New Problem!! =/

Well it isnt really new but everytime i start my car it sounds like a damn muscle car!! I just replaced my downpipe so i know it isnt that. Has anyone had this problem with their SL sounding like a old muscle car?

my car is a vr4 but do u park your car outside in the cold ? because when i put my car out side in the cold and turn it the next day some weird noieses come out of my car to but it goes away as soon as the engine gets warm.

You might have an exhaust leak...you mentioned the new downpipe...usually when you replace the downpipe you want to use new gaskets and also retighten the bolts after 50 miles to prevent exhaust leaks.
When I put on my header on my Accord, about 100 miles down the road, I got 2 exhaust leaks. Both ends started leaking because I didn't retighten the bolts, and because the gaskets sucked. (use copper, they are the best and only like $8).

Also, when you replace the weakest part of the exhaust with a new piece, that is suddenly the strongest part, and some other part becomes the weakest. And the pressure will break through the next weakest point...so if there's another part of the exhaust that is bad then it's next in line to break open. Which, if you're car is still loud, probably happened.

i dont understand what your saying, and i didnt replace my gaskets... so maybe why that sounds so dam loud?

If you put a new downpipe on, and you reused the same stock gaskets from the old downpipe, you probably have exhaust leaks...

Yeah you definitely need to use new gaskets with new exhaust parts...get under there and see where the noise is coming from! If there's no leaks anywhere then your new downpipe is larger or has thinner walls than your original and is loud.

i don't understand what's wrong with your car sounding like a muscle car? enjoy this hiccup!

my car sounds exactly like the pontiac GTO in the commercial when it is just sitting at a green light. thats idling tho..
