gains from Mac mid length I need some feedback on this mod.If i was to put Mac mid length headers with cats and a Y pipe on my convertible what would my gains be in the way of HP.I've been told i may gain 5 HP,that would be a joke for the $1000.00 investment.
What do you think.If i could pick up 15 ponies i would do it.

You can pick up Macs with an ORP for $499 last time I checked.
You can expect a solid 20rwhp after macs with a tune. (Hell, you can lose 5hp after a header install if your a/f is thrown way off!)
However, I would have gone with Hooker LTs if they were available when I installed my Macs since the price is similiar.

You will pick up roughly similar top-end gains as with longtubes.
Longtubes would have more mid and low end power, and slightly more top end.
I'm happy with my Macs, I made 410rwhp/415rwtq N/A through them with 3" CarSound cats.

Hey bro,
In my opinion, I would stay away from MACs. I only say this because I helped install a set and I thought that they were a PITA to install! Not only that, I'm sure that within a matter of time you'll probably want to swap them out with long tubes. I would just get the long tubes for around the same price.
Good luck modding...

I picked up mine for 260 and I thought they were super easy to install (both from the top). I am make decent power with them. I got them cuase they work, they were cheap, and easy to install.

You can get uncoated Pacesetter LT's for 279 at Texas-Speed. But thats not what you were asking. I have heard gains are very similar until you start modding big. What are your plans for the car? That's the biggest question I think. Don't do something you would regret later on down the road....

Longtubes hang low on lowered cars.I have to be carefull going over speed bumps now,entering driveways can be a bitch too with another person in the car.
The mid lengths look like they would tuck up in there nicely.It's a tough issue,i want to make the right decision.
Now I'm not sure what I'm going to do.I am getting headers one way or the other.
Like i said,if I could pick up 15 HP with little Macs and a tune I will do it.From what you guys are telling me I very well could get the 15 HP I'm looking for.
It would be cool if somebody dynoed their LS1 after a little Mac intall.
Every little bit helps,I noticed a difference when I swapped out the SLP lid with the TSP lid,it wasn't a big difference,but I felt the slight change,

I dynoed 293 hp and Tq with a lid and muffler. After installing my small T1 cam and Macs it made 374 hp 372 Tq. This was without an LS6 intake or ported TB.
I also had a buddy who used to have a Procharger on his T/A. He had MAc's headers and Y with Corsa catback and put down 548. I don't think they are much of a restiction and I think they make decent power down low. I just couldn't pass mine up for the deal I got them for with the Y pipe.

I gained 21rwhp and 14 trq on a stock internal motor. When I dynoed it was over 100F.
