Loud, Sound great, Fit great
Neal J. on
I installed these on my convertible with the stock manifolds and stock cats. The sounds is deep, and aggressive. The fitment is perfect and the tips look great. These are probably one of the loudest mufflers or lack of mufflers that you can buy.
** When installing single 76mm turbo with not catalytic converter, I went back to stock axle back. They are extremely loud when removing the catalytic converters. Loud is for some people but being a daily driver made me take them off.

Had a problem with an order/quality issue. I put up a review stating so, and was contacted by Mike Linley, who was soooo nice and sooo professional, I almost felt bad about my review !! I felt the review was necessary because of bad welds/paint. Mike explained that they had a particular issue with that supplier and they had changed suppliers because of it. I must have mistakenly got an old set. (upper/lower Control arms-Foxbody). Mike asked a few questions, and was Sending me an updated replacement set while we were on the phone.!!! This is what I wish all Vendors would do; no arguments, no blame, no B.S. !! This is why LateModel stands out as an upstanding company, and backs up their products with AWESOME Customer service. Very rare in this day and age, and because of this I will be a customer for life, and will spread the good word ! Great to know some honest and Classy companies still operate in the good ol' USA. Thanks LateModel, and Thanks Mike !!! I look forward to seeing the New LCA'S and will review them too...You guys did the right thing and should and I'm overly impressed!
"Just a 2 valve" is what I hear consistently. Up until it comes time to actually put up or shut up. This car isn't the typical drag mustang. Its built for the road coarse. Makes a whole whopping 300rw...
