downpipe vs catback size
If i have a 2.5" catback would it make sense to get a 2.5" downpipe with high flow cat, or is there a benefit to getting a larger downpipe? (Will it bottleneck at the 2.5" exhuast anyways? etc...)
And I already searched, nothing specific came up. Thanks in advance

your exhaust is only as big as the smallest point in the exhaust system. i do not see a 3'' dp going to a 2.5'' cat back being helpful. I could see it creating flow problems. talk about air turbulence. you best bet would be to get a 2.5'' dp with a high flow cat, or catles
