2.5"

[tag4car]

i just got my pair of flowmaster 40 deltaflows from partshopper, there is only one size listed, is 2 1/2" right?? it doesn't look directly like 2 1/2" on the stock underside, i'm going to weld it all myself (tig machine) and wanted to know if i needed to make any trips before i start..

all tips/info appreciated

:SNSign:

the stock piping is 2 1/4"

most(if not all??) aftermarket catbacks and midpipes are 2.5"

Yeah, that should work if your sure the flows are 2.5". There are a few people who do that.

well if I rember right the hanger are welded to the stock muffers and the stock pipe is 2.25. so a reducer of some king may make the job go faster.

so you will need to deal with those two issues. I would proably try to move the hangers to the pipe unless you bought the stainless flows. the facotry exhaust is stainless so it will outlive the flows if they are alumized. If you bough stainless you can put the hangers either place.

i got them in stainless, i'm going to take it to a shop in the am, the guy there will install them both for like $60, i've got all the tools to cut weld and shape, i just don't have a lift at my side to help me...
