EPnick22 Posted January 1, 2014 Posted January 1, 2014 someone I know is just running a decat with no exhaust on his car, internal wastegate.....to be fair it sounds pretty savage is this bad at all? Opinions Quote
Amjad Posted January 1, 2014 Posted January 1, 2014 Lol if that's the case it should sound like a tractor. Started up my GT like that and it was horrid, on boost was savage though lol Quote
EPnick22 Posted January 1, 2014 Author Posted January 1, 2014 yeah on boost it sounded good, thats what i meant, when idling it sounded a bit unhealthy lol surely there would be no back pressure? Quote
TurboTobz Posted January 1, 2014 Posted January 1, 2014 yeah on boost it sounded good, thats what i meant, when idling it sounded a bit unhealthy lol surely there would be no back pressure?after the turbo th3 gasses are useless no backpressure required for forced induction shouldnt sound much different to a front exit reallyAlthough the sounds like tractors anyway lol Quote
daniel_g Posted January 1, 2014 Posted January 1, 2014 My 85 has no exhaust atm, its not on the road yet so its all good, theres a vid in my thread thing of it running and it sounds like a JCB haha. Also when it was still N/a i drove it up the street with no manifold or fuck all haha, loudest thing ever lol. Quote

daniel_g Posted January 1, 2014 Posted January 1, 2014 no manifold?! you mad bro?! hahaYes mate lol, i took it all off when i was stripping the car down and thought it would be rude not to start it up haha. And before i knew it i was driving up the street in basically a spitfire haha. Quote
mikey4410 Posted January 1, 2014 Posted January 1, 2014 Turbos require least possible back pressure so ideally nick its ideal mate.but way to loud.ran my first starlet this way when I sold the hks full system to pay towards forged build. Quote
EPnick22 Posted January 1, 2014 Author Posted January 1, 2014 its alright I enjoy tractors ;) haha think I prefer the sound of my exhaust. probably going external soon, going to put my welder to use Quote
jellybaby Posted January 2, 2014 Posted January 2, 2014 It shouldn't do harm how ever depends on what ya traffic police are like they have u over a barrel with noise pollution also they might and say might dig around and check ya car is correctly insured ie mods declared. For track yes run with out one if less then the noise allowance. For road I wouldn't run the risk of getting pulled over and ending up with a twat of a police officer Quote
Jamie5414 Posted January 2, 2014 Posted January 2, 2014 no exhaust going down street, blip throttle sounds like backfire when going over speed bumps epic Quote
