Hey everyone. I need to fix my exhaust and am looking for the simple and cheap way. One day I will pull motor and do the bucket list with proper down pipe. I currently have a straight pipe with muffler and broken welds in places, honestly just a terrible hack job of an exhaust and is why I'm not going to use a muffler shop or whatever.
Has anyone had experience tying a 4" diamond eye cat back with muffler delete (some straight pipes to 45-90-45 bends I suppose) into another pipe section to a 4"-3" reducer from the 3" dp collector that I hack off after the connected 2- bolt flange? The picture is there parts I'm looking to add to the front of a diamond eye or whatever is cheapest 4" over axle pipes.
Here is where I would cut behind the dp flange.
Cut just before the shoulder
Oh, and of course feel free to reply with a link to a thread. I searched for 2 hours before posting but maybe it was one of the other hundreds titled "my [blank] build" I didn't read through entirely.
Thanks

Reason: cut
What I think is strange it's the cat back 4" kits from mbrp or others look like they reduce down to 3" at the front. So would I have to saw that off before the reduction and flare it (with expander) to set over the 4" pipe I'm buying from summit, and if so why waste money on "mbrp" pipe all from the same metal... aluminized steel one can find anywhere.. is it as easy as buying a 45, 90, and 45 to build the over axle hump, cutting to size to get proper angle? This would be first time I've built over axle, I have built pre axle dump exhaust on gassers quite a bit, that also don't see the high heat a PSD does.
I have 3in for first foot or so of pipe off turbo and rest is 4 in
you can use 45and 90 to get your bends and use HD clamps so it wont come apart
it can be fun to match it all up
price it out too, the clamps, 90, 45, hangers and adapters add up fast and once you are up to half the cost, the pre bent kits are less hassle to install

Oh you are right, it's literally same price but the kit comes with hangars pre welded in correct place? If so that's a no brainer. I've only bought a kit once over 10 years ago and the whole box went in the bed of the truck to the shop my friend worked at and installed. I don't know if they come with hangars already?
