What kinda of Integra?

Hi,

Tonight me and my friend were on the interstate in his 99' Sunfire GT with a few mods like Intake and dual exhaust.
We are cruising on da interstate coming back from Tampa heading north and this integra get right up on our ass with his brights?
Either he had his brights on or they were just really bright bulbs.
ANyways, he gets next to us and takes off and all I see is the rear end of his car pull like crazy past us. By the time my friend took off they were already 4 or 5 car lengths ahead.
But the funny thing was his muffler was scraping the bottom of the road everytime he hit a dip in the road.
my question is, do you know what kinda integra this coulda been?
Im not sure but I may have heard a turbo but our windows were rolled up.
You think it coulda been a GSR turbo? It definetly wasnt slow.
Thanks

Sunfire GTs arent that fast. Theyre slower than almost any sport compact. It couldve been a GSR with a few mods. Maybe a type R, but any integra GSR or ITR can pull pretty quickly from a roll against a sunfire.

could be an LS turbo ITR or GSR pretty much anything will take one from a roll even the GTs aren't the quick.

it could have been a lot of things, from that description that you gave, its hard to say what it was, someone needs to learn some english before asking questions "what kinda of integra?" or what kind of integra, or even what kinda integra, but that still doesnt make much sense, you need to explain things better if you expect us to answer
