Exhaust leak! But where??
If anyone can help me out i would really appreciate it! Recently got my car tuned and got the “ flame map” along with it. I knew I had a small exhaust leak on the flex pipes on Y pipe because my car being so low it hits on my drive way gate rails. Well anyways, I was having fun being dumb and ripping the flame map the next day after getting tuned (Saturday) now on Sunday I went start the car and the cold start was idling under 1k rpms. Thought it had something to do with the tune but my tuner said it has nothing to do with cold start. So my thought was that the “flame map” finished off the flex pipes and I had a huge leak now because my cold start was under 1k rpm, and when I would accelerate from a stop it would sound like air fluttering. A week later I get flex pipes cut off and welded a pipe for now till new Y pipe gets here. But I still here fluttering and cold start idle is still under 1k rpm. What could it be? I’ve legit looked at the whole exhaust and have no leaks anywhere else. Maybe exhaust manifold? Please help! Thanks!
P.S. sorry it was long af.

it does sound like an exhaust leak to me any anyways...check your gaskets at both ends of the Y pipe and replace them when you get your new y pipe... or hook a shop vac up to the tail pipes in reverse and start spraying along the length of the exhaust with soapy water and look for bubbles...I have heard of people running seafoam and checking for leaks from the smoke too that might be easier...GL

Pull vacuum line coming off master cylinder. Shove the hose half way down the can of seafoam. Start car rev to 3k rpm and hold until you see white smoke then turn off car. Plug hose back into master cylinder wait 30 mins then drive the car like you stole it bc it will leave a plume of smoke like your car is on fire it goes away after a min or 2
