Exhaust Cross Pipe for use with Record Monza

We are making up some new cross pipes. I love my Record Monza exhaust, and I'm not willing to replace it. Furthermore, the mid pipe that it connects too, isn't bad, in fact it's actually superior to many aftermarket parts in some conditions (power, rpm range etc.), but the cross over pipe is a bit too restrictive for my current project. As far as I can tell, there are no cross pipes on the market that will connect my stock cat (which I'm also keeping) to the stock mid pipe, which I have to keep in order to keep my Record Monza. I'm sure you can see where I am going with this.

So, to solve this problem, I have made up a free flowing cross pipe. It's 2.25", stainless, and has enough clearance for some extra insulation since I don't want it heating up the oil pan, clutch, or slave cylinder. There is a good reason the factory put that heat shield on the factory part. My prototype isn't exactly pretty, (I'm a mediocre welder at best) but I'm very happy with the result. At the moment I have it at my machinist's shop. He is making up four of them, which will look nice, he is quite skilled. No pricing yet, no dates, obviously limited availability. Since not too many people have the Record Monza we are not going to make 100 of these things, but I thought I would give you guys a heads up on this.

@Greg - where do I sign up? Definitely interested. Been looking for something like this for a while. I want the crosspipe to free up flow a bit, but otherwise I'd like to stay stock or add the RM.

@Greg
Since the Record Monza is just an axle back exhaust this will benefit those with the Auto-Ricambi and AFE axle backs as well because they all utilize the stock mid pipe.

I'll worry about a sign up sheet once I have pricing and a picture of the finished product. I really don't think demand will be high, so this shouldn't be an issue, there just are not that many Record Monza cars out there. I have never seen another one in real life, and very few on the forum.

Hmm, good point, I hadn't considered that. I suppose I am thinking in terms of Record Monza since that's what I have, but yes it would clearly work with anything using the stock cat and mid pipe.

Yeah - I think demand may be a bit higher than you expect. The crosspipe is generally considered the big bottleneck in the system and I think a lot of people with otherwise stock or axle back updates will be interested.

Agree. I'm not entirely happy with the two piece mid-pipe but I do like the overall sound of my car. I don't plan on changing anything at this point. I think I would have been very happy with just a better flowing cross pipe and the RM setup. @Greg, you might be surprised by demand.

be surprised sign me up!

I'm all stock except for the AR axle back. I like the fact it will be plug and play.

I'd if anyone else said it...SHOTGUN!!!!

Greg's direction would have been my preference all along. I can't spend more money on exhaust, though.

This isn't a product I have particularly high hopes for in terms of sales, but it's one of several new things I needed anyway for my build. It's just one of the six new products I needed for this project. I already mentioned the pistons, and the others will be unveiled as the project progresses.

I would much rather have a Record Monza with a high flow crosspipe and a midpipe without resonator. What will be the INLET diamter of your crosspipe? Will your crosspipe fit an automatic?

Don't go there. You know you need custom wheels and coilovers next. ?

LOL :LOL:
I am going with 2.25" because that's what's needed to connect the stock downpipe to the mid pipe. It's hard to say if it will fit the automatic or not because I haven't tried it. As soon as I can, I'll find out.

Greg, on the cat side, will the hole in the flange be 2.25”, or will it be smaller to match the OEM cat outlet?

Shark, It's 2.25, which actually is the largest diameter of the cat's outlet,and the mid pipe's inlet. I say "largest diameter" because a lot here depends on where you measure it, but the way it looks to me, a 2.25" cross pipe is the perfect size to connect these two things, and it's plenty of diameter for these cars.

I would like one... I have the factory Abarth setup back to the axle, then the Top Speed axle-back. The cross pipe is the one other thing I would change.
I would love an option for a better flowing cross pipe without having to replace the rest of the exhaust. I already splurged last year on a muffler delete from AR, and the only option I see now for a crosspipe is the Goodwin system that would set me back another 1400....and possibly be way too raspy from the increased midpipe diameter.

The GWR RoadsterSport System isn’t raspy at all with the resonator.
