ok... i just bought a 2003 WRX... and now im broke.. haha... and my friends for a good while had this Team No-Exhaust joke going on... they basically just took off there mufflers... i was wondering if this could be a cheap way to get that beautiful boxer sound out of the car.. i know it didnt hurt thier cars.. but im new to turbo.. i just figured its passed all the sensors so it wont cause a problem... anyways.. let me know what you think...
Let me just tell you from experience it's rediculous. On my 03 when I was installing my exhaust and all I took it out with no catback on, was cool for the first 15 minutes when everybody and their mother was looking at me while I was reving the hell out of it at stop signs, lights, and other cars. The best way I could describe the sound is if you have ever heard a car with a cutout but louder that was like the difference between it with a catback and no catback. I also had the hks hi power so I like to make some noise but no catback is just too much noise.
I had to run out and get hardware when I installed my TBE, so I ran into town w/o the cat-back on and it was slow as hell, no torque at all and was popping like you wouldn't believe on decelleration. Overall thats a bad idea, save up and do it right. Like 9d2TSi said "this isn't some P.O.S."
I had my cat back off for a short trip down a few streets. It lost all power and got kinda choppy under 3k. Up top it felt a little more powerful, but when you slow down it cackles and when you stop you get a little overwhelmed with exhaust fumes. The sound did put a smile on my face even though it was seriously abnoxious. Gotta love the boxer engine!
