Claire I. ★★★★★

Installed the flange and extension pipe kit on my truck and saved a ton of cutting and welding time. The metallic cat body feels solid and the 400 cell flow is noticeable at higher RPMs.

Chloe ★★★★★

Bolted on my 400 cell cat with the included flange extension and saved an afternoon of cutting and welding. The metallic substrate seems solid and the stainless flanges lined up perfectly with my existing pipes.

Ella ★★★★★

Welded this up on a Saturday and it fit the factory hangers without any cutting or tweaking. The 400 cell metallic core flows way better than the stock unit and the note at idle is noticeably deeper. Having the flanges and extension pipe in the box saved me a second trip to the parts store.
