Need Advice On Performance Muffler
Hello Everyone!
I am new to LSI Tech, this is my first post and I am looking for some advice. I have an 03 Yukon Denali 6.0 with 3" factory exhaust w/dual in dual out factory muffler. I purchased a 2.25" dual in dual out Thrush Welded muffler. When I took the Thrush to the shop for install the mechanic told me that going from 3" to 2.25" would restrict the air flow and ultimately cause damage to my motor. Is this true?
I have been looking for 3" dual in dual out mufflers and am only able to find 3" single in with 2.5" dual out. Can I go to a 3" single in? I am at a loss as to what my options are. Any advice is greatly appreciated!
