Stock exhaust size?

[87gtconvt]

I should probably know this, but what size flowmasters will fit on my car? I took off my mufflers and the pipes off after the H pipe and it's a little too loud for jesus-city wheaton IL. I'm thinkin 2-chamber with some side exhaust should do the trick. Thanks

2.5 will do just fine you wont need any bigger.

If your just looking to throw some mufflers on a stock system, you want 2 1/4"
