One of my co-workers' some how obtained a pair of Megan Racing downpipes or cat-delete pipes, and has no use for them since he doesnt have a G or Z, so he just let me have em. I have an 04 5AT coupe (stock) and was wondering if I should sell them or just put them on. I really don't want my car to sound like garbage, and I'm trying to keep it stock really... But it's free, so should I, or should I not?

 

They're called test pipes. They are not street legal. There are some threads about them. Makes your stock exhaust a little louder, may add some rasp.

 

Hmmm... I'll get rid of em. no use to me then. Thanks
