aftermarket cat after contact with a speed bump. It was as good as a test pipe. It failed smog. Ironically, I've run a VR cat since then and it runs the same as the empty cat. The exhaust sounds better too.

      So far the best performance and reliability I've found is with a tt 2.5" with no center resonator and twin Borla mufflers. The VR cat is ceramic unlike the OE G60 cat. It's proven itself over time and should of been on the G60 to start. It loves to get cooked and flows phenomenally with the twin Borla set up. This set up is the deepest exhaust note I've been able to find.

      Off-Topic: For boost applications?

      Low end torque does sound nice, in the sense of a turbo setup since you lose a bit of the low end power with the lower compression but is 2.5" too restrictive when running in boost?

      You guys are starting to make me want to just go back to my original idea of catless 2.5 dual Borla TT setup instead of the MBPS 3", so stressful.

      P.S. Where's the video of that Straightline Autowerks exhaust?

      I still have no idea why people put test pipes on C's. The factory Corrado cat was proven to be very high flowing years ago so unless its melted or clogged thee is no reason IMO to get rid of it (maybe for sound and that's about it).

      OP if you cat is gutted and the case is in tact just leave it as it is (check the seals though) and put your $ elsewhere, you're gonna need it.

      Argument makes sense with those who are running legal setups I guess.

      However for those running illegal setups (Well I guess only in Cali is it really illegal to FI) might as well ditch the cat since we have to get illegal smog checks anyway... Right?

      2.5" should be fine if you run an open wastegate dump.

      The car isn't running right now, as I had some work done to the firewall, awic, and I have to extend the main harness a little further. Once I get the car back Sat, I will fire it up and let you guys hear it. I haven't even heard it yet either but the video on my build is with a full 3" exhaust too, it just wasn't pretty like the one Dave built me.

      Cali sux for car enthusiasts, except for the whole rust thing...

      If you have a big turbo setup I suppose its one less thing to go wrong in case you're way rich and cook the damn thing. I wonder how well cats and meth mix. < I smell lolcat pic coming on.

      yea 8v's sound like crap w/ super open exhausts. so I would definitely not go bigger than 2.5", and 2.25" is probably plenty. need at least 1 muffler and 1 resonator as well imo.

      hollow cat and test pipe are basically the same thing other than visual appearance, so no need to swap 1 for the other.

      another reason to keep a cat on a car (even if doing illegal smogs)? smell. My A4 exhaust smelled bad w/ a test pipe and o2 spacer, but didn't throw any codes or have any other symptoms at all. It worked 100% as it should, just smelled weird. I will definitely not be removing any more cats in my cars.

      Alright, so TT 2.5 exhaust for the G60 and dual borla exhaust then. Is what seems to be the most common setup. Any idea where i can pick up a g60 cat? or is it possible to UNhollow mine? I would imagine not, but its worth knowing.

      TT sells cats for G60's just get one from them if you want one.

      BTW what is a dual Borla? Dual outlet muffler??? Or do you mean dual resonator system with a Borla?

      Call them directly to make sure you get the best fit for your car there might be options that we didn't go over, and you're getting it from the horses mouth. They're great people over there.

      Pretty sure it's referring to no resonator, and 2 Borla Muffers, one midways and the other at the end. Setup I was thinking of getting.
