I am getting a set of dutras that come with a set of 1 7/8" head pipes, I just had my single exhaust done as a 2.25" flange to tip, should I run the 1 7/8 to 2" to 2.25"? Or is there enough room in the engine bay to route another 2.25" pipe? On a budget, but I don't want to hack up my newish exhaust if I can spend a little more and get better flow. Also doing a super six upgrade with a Holley 2300.

Thanks,
Seth

2" headpipes might be optimal, but 1-7/8" headpipes should be plenty adequate, used with a Y-collector conjoining them to a single 2¼" pipe to join up with the rest of your exhausting exist system.

Ok, thank you Dan, helpful as always!

Just got off the phone with my exhaust shop, I'm going to leave the Y that is on the head pipes already and I'm going to take it into them and pay $3 to expand the 2" collector to 2.25", it was either that or 60 to get a new one fabbed up.

Should be fine.

Seth, I don't recall mentioning that there was a Y pipe on them, I apologize if I said that there was. I've been running them as true duals for quite awhile now with those lakeside pipes.

I did have a Y-pipe at one time, but it was crappy, and I wanted more snarly noise from my car.

Just thought you should know that before stamping plans into concrete. See you later today!

I remembered you having one in your videos, but its alright, I'll just grab one, I know where a couple are, I'll have to see the head pipes first, I may just fab one, I have all the tools to do it myself, I'm just not a great welder. You have manual steering though, don't you? That may throw another wrench in plans, I have power steering.

Those are old videos now.. glad someone watches them occasionally...

Nope, my car has power steering... and a manual... it clears both of those, even with the small engine compartment... you should be fine.

My suggestion would be to make a new front pipe. It works, but it needs work, and it would look tons better if you replaced it. You should be able to use it as a pattern at the very least.
