Beautiful Product
Great product quality at a reasonable price and was shipped quickly after ordering. I was anxious to get it on my car but found that the side exits wanted to occupy the same space as the welded in frame connectors. I was bummed! It would be good to write that up in the product description to be aware of this interference. Four stars only because I really don't know what they would have sounded like.

Beautiful exhaust kit in every way!
Beautiful exhaust kit in every way! Sound coming out those (Borla) mufflers is smooth and intoxicating. Especially right outside your window! Sounds like a crazy race car on my termi swapped GT. Talk about catches attention! Only down sides are ground clearance and the fact that the rocks flying off my front tires has really peppered up the tips and I have only put about 3000 miles on them. Still extremely satisfied as I am willing to put up with being extra careful over uneven surfaces. After all I am driving a lowered Mustang so I am used to this anyway. Chose this kit to go with my future plan of installing a Steeda 5 link setup with a Roush body kit. Certainly glad I did! Thanks Steeda for making some of my most favorite upgrades!
