Exhaust H Pipe

Exhaust H Pipe
Anyone know a good source to purchase a H pipe for the exhaust? I want to replace the centre muffler and prefer to not have a local muffler shop make one from scratch. Milltek, and other suppliers, will not part with the H pipe alone unless the entire exhaust system is purchased. Can't blame them as they put alot of R & D into their products.

For what it's worth, after pricing out what's available on the net, I fishmouthed a piece of exhaust tubing and had it welded in between the two straight pipes. Works very well to balance the system. Very little cost. I think it was magnaflow amongst others that makes them. Google. Good luck.

I'm curious why you don't want the muffler shop to make one from scratch. There isn't a whole lot to an H-pipe (compared to say a X-pipe or ProChamber) and a custom job is probably cheaper and easier for a shop to do. Here is what I did (although I did the entire system, you could just do the H): https://www.jaguarforums.com/forum/s...ad.php?t=37811

I agree 100%.They can build you any type of system that you want.Any size piping.Bring in your own Stainless steel pipe if you have some?Bring in your own special mufflers if you have such.But I would go with them.They will build it to fit the car.A lot of time you can buy a H pipe system and have to go in to them to have it altered to clear linkage or?

I have done a lot of exhaust R&D on the XK and I can tell you a H pipe will sound better but an X pipe will give you more power, we are not talking about alot here just a few BHP, I always prefered the balance pipe (H) idea over the X but dyno's have prooved otherwise. Either is very easy to make, I would even go as far to say if you have a MIG welder you could do it yourself with just some pipe, making it all up in situ going with the H idea would be childs play!
And I agree with Brutal the OE system is all stainless but the tubing is poor quality and will still rust!

its just depends on the amount of ferrous metalor grade, a magnet sticks to it so its got some iron but compared to a true steel, its great and rust prevention. We can always spot nothern market or beach car depending on how much rust the exhaust has. otherwise we dont see any here in Houston

Does the existing centre muffler act like a H pipe but with a lower noise? If it balances the exhaust pulses between the two banks and scavenges the exhaust more efficiently I may look at just going with straight through pipes after the centre muffler. By getting rid of the four rear mufflers how noisy can the exhaust be?

Sounded pretty good you do get a slight amount of resonation around 1500 rpm but nothing to write home about,

Rev, as an engineer you should know that there are different grades of stainless steel,and some will have different corrosion levels.Remember the reasons for specing 316 over 304 SS enclosures? Attached is some fun reading.

We didn't really cover metallurgy in electrical engineering school. However, I was under the car again today and I noticed that the rust was just little specs scattered all over the exhaust. I guess if it wasn't stainless it would be completely covered with rust. I was kinda expecting stainless steel to be all silvery and shiny. Shows you what I know...

I like the balance and sound from the x pipe,you can get a nice one from Magnaflo for less than $75.I had my local shop cut out the center muffler and weld in the x pipe,I also had them remove the rear mufflers but keep the ones that are in the back side. The sound of the new system is awesome!

I'm trying to find a good solution without springing for the whole MacLeod deal. I'd like it to sound more civilized than my solid-lifter Corvette LT-1 (which my wife doesn't even like to ride in) but I don't want it to be too wimpy. The Mina system is probably good, but I just don't like the looks of their tips. I really prefer having an oval with a rolled edge. It looks like Mina's tips are welded on and close to the mufflers so it would be a hassle to change them. Sigh - someday I'll find the right setup.
