I gave $83 dollars + shipping for them.
No emissions (not tested here).

What do you think of them?

I'm not gonna do much more for this LG4, mainly want a better sound and better performance/gas milage will be a plus.

I have Flowtechs, I think they're outstanding. Don't forget, you'll need a y pipe too though.

 

All I can say is no. I used to be a Mustang guy and had some FLowtech stuff. I took it off once, and it never resealed. They were ruined after only 1 year. Flowtech products are junk. If you care about quality, I would go with Edelbrock or SLP.
